High power AR-15 upper in .243 WSSM. This upper has had forty or less rounds through it, bore is in excellent condition.
This is a rare find. If you’re considering this upper receiver you know and understand the history of the .243 WSSM. It is one of the flattest shooting rounds but has been relegated to use by reloaders as new ammunition is no longer being manufactured.
This flattop A3 upper receiver comes complete with charging handle, bolt carrier assembly, aluminum tubular free-float handguard, Picatinny-style rail gas block and target crowned muzzle. The 24" button rifled Ultramatch barrel is chambered for 243 WSSM with a 1 in 10" rate of twist. WSSM uppers do not come with a brass deflector or ejection port cover. Ready for installation onto any standard AR-15 lower receiver. Includes one 7-round magazine.
