AR-15 A1 10.3" CARBINE BARREL ASSEMBLY
BROWNELLS AR-15 A1 10.3 CARBINE BARREL ASSY 1-7 F-MARK M4 FEEDRAMP
Mfr Part: NONE At 10.3" this is the shortest version of our A1 profile AR-15 barrel assembly. Matching the exterior contours of commonly used carbine barrels of the 1960s through the 2000s, it’s ready to lend an extra touch of authenticity to your next build. Or install one for extra weight savings on a lightweight AR-15 SBR, PDW, or pistol - following all NFA rules, of course! Like all our Brownells Retro A1 barrels, the 10.3" model is machined from hardened 4150 steel, then MPI inspected to detect hidden flaws (so we can pull it from the supply chain BEFORE it leaves the factory) and given a hard black phosphate finish. It’s chambered for the modern 5.56 NATO cartridge, with speedy 1-7" rifling in the nitride bore, so the 10.3" A1 Retro barrel plays nicely with current-production ammo. Ordnance-grade 4150 chrome-moly carbon steel Durable QPQ finish 5.56 NATO chambered with 1-7" twist rifling Uses CARBINE LENGTH gas tube .070" gas port All NFA rules apply Up front, the 10.3" Retro A1 barrel has ½-28" tpi muzzle threads, ready to accept a "retro" flash suppressor or modern muzzle device / sound suppressor, and on the other end a standard carbine barrel extension’s already installed. Also installed: a 625" gas block/front sight base (F marked) with bayonet lug, sight post, detent, spring, sling swivel, Delta ring, barrel nut, weld spring, snap ring, and round handguard cap.
