    I bought this Armalite A4 around election time because I though Hillary was going to win. I chopped the barrel down to 16 inches with the RLGS it's a very soft shooter. It also has a adjustable gas block, Tubbs spring. Also a Franklin Armory binary trigger. It runs like a top but it's a handful on binary...

    I killed a 200 lb hog with it last week in Tennessee. I have a YHM Resonator-K in jail for her...

    I bought this one NIB from a friend in 2006. It was your typical AR-10T with a 24 inch barrel. This thing was scary accurate with the original LW barrel. I finally burnt out the barrel and I put on a new 18 inch LW barrel but it's nitride. I have not had time to do proper testing for accuracy yet but from what little I have shot it, it shows promise.

    This was my first AR-10 build. I set out to build a battle rifle. It was a fairly expensive build (about 3k without optics). 16" BSF carbon, Smoke Composite handguard, Spikes Tactical NB BCG, WIlson Combat AGB, and PSA 3.5 match trigger are the notable additions. I was trying to make it as light as possible without sacrificing shootability and the ability to shoot it suppressed. It worked out to 7.8lbs without optics. I didn't take weight from the BCG which I could still do but they cost a pretty penny. WIth the optics I have on it presently it weighs in at 10.2lbs. It shot well it's firs time out. I put some old 175gr miltary ammo through it that was too hot and I was a little worried cause it blew a couple of primers. I switched up to some 168gr AMAX that I loaded with 43gr of 4064 in some LC brass and it shot under an inch with and without supressor. I was pretty happy. Does it look like a battle rifle?

    Aero M5, Prs gen 3, MI 3.5lb single stage drop in trigger, Ballistic Advantage 308 16" mid gas, DD 7.62 lite 12.0" rail, Seekins adjustable gas block, Tbac ultra 9, Warne skyline 1.54 0moa mount with swfa 5-20x50. Plan is to shoot it, shorten it to 16" total with pin/weld brake for omega. Then custom barrel to the length I like out of that. Want to put a Mark 5hd scope on it also.

    STOP ! OK, I've had enough. I want to sell some stuff I haven't shot for a few years and buy or build a AR-10.

    I want to replace my Sako TRG-22 I don't shoot anymore. Looking for help for a 16-18 inch barrel AR-10 build that can shoot 1/2 (ish) MOA with premium optics.
    I like my Hk MR556 gas piston rifle over my AR-15 DI guns only cause of the easier clean up and put up.

    Does Georga make a piston GAP 308?

    Sorry for the intrusion, but I need help on a build / buy

    wrong thread to be posting in. you really should start your own thread, or post in the GAP thread if you really want help or assistance. JMHO.

    So this is my second .308 build. I wanted to see what a pistol version would do. Weighs in around 7 lbs without optics.

    Build sheet:

    PSA lower
    Gibbz Arms SIde Charger upper
    SSA-E trigger
    Ballistic Arms barrel
    JP Enterprises LMOS (Gosh these are expensive)
    SLR
    Solo handguard
    Superlative Arms adjustable gas block
    SBA-3 Brace
    5.6oz buffer with heavy spring
    Lantac Dragon SIlencerCO ASR (I'm hoping this tames the muzzle flip)

    I've limited experience in building these machines but this one flowed together after the AR15 experience and my first 308 build. Does anyone else have a 308 pistol? If anyone has any experience with the Saint Victor 308 (28" OAL) please PM me, I've got some questions.

    Any experience with Faxon 308/6.5 barrels here? Friend of mine is trying to convince me to build a large frame gasser and I am intrigued by their lighter weight profiles that Faxon puts out.

    Is there a tested recipe for building large frames? It seems like a ton of trial and error compared to a small frame.

    I had pretty good results with one of their 308 barrels, .75-1 moa with good ammo. I would not recommend their 6.5 barrels right now. The feed cone on their barrels is too small and a lot of the 6.5 projectiles I tried, especially secant ogives, will jam below the cone. 147 eld-m would chamber, but would damage the tips on the way in, 140 hybrid targets would completely jam up. I don’t know if they’ve done anything to fix this issue yet.

    Thanks for the reply, slightly leaning to 308 anyways.

    Could one be reliably served with an Aero M5 set/Criterion or Faxon barrel/JP SCS/Aero BCG?

    Any other BCGs to recommend?

    Those are all good options, Faxon also has contract overrun .308 BCGs on sale right now which I’ve heard are pretty good. I have one but am waiting on my barrel to show up before I can use it so can’t comment on how it performs.

    How would that general list compare to a LMT/KAC?

    Obviously its not one of those, just trying to get a frame of reference. Kinda looking for a “BCM” grade large frame rifle.

    What’s your intended use for it? Homebuilds can be finicky and require some tuning. If you want off the rack “BCM” grade, I would look at the Sig 716, Seekins SP10, SCAR 17S. Plenty of great rifles built off the Aero receivers though

    I have a Faxon 6.5CM barrel in a Aero M5 receiver, have only been shooting factory ammo. No problems at all with feeding, with various types of factory ammo.

    General use carbine from 50-600 yards for when something a bit larger than a 12.5” 5.56 is needed. This is not an ”HD” or “truck” gun. Think large frame recce rifle and it may give a better image of what I’m wanting to do.

    The Seekins is a bit into the SPR type direction. The Scar 17 with some extras would fulfill the purpose quite well, but I’m cautious due to the seemingly lack of spare parts if something were to break. Not to mention the price tag.

    At the 17’s price point, I’d probably just get a KAC SR-25 CC.

    I don’t mind too much tuning, just want it to be able to run 147/150gr and 175/178gr class ammo reliably.

    @PBWalsh just a suggestion, you should start a thread with all these questions and discussion. After you've completed your build, come back and post your masterpiece in this Pic & Build Info thread. JMHO, nothing more.

    Happy Thanksgiving! (y) (y) (y)
