Greetings all. I am new to the forum and wanted to share my build in progress on a gun I'm building as a tribute to my late grandfather who served during WWII on the pictured B-24 that was nicknamed "Tail Dragon". I am planning on laser engraving the upper with the image below.
I've built a few AR15s in the past without problems, but I've been apprehensive about getting into an AR10 style build for years because of the issues I knew I would likely run into with reliability and compatibility.
What I have so far:
Aero Precision M5 upper and lower
Geissele SSA-E FCG
Griffin Armament maritime receiver extension (AR10 length)
AR-SOB 4.9 oz buffer and 17-7 AR10 CAR wire spring
Criterion 16" stainless steel nitrided barrel, rifle length gas system, 15.25" gas tube, .094 gas port size, .750 gas block journal, ~3.03" from center of gas port to end of barrel
JP Enterprises High Pressure EnhancedBolt Assembly in .308 headspaced from Criterion Barrels
Magpul MIAD Gen 1.1 Grip
Magpul SL-S Stock
Strike Industries Anti-Walk Trigger & Hammer Pin Kit
On the way:
JP Enterprises FMOS Bolt Carrier (heavier than a standard LR-308 carrier)
Aero Precision 15" M5 Atlas S-One M-Lok Handguard
Wojtek Weaponry ARKTO .750 Set Screw Adjustable Gas Block
Radian Raptor Charging Handle (AR10)
Precision Armament EFAB .308 Hybrid Muzzle Brake
Ultradyne C4 Iron Sights (.308/7.62)
I've been reading a lot on these forums about properly balancing my recoil system with my gas system, and have tried to avoid mistakes to save myself the aggravation. I won't know whether there is an issue with my build until it is all put together, but I realize that given this set-up my rifle will likely have cycling issues due to the extra weight in the bolt carrier and the small size of the factory drilled gas port. Coming from the AR15 side of things, the rifle length 16" barrel seemed like an odd choice at first, but I have read of others who reported better reliability with that particular combination, so I figured I would give it a shot.
Any input would be greatly appreciated, thanks.
