hmm, ok. anyone here using that falkor mirrored ambi? Trying to decide what set to dump my bucks into, because I only want to do this once. Really want to drum up a BUNCH of responses full of reviews. All that 'good, bad and ugly' type of stuff. Please, pull no punches. I like how the matrix seems pretty sturdy. Decent looking and I like the tension detente. Rainier ultra match 308 currently rings $550 from their webpage. Seems about in line with all the rest, really. They claim it is extremely parallel. Mega had my interest to begin with. I may just opt for one of their monolithic types.. *shrug* What is a standard price for a blemished matrix set?

Matrix and Mega seem to have the most consistent reviews. What about the raniers ultra match? No one seems to be on board for the falkor. Is this because falkor is out there on the fringe of the billet receivers? Seems like Mega is the number one pick. I did look at their megalithic upper, it is nice. Was originally what I was planning to use. Those matrix do look decent. Also, I agree - forward assist is pretty much unneeded. Just one of those things. Keep the receiver inputs coming! Thank you everyone.

Why on Mega? I heard they are very tight fitting. Which, I suppose is a good thing. Any other reason? Also, what is that weird set screw they advertise as being a selling point. About tolerance between the upper and lower. What set are you currently using?

So, the falkor would be good to go? Proper and quality measurements, no issues with fitting? No known issues to be made aware of? I know it looks a bit.. ugly, but I almost like it. In a strange way. Plus, the mirrored ambidextrous controls seems nice. What is the word about their bolt carrier group, vs the rubber city and JP high pressure offerings?

I have been looking around some. Seen mega, rainier, a few others. which set do you all like? How are those falkor defense receiver sets? That one looks good to me. Which ones to avoid? I took to thinking about what someone said in my novice thread about using a different receiver set. Saw another person mention falkor. Looked into that one. I like it more than some of the others. All inputs and experiences would be great. Thank you. Oh, I want to avoid poorly cut lowers. Out of location buffer detente bores, bad consistency and alignments. Prefer more tight fitting upper/lower mating. Intending to stick with matching sets.

I was made aware of criterion 308 hybrid contour barrels. Looked into them. I like the 18" rifle length gas 1:10 twist m118 chamber stainless nitrided barrel. Where do I get it? Their webpage says CBI distributor. I click that and it takes me to an email application page. Who is a direct vendor/dealer that could order this barrel? Seems like a better route to go(cheap) vs a more custom made barrel. Nitriding seems to have reasonable review for most parts. Been evaluating a build, if anyone noticed by my novice thread. Thank you all for helping so much already. A great community here. Newb

Hmm, sounding more and more like heavy buffer with non-adjusting gas block. Use the PRS thick recoil pad on MOE rifle stock and quit my sniveling then. Less 'adjusting' parts may be better for my desired goals. Plus, will help even out the weight distribution on this rifle build. An adjustable would be nice, but for the same price a heavy buffer can be had. Thinking it will allow a more broad range of rounds to function.. Anyone ever having issues with that Syrac adjustable gas block 'recoiling' out of adjustment; A bunch of rattle and recoil making it click to a different setting? I am guessing that unless someone runs at the ragged edge of gas, just one click more/less may not be that noticed. *shrug* It would seem redundant to go heavy buffer and adjusting block unless I just hated money and had to have no doubt the softest feel possible. Funny, how perspective changes with a deeper evaluation huh...

Yes, I meant to turn the adjusting screw. What do you mean by moving the block in relation to barrel for gas signature adjustments? I am a bit confused. The position of the block in relation to the barrel can also affect things? This would make sense, with how much the ports are in line with each other.. I was also considering what you mention about a more broad range setting. If I am doing that, may as well go non-adjustable and run that heavy buffer by slash right? Please, more information on adjusting gas signature! Thank you so much!!

I heard it had something to do with originally the 45acp was slotted for using small primers. However, the m1911 was so loose and out of spec that issues arose that firing pins were not properly located in the breech face. This brought along the 'repair' to use large primers. Small primers actually support higher pressures, if that is a real concern with those low and slow rounds. I have only had federal and blazer brass come with the small primers. I only notice when going to prime them. Ugh! *junk brass can* Still the best darn pistol cartridge around.

survivalshop - the gas blocks operate in similar function if I understand. Simply, the syrac uses a detente that prevents rotation where as the inhouse model is used with a loctite. Am I missing something here? I was probably going to opt for building it myself. Pick up the parts as funds allow. Save a few bucks in the process while retaining their 'rifle' for what ends I have behind that. Seems I am a bit confused. Both of those blocks place obstructions in to the gas port. I was under the impression two very similar loads (one hunting, one for plinking) with a bit of compromise in 'recoil' I would be able to utilize both after the block was set. More insight and input would be very appreciated! Fletch - RCA shows their forward assist 308 bcg ringing in at 19.9 ounces. I would guess that both JP and RCA are almost toe for toe in the heavyweight full mass class.

Thank you all again! Anyone know the weight of the JP low mass and full mass bolt carrier groups for comparison? Glad to hear the input, Fletch. Any reputable barrel+extension should properly headspace with the RCA then, most likely.. Sounding like I am going to start working on a plan. Coming out with: ----------------- 5R Liberty barrel by Satern. 18" 1-10 twist rifle gas system. is a medium/heavy contour with fluting beneath handguard. Possibly referred to as special purpose rifle contour? It showed a 'thick' medium contour beneath the handguard with i believe five flutes. RCA BCG - Looks pretty decent. Thank you for pointing this one out. Local builder's receiver+float tube set and in-house gasblock. CMC two stage trigger. feels like 3.5-4# *shrug* unsure on weight. Surefire ProComp brake. TacOps charge handle Mech Armor flip up sights. Seekins K20 foregrip. A tricked out Rhodesian Sling from Andy's Leather. They are top quality, if you shoot like a scout. ------------ Going to be playing with H4895 powder and 168/175 sierra match kings while climbing ladders to dial in a blistering velocity that prints consistently. Want to say thank you to everyone so far! This is a great community. Unfortunately, I am not made of money and this is all my footwork before delving into a custom build. Local builder has a surplus of primary components (barrels included) so, I am hoping to have this thing going this fall or next summer. Saving up for the spring national pistol bays in Mesa AZ for 2017. If any of you are around that area when Rio Salado Shooter's Club hosts.. be there! That staff is amazing and puts on one heck of a show. Need to go visit my powder supplier and pick up a load large enough that rises FBI interest too. =O God bless Bush Jr. and his ability to remove our privacy. If anyone has some insight, recommendations or tips from experience - please inform me! Thank you all so very much, The Newb

interesting to know, fletch. Thank you for helping cement some thoughts. That 5.5oz buffer in your carbine is about on par with the 5.4oz rifle buffer, so.. Do you really feel that the JP would be a better pick over the rubber city? I am almost inclined to think that JP comes with a premium cost. Materials seem the same. However, with their JP premium comes a bit of that well paid research department as well.. However, for $200 in difference.. These rifles can add up pretty quick in cost. How did that RCA bolt headspace? The QPQ finish wearing decently? Anything else you can tell me?

Thank you for the inputs! I was thinking the same thing about rifle stock. I only like the A2 buttpiece because I need a swivel on the bottom, not one of those new aged fangled up "QD CUPS" on the side for some slicked out nylon sling. I am well aware the MOE buttpiece has a decently replacable rubber pad and some blind holes in the 6 o'clock position for rails. Unsure if I could put a sling mount in there with little to no issue. anyone have experience there? I am thinking that my build preference is shifting somewhat. Maybe that rubber city bolt carrier group for $300, a standard buffer/spring combo and just spin the gas block a bunch to be hardly gassing at all. Probably going to stick with that 18" barrel though. Was looking at the mech armor defense tacops charge handle and battle sights. a bit cheaper than other routes, plus seems to have good reviews. I do not mind the HK style front sight either. I agree - irons are pretty handy and hard to beat. The ONLY reason I ask about the standard style sling orientation is because I am slotted to use the Rhodesian Sling. I like being able to draw up for shots at range. Plus, that sling weighs a small truck tonnage of difference when compared to a bipod. Not to mention - doubles for when I am tired of holding this blaster...

sharp shooting! You mean the set screw with the detente? I looked at syrac's webpage. midway says discontinued. hmm.. Why is the general thought I will want to change my float tube? I handled a fully assembled rifle with the exact tube just last week - felt fine. a few BCM keymod rubber inserts are easily fitted, if any issues arise. I am just confused here. Please enlighten me =D!! It may possibly be barrel harmonics or just a generally 'wrong' amount of charge weight/type for your rifle, with the 168's being better. sometimes, it is hard to tell as rifles get picky. How far are you capable of hitting with that rifle? Know what your muzzle velocities are looking like with federal gold match? What are the reviews on those rubber city bolt carrier groups? Their high pressure 308 bolt carrier seems a bit cheaper than the JP similar offering. Although, I am unsure why it is fluted.. *shrug* maybe that with an adjusted gas system will do the trick for powder puff recoil. AHAH! It seems to me, you are using the M4 buffer tube extension. Does that mean you are using the 5.5 or 6.5oz buffer? @ survival shop Them are some slick rifles as well. You do not see any need for the heavy buffer either? Well, alright. I am just trying to get something that works. I always liked those round tubes you show on the 18" rifle. They capable of any attachments, or is that just one of them fancy low weight ringer-dingers? So, in a go to grab it and run rifle - the sixteen inch barrel is your pick huh? Any reason why? I keep seeing all of these spacers to use carbine buffers and springs in a rifle length extension tube - why? Someone educate me. Also, are there any of those high density tungsten powder filled 308 buffers? I was under the impression that the rifle length extension tube and rifle buffer/spring combination would 'smooth out' must recoil impulses, in comparison to the carbine lengths. such as, if both tubes were used with identical weight buffers, the carbine length buffer/tube would still 'kick' more. MORE HELP PLEASE!! by the truck load..

I am likely to never change handguards though. The keymod seems to be easily adaptable for most things, be it directly keymod or a 1913 rail attachment. I also value the input. Was thinking the 18" would be the best compromise. 16" providing issues with reaching out. The 18" should retain enough velocity to make a 600m shot reasonable. Yea, I have been told the 16" will do that. The guys had a 18" Liberty barreled (broached Satern barrel) keymod railed rifle on their wall for display. As stated previously, weighed in between 9.2 and 9.3 pounds. scale kept changing. This was minus magazine and sighting means. The handguard will also support the MOE attachments where the slots are. *shrug* Also, I was not intending to ever sell either. Simply.. the group is expanding, I know most of their sponsored shooters as well. Interest was expressed in my concept of a build. They are asking $2000 for the complete rifle in my color of choice equipped with the a2 butt, grip, procomp brake, barrel listed above and a two-stage cmc trigger. It seems pretty reasonable. I know the upper and lower are matched sets, each one made specifically mated. For a few bucks more, I can pick up some magpul flip ups and the seekins k20 angled grip then mount my sling(already on the bench). Gets me almost completely set for the rifle bays, minus those xm118 magpul magazines and rounds. I too was thinking about skipping the heavy buffer and seeing how it all played out. They swear that the 'tune-able' gas block makes the rifle very comparable to most m4's. Am just in this for a one rifle can-do go to setup. No, it will not be agile as a carbine. No, it will not stretch out like a bolt action. It is being geared for 50m-600m, with enough leg room to make a hit/miss gong shot out at ~800 yards for bonus points. I live in a very rural area, if it has not been guessed. Will be packing this thing across fields and through small forests when out-and-about. Excuse being, better conditioning for the biathalon and long days at multi-gun events. The barrel is fluted from the nut to gas block. Looks like a pretty decent bull contour, but after gas block it goes to a straight .750 inch diameter. Pound for pound, it weighs a bit less than my dad's dpms gas-piston(non impingement) carbine. That dpms has a standard contour 16" barrel and a 3-9 power second focal plane lens. It has a bit of kick even with a brake and is not exactly my cup of tea. Sure, it swings a little bit faster due to the shorter length barrel. I am not using this thing at less than forty yards. Less than that and my 1911 colt is out. The other end of it was, I had considered that Rainer Arms ultra-match 308 ambi-everything receiver set. It is high profile dpms. *shrug* but, no opportunity of applying for sponsorship or implied warranties with this route. The mega arms maten and the rainer arms both look nice. However, it seems odd to have an adjusting set screw for tension if they are billet receivers. =\ Thanks! Appreciate all the time and input guys/gals!

dislike double posting - failed to edit in time.. see: http://www.blackdawnguns.com/?product=black-dawn-bdr-10-308-receiver-set# I hate to throw out anything beyond this link. For certain reasons. They have an online review of a 243 build. When I was in the shop last week, it was hanging on the wall. Apparently, they built a few 308 rifles for shooting competition prizes and the such. According to a few of them, some group was doing a review on the 308 chambering but for some reason closed up and did not publish the review before ending their business? *shrug*

blue109, I hear it! I spoke with the local group enough to know their receiver set is basically a house spec dpms. unique flat top height for some reason about gas tube support. basically, it takes their own dpms barrel nut hand guard. any tube for dpms sr25 will work, just not line up with the top rail. if using the non railed carbons, etc etc it works just fine. I think the main purpose was, due to the 'look' it has. not like most of the generics. I agree entirely about the issue of cross compatibility. Also, with the weight. it adds up pretty fast. Any other help or advice about these things? I am really just trying to get explicit reviews and direct 'I did this, and it yielded that' type of responses right now. Seems like the 10oz slash buffer with standard bolt carrier group and tweaking this gas block should do about everything i want? What are some recommended brakes? I was leaning to that procomp by surefire. Cheap, looks reasonably well made and most 5.56 guys say the 'baby' variant works well. To hell with noise. It just means 'get off mah propertah!' ;-) Thank you all again, The Newb

I am aiming more for the combat build than anything. Something that will use xm118 style loads. Idea was a VCOG, a2 buttstock and grip with a floated tube. seekins k20 grip and a rhodesian sling from andy's leather. Just want it to be extremely reliable. Willing to settle for 1MOA from 100-300m and 1&1/2-2moa from 400-600m. Hoping a decent floated barrel with a dialed in hand load will hit sub 10" five round groups at 600m. What is the weight range we are talking here? The bare bones rifle with 'stock' dpms components weighed in at 9.3lbs - no mags or back up sights. I was estimating 15lbs with a full 25round pmag, vcog, metal magpul backups and the aforementioned accessories. Yea, I know - heavy. I also am aware of how 'weight' reduces recoil. Hoping it will be reasonably decent for accuracy, handling and longevity. I am not looking for a hunting rifle by particular.. Just something that with 180gr soft point handloads I can knock a deer or elk down when less than 300 yards away(little less than 300m). This is meant for as tight a group possible in run/gun scenarios. going to be using it for some biathalon stuff, multi-gun, etc etc. it will be lugged almost everywhere I go on foot. has to bang/boom in real world adverse conditions. rain, snow, sleet, cold, hot and dry. It will be used in rapid succession type firing. not worried about ten rings or anything else. I was figuring even with the 'extra mass' in a heavy buffer, that the operating properties of this gas system and bolt mechanism would provide minimal muzzle flip/rise. These rifles as a whole when using impingement tend to not buck. Thank you to everyone so far - any more inputs would be great! The newb

Hi, I tried posting a few times - for some reason I keep having troubles. keeping this short, for this try. So, I walked in to a local rifle builder's shop.. blahblahblah. they use a bunch of their own house brand dpms parts on a dpms/sr25 receiver set. it is their own spec cut, so the handguard/receiver height is proprietary. Seems ok quality. I know a few people whom have the 5.56&variants builds. How do I reduce recoil? I read about that XH slash buffer. worth the money? What type of negative or adverse effects/affects has it produced upon lower receivers? Mostly - does it damage the buffer detente bore? I want to reduce time between my splits on repetitive firing. This is for a heavy metal rifle class. Going to be throwing 175gr sierra matchkings. Trying to zip them faster than 2550fps while using H4895 or varget powders. The local builder wants to use their inhouse adjustable gas block. uses a 90* offset 'tuning set screw' that obscures/shrouds/limits the gas port. I guess with soft loctite and a general cleaning regimen it will be ok. Looking at 18" barrel(1:10 twist) with rifle length gas system and a rifle length buffer tube. That jp full mass high pressure special something or-nother $500 bolt carrier group set.. is it worth all that dough? They claim it is heavier than a standard dpms setup. How much heavier? If a carrier weight addition covers that extra mass, what is the real selling point? What are some potential negative side-effects of increasing all this reciprocating mass and reducing gas volume? I want 110% reliability in adverse conditions with less time between follow ups. Recoil reduction is an added bonus. Extra weight is of no concern, due to where that additional mass will be in the rifle. I foresee it better balancing everything. Anything I should know or be aware of? I would be grateful to many inputs of real experience. Please, no keyboard warrior jockey talk ok? Only input if you have a current functioning rifle, build them for a living or have sold yours in means for funding another build/paying for a second baby. Thank you, the newb! **edit** I somehow got this to go in site news and not general discussion.. *headshake* will an admin move this to the appropriate section please?
