Luth-AR BA-F20SS7CG A1 Slick Side Mod RTR Upper Receiver

Luth-AR A1 Slick Slide Retro Complete Upper Features The Luth-AR A1 Slick Slide Retro complete upper is built around a 20 chrome lined barrel with a 1:7 twist rate giving shooters the stability needed for longer range work while the chrome lining extends barrel life under sustained use. The 5.56 NATO chambering keeps ammunition widely available and affordable for range sessions and training alike. A manganese phosphate finish on the barrel resists corrosion and wear while holding the period correct dark appearance collectors and retro builders look for. The non-F marked front sight base at .625 diameter further reinforces the early-pattern look this upper is designed to replicate. The triangular A1 charging handle provides a distinctive classic profile while still cycling smoothly and reliably with every stroke. The A1 handguard uses rivet-attached heat shields rather than modern polymer liners maintaining the exact historical construction method while still dissipating heat and offering a firm secure grip under rapid fire. An early A1 duckbill flash hider caps the barrel reducing visible muzzle flash while preserving the low-profile silhouette typical of these early rifles. Finished in OD Green this upper assembly is a complete drop-in option for any retro build project for sale at ARMSAGORA.
