    What determines brass ejection angle/position

    Try a heavier buffer weight, and a Tubbs 308 recoil spring... retune Adj. GB as needed. Ultimately, cyclic speed can make a difference.

    Aero Precision LR308 Upper w/out BCG, or Pricier Complete Upper?

    You can always try a complete Upper from Aero. If it doesn't shoot to your expectations , at the very least you now have all the parts needed to swap in a different barrel. If you decide you want a "better" barrel... Criterion's don't cost much more and have always done good for me. Have you...

    New Sniper Team, what ammo for LMT 308

    Thank you for the info on the TTMK, I have always wondered about the "whys" of that bullet "line". Any online info I could find lacked ANY meaningful answers. And , as mentioned I have wondered for years... so I am now breathing a small sigh of mental relief, Lol. Again, Thank You.

    Aero Precision LR308 Upper w/out BCG, or Pricier Complete Upper?

    Some of those older DPMS's can be quite accurate with heavy profile barrels. I would try some "better" ammo first , prior to a 6.5CM upper.

    Looking for 18" or 20" Barrel Advice in 6.5 Creedmoor

    What is your budget for the barrel ? IMHO, buy the best barrel you can afford, otherwise you'll just spend the money on ammo, trying to make a cheaper barrel shoot to your expectations. Looking online, it appears your barrel might weigh around 82ish oz's ( 5.13 lbs ) ... so a Criterion barrel...

    Aero m5 6.5 creedmoor build

    No odd damage to the rounds being cycled via the gas system being used ? Everything good n' tight enough for the gas operation ? Upper to lower fit maybe ? And at the risk of sounding like a dip_shit... turning off the gas made your LFAR a "bolt" gun, with very little moving parts... so the...

    6 ARC Gas port erosion

    Judging by the lack of copper buildup, at the gas port, I don't know if the bullets are deforming. And those groups seem pretty danged good to me, especially given the various charge weights , powders and bullets. I would carry on.

    Aero m5 6.5 creedmoor build

    No offense intended at all, but is this your first LFAR ? Large Frame AR's require a "different" shooting style compared to a AR15. It is hard to describe, but follow through is very critical to shooting precision groups. Also, the added mass of the recoil cycle, amplifies any thing you can do...

    Popping primers.

    As mentioned, clean the chamber and bore thoroughly. Packing oils / rust inhibitors left in the FN barrel are quite possible.

    New Purchase?

    As far as the SOLGW comments... be careful as to which barrel you might get. As far as my feeble mind can attempt to understand, some match barrels are Ballistic Advantage, and some are BHW. Poking around a little, some links say 1n8 twist, some say 1n7. The barrels that say .. 6mm ARC 416...

    Yeah... I tried it as well... basically the JHP version pales in comparison.

    Magazine v. Accuracy

    And danged cheap !! The cheap / accuracy aspect, would help new shooters have confidence. ( Not to mention soften the blow to my wallet ! ) I never did see it in any catalog, online or otherwise. I wish , Federal would produce it again with the same accuracy. ( Never gonna happen... but, I can...

    6.5 Grendel barrel suggestions

    FWIW... The only reason I think some of the SOLGW barrels are BHW, is because of the specs on the webpages being very similar. SOLGW specs... specifically, "3 groove polygonal rifling, 1: 9.73″ twist rates" ( Odd twist rate ? ) And frankly the odd, twist is what made me poke around and look a...

    Ok... now that it is a Bolt Action we are talking about. That changes my answer quite a bit ! Lol

    Magazine v. Accuracy

    Load to the length your magazine will accept. Chasing the lands on a AR firearm , will only frustrate you. And while you may have seen some of your reloads shoot tighter groups... not being able to load a full mag and getting it to function 100% , is self defeating. FWIW, I have seen numerous...

    6.5 Grendel barrel suggestions

    I have been hesitant on SOLGW barrels, because a lot of them were Ballistic Advantage barrels... But, some now "appear" to be Black Hole Weaponry barrels. The problem is... I would be willing to try BHW barrels.. but not BA barrels. And, I can't always Identify which one is made by who ? Given...

    Barrel extension material failure?

    How many rounds thorough it ? I don't know if those would concern me much. it kinda looks un-finished, or not fully polished ? However... in the pic, the marks at the bottom middle of the feed ramps ? Is it just the lighting or are the rounds tips smacking that ?

    First AR10 build, what did I do wrong?

    I would round / smooth / polish the edges of the ejector. Clean out whatever that sliver is in the bolts FP aperture hole. Polish the feed ramps. Rifle lower w/ 5.6oz buffer ? Carbine lower w/ 3.8oz buffer ? ... any way, the OEM buffer weights on both are what I would consider LtWt, For that...
