This may be the RISR ??? Here is a link; http://www.laruetactical.com/larue-tactical-risr-ctr-combo Had some curiosity about this item myself.

Post a picture so I know which one it is, if it is the style with the three adjustment notches I'll give you $75?

The Lee die is available separately for $20 or less, well worth it!

I had issues with adjusting the crimp till I got a Lee factory crimp die, it uses a different collet system that doesn't shove the mouth down. My previous reloading experience had all been with neck sizing and no crimp for bolt guns. I had problems setting the crimp on the the hornady die, just like Ripper stated I was bulging the shoulder. The Lee is much more forgiving, this along with using a case gauge and I haven't had an issue since. I use a dummy round to check my setting but never check all my live rounds in the weapon, just the gauge.

Is that checked in a case gauge or just a comparison of measurements? Case gauge is a must for AR's

I've had no issues using Hornady FL die reloading for my AR-10. I do run the case into it twice, not because I've had a problem with one pass but because I'm anal............. There are tolerances for chambers and dies alike, the right combination of a tight chamber and a loose FL die may not work, I was lucky and my combination works fine while not working the brass quite as much as a SB die. What dies are you using? Consistency in your procedure is a must as well. I've never heard of a chamber "swelling" enough to make that kind of difference <dontknow> If you were having issues after firing a mag or so I'd guess a build up of case lube but the opposite just doesn't sound like a chamber issue but a case size issue. Do you check the reloads with a case gauge?

Stay safe, hope there are some youngsters out there with you so that skill and determination can be passed on!

I appreciate the first hand info, that's why I love this place, you get the straight shitt here! Odds are I'll go the ACS route and if it feels light in the azz I'll put some lead in that little compartment I've never found a purpose for <thumbsup>

I've got an extra buffer from my Sig PM400 that I put an H3 in and have an H2 in my Armalite M15 so I have an assortment to try from then. Guess I'll get the tube and spring first then see what works out. I have an ACS on the M15 so maybe there is something to be said for consistency. Is the UBR much heavier than an A2 set-up? I was thinking the extra weight might help balance the rifle but I sure don't want the balance point going too far back??? The price on the UBR does make it easier to talk myself out of it.........

No F-book for me, couldn't get past the user agreement! I frequent two other sites, SigTalk and AR10T and the 10T site is about dead. I do look on barfcom for info like reviews and specific issues but seldom find what I'm looking for due to a lack of patience, too much crap to sort through. I signed up here in 2011 but didn't really post anything till a little over a year ago...........stayed pretty broke since then <thumbsup> THE BEST enablers on the net are right here!!!!!

Thanks guys, after sleeping on it I can live with the gap. Time to move forward on the build. I spent several hours this morning looking at gas blocks and reading here, still not 100% sure what way to go but strongly leaning to the adjustable. With the rifle length gas system on the 16 inch barrel it looks like I would only need an adjustable gas block if I go suppressed. I'm hoping I get that opportunity some day, it was real close this year so there is hope and I don't want to switch out the block later if I can get a can. I didn't really like a few things about the Syrac adjustable, the rear facing screw and the ball and spring setup look like a weak spot for corrosion , fouling, or breakage. I found one I think I like; http://slrrifleworks.com/index.php?route=product/product&path=57_103_104&product_id=386 It is a little pricy but then it is the only one I have found with the features I like, adjusts at the front, no small parts, easy to clean, and solid adjustments I can keep track of for tuning to different ammo. Have I overlooked any others with these features??? The last decisions I need to make are stock and buffer system. I'm thinking about using the Armalite carbine tube, spring, and buffer but still haven't ruled out a UBR stock so I haven't ordered it yet. If I go the UBR route I had thought of getting the buffer from Slash but I'm a little concerned that the rifle length gas on a 16 incher might not have enough umph to push a heavy buffer, any input there would be appreciated??? I've read lots of conflicting info on what buffer to use with the UBR? I may just build it using my Armalite rifle set-up for now so I can at least get a function check sooner than later. Whoever said "The best things in life are free." never built a 308AR!

Great link for the sights Brother :hethan: he does Sigs as well! :2nd:

Don't mind me....I'll catch up eventually ::)

I've did the SAC museum in Omaha, NE several years ago( they had a Blackbird ^-^ ) and the National Naval Aviation Museum in Pensacola last year. Both are smaller but still well worth the visit!

That is exactly what I didn't like about FrogLube! My 1911 would be fine, dry and grippy, until I ran a few mags then the stuff was oozing out all over making the gun way too slippery.

Guess I didn't realize there was a pencil spec for 308 AR's <dontknow>

I am a bit anal about this sort of thing.........I imagine once I can get 5 rounds under an inch at 100 yards I'll start to forget about the "big" gap. <thumbsup> I'm betting the barrel nut will hit the 35ftlbs by the next notch so the look shouldn't change much at all. Guess if it does open up more than I can stand I can go to the local machine shop and have a touch shaved off the top rail end. It does have a knurled barrel nut so with that, the loc-tite, and the 45 inlbs called for on the two bolts the rail should stay put. Another months gun budget and I should be shooting this thing!

The basic purpose like most of my weapons is to defend myself and my family from a tyrannical government or other threat if needed. Hopefully coyotes, steel, and paper is all it ever gets unleashed on. For the gas block I'm thinking an adjustable, lightweight isn't the prime concern, I can't run so I don't need to move fast with it.

I did get it real hand tight to line it up the top rail so I'll have to torque with the wrench to the next notch. Looks like maybe I should just ignore the gap and get a gas block ordered aye? Who makes a good one, I've never messed with them?

Curious how you decided how much to shave? I'm afraid I would develop a flinch from not knowing how much was too much.

Welcome from Iowa, the pig capital of the world! and yes it smells real good here...........

Must be the one I heard the news report on........had to have been some BIG sparks!

Well I'm off to a rough start....first all the issues with the barrel being shipped back and forth and no sooner does that get squared away and I'm looking at a rail that has a poor fit; This is an MI SS rail for an AR-10, I assumed with the Armalite threads that an Armalite rail would fit right. I haven't torqued the nut yet as it sits in the picture so the rail is going to get further from the notches in the nut while the top rail is already hitting. Am I doing something wrong with the installation? This is my first big bore build and first upper so I'm not certain what to expect but I sure expected a closer fit between rail-nut-and receiver. Do I need to back up and get a different rail, like the Matrix I should have gotten to start with? <dontknow> If this is a common occurrence or normal fit then please tell me to get over it and carry on, I tend to be a little over critical of things I build. If I do need a different rail all is not lost as I have an AR-10 that needs a FF rail. I spent a bunch extra getting rails, covers, and QD swivels with attachments just for this rail so selling it would bite! I was going to throw on an A-2 stock I have and try to function test the bolt tonight but I decided this was enough for one evening :-[ I still need to decide on a gas block, I'm thinking I'll go with an adjustable, I'm keeping up hopes Iowa will join the ranks of the sane and allow suppressors soon. What are some suggestions for a quality adjustable gas block?

That's the problem those types always have, friends and family already know the truth behind the "emergency" and strangers seldom give a schit.

I wouldn't give up my Atlas, locks at 45 forward, 90 and 45 to the rear. I have never had my hands on the GG&G, might be my next bipod. There will be some good sales coming for Labor day, might be worth waiting just a bit longer if you end up buying new.
