edgecrusher Posted November 11, 2011 Report Share Posted November 11, 2011 Sounds great. You might want an Accushot monopod for the prs, a bi-pod, and start looking at glass. Quote Link to comment Share on other sites More sharing options...

Robocop1051 Posted November 11, 2011 Report Share Posted November 11, 2011 You'll need a pistol grip. I don't understand why you picked so many top shelf parts, then threw in some Spikes stuff. Spikes is ok for a budget rifle, but there are much better parts out there. I didn't know they made a LPK for the 308 yet. That SI Defense BCG is gonna be sexy, but unless you locked in a pre-order those cost $600 now. :oA Yeoung Mfg carrier w/ a JP bolt and a VTAC handguard would save you some money for other features, like a nice scope.

98Z5V Posted November 14, 2011 Report Share Posted November 14, 2011 Krieger 20" M110 SASS barrel, 1-12 twistGeissele Super Semi-Automatic Enhanced (SSA-E) Trigger - LARGE PINCouple questions about this part of parts selection - Why a 1:12 twist, especially when doing the M110 barrel, and Custom built Sniper model. What bullets do you plan to shoot with this, as a Sniper model? If you're shooting heavy, you should really consider something with a faster twist than a 1:12. Next - that LARGE PIN Geissele trigger is only gonna fit a Colt lower from the ban era - Nobody else ever made a Large-Pin lower. It will not fit your Mega lower. At all. Just sayin'... That SSA-E trigger is a very sweet unit, though - just put one in a build I'm doing. Very nice. Quote Link to comment Share on other sites More sharing options...
Robocop1051 Posted November 14, 2011 Report Share Posted November 14, 2011 I looked up your Spike's selections, and none of them are 308 specific. I'd ditch the buffer and spacer and go with a standard heavy buffer. Also, your Spike's Enhanced LPK is going to need 308 take down pin, pivot pin, and a bolt catch.

bakerk Posted November 15, 2011 Report Share Posted November 15, 2011 Mega matched sets come with the take down pin and pivot pin. The only thing in addition to an AR15 LPK needed for my Mega build was the bolt catch. Good choice on the Mega, Love mine. Quote Link to comment Share on other sites More sharing options...
98Z5V Posted November 15, 2011 Report Share Posted November 15, 2011 That Spike's T3 buffer weighs in at 5.4oz. An Armalite AR-10 rifle buffer comes in at 5.4oz, and an Armalite AR-10 carbine buffer is also 5.4oz. That Spike's T3 (and spacer) will be good for a rifle-length receiver extension build - at least as good as any other standard .308 rifle or carbine buffer. After shooting it a little bit, you might find that you want more weight there, and a Tubb CWS could help you out, if that's the case.

SOCOM1 Posted November 19, 2011 Author Report Share Posted November 19, 2011 No, you did not scare me off. I have been working A LOT (which is what is funding this build). I have also been doing some research.Thanks for letting gme know on the trigger pin size. I have found the correct one for my build.I also have decided to use a different handguard. I really like the look of the KAC M110 SASS, so I am considering the KAC URX or something similar, open to suggestion here. Also, the barrel is a 1:10 twist. Sorry for the typo.

98Z5V Posted November 19, 2011 Report Share Posted November 19, 2011 The URX has a proprietary barrel nut, which requires a special barrel nut wrench for installation. That barrel nut wrench is only made by... KAC. It will cost you more than $250 for the barrel nut wrench. Example:http://www.operationparts.com/KAC_Knight_s_Armament_URX_Barrel_Nut_Wrench_p/20495.htmSince you specified "or something similar," I'd start looking at what looks similar in your eyes - it's all up to you. Another option, if you're set on the URX, is to buy it from a vendor that will install it for free, for you. You'd have to ship them the upper, but they install your rail. One company that I can think of that does that is The Gun Gallery, in Florida. I like that look, too, but I went a different route - Troy MRF-308, with the KAC panels on it. Had bags of those panels stored away, anyway. Here's how mine ended up looking:Thread:http://308ar.com/forum/dpms-lr-308-general-technical-discussion/lr308-self-build/ Quote Link to comment Share on other sites More sharing options...
moagm316 Posted November 26, 2011 Report Share Posted November 26, 2011 I am planning a build soon. I was looking towards the SI Defense Billet Matched set coated in Nickel Boron. On the other hand I want to go with a Noveske Barell. Do I have to go with the MA-TEN to use the Noveske? If I do go with the Noveske I will just send the MA-Ten out and have it NIB Coated. As far as the bolt and BCG what do you all think? Quote Link to comment Share on other sites More sharing options...
Robocop1051 Posted November 27, 2011 Report Share Posted November 27, 2011 Wmdguns.com does very affordable NiB coating. As far a BCG's are concerned. I think how you plan to gas your rifle is important first. If the rifle is ever going to have a MIL/LE duty use, get a standard gas block. If competition/paper poking is your game, go for an adjustable gas block. I don't believe in precision pistons. A good sturdy BCG is perfect for duty use. Fulton or YM make good clean gear. SI Defense is really nice, but twice the cost. Then add a CWS, CS flat spring and an upgraded buffer. Competition and bench shooting, I have to say the JP "Low Mass" BCG combined with a good spring and controlled gas. I would stay away from heavy buffers, but I might consider a hydraulic buffer. Since precision is your aim, and not combat, I would go for a good heavy (Cooley?) break. Quote Link to comment Share on other sites More sharing options...
moagm316 Posted November 27, 2011 Report Share Posted November 27, 2011 I was actually looking at the SJC Titan for my brake. I want to go with an 18" Noveske Barrell. Do I have to use the MA-TEN with this barrell or can I use the SI Defense? It says that the Noveske is only for use with AR10 uppers, but the SI Defense is built with a DPMS height upper. What gives? I am definitely going with the factory installed low profile gas block. Quote Link to comment Share on other sites More sharing options...
moagm316 Posted November 27, 2011 Report Share Posted November 27, 2011 I definitely want a Nickel Boron Coated bolt and BCG. Any suggestions? I want shot peened, MPI inspected high quality bolt. Quote Link to comment Share on other sites More sharing options...
Robocop1051 Posted November 27, 2011 Report Share Posted November 27, 2011 SI Defense is DPMS/KAC compatible. The MA-10 is both, Armalite or DPMS, but you can't mix and match parts. If you get an AR-10 barrel, then you need an AR-10 bolt. If your heart is set on a Noveske barrel, you will have to build an Armalite compatible rifle. The BCG you described is only made by SI Defense (hence, DPMS only). I don't know of an Armalite equivilant. The SI-D BCG IS $600 now. You can get similar BCG's and send them in for NiB, TiN or hard chrome coating... All for much less. Quote Link to comment Share on other sites More sharing options...
moagm316 Posted November 27, 2011 Report Share Posted November 27, 2011 Any suggestions for Bolt and BCG? I will definitely send it to get NIB coated then. Quote Link to comment Share on other sites More sharing options...
Robocop1051 Posted November 27, 2011 Report Share Posted November 27, 2011 Honestly... I say go with a standard Armalite AR-10 BCG. Whoever you send it to will strip the parkerizing off and then re-coat it with the NiB. Quote Link to comment Share on other sites More sharing options...
moagm316 Posted November 27, 2011 Report Share Posted November 27, 2011 Ok I am really confused now. Some have said that the Noveske Barell will fit the SI Defense or the MA-TEN. ALso if my lower says that it is compatible with DPMS why cant I use PMAGS with the Noveske Barrell and Armalite Bolt? Quote Link to comment Share on other sites More sharing options...
moagm316 Posted November 27, 2011 Report Share Posted November 27, 2011 Ok here is what I found out from Mega on their site."Magazines… take your pick. Any SR25/DPMS compatible magazine such as Magpul, Knight, DPMS, CMMG, and C products.Bolts & BarrelsDesigned to accept any AR style .308 barrels and bolts*. This means you can use your AR10/Noveske or SR25/DPMS components.*We recommend using the same manufacture for your barrel and bolt. As always assembly should be done by a qualified gunsmith, using the proper head spacing gages." Quote Link to comment Share on other sites More sharing options...
imschur Posted November 27, 2011 Report Share Posted November 27, 2011 To clarify for others. The uppers dont care what barrel you use. Match the barrel extension and your bolt. Please dont mix bolts and carriers stick with one brand 100% for the BCG. To me it's a bad idea to use an Armalite carrier with a DPMS bolt or vice versa. Someday if the weapon is sold it could be problematic for the new owner. Quote Link to comment Share on other sites More sharing options...
moagm316 Posted November 27, 2011 Report Share Posted November 27, 2011 Agreed. I will be using a Noveske Barrell with an Armalite Bolt coated by WMD Guns in Nickel Boron. Quote Link to comment Share on other sites More sharing options...
