This is a NEW, 20" Govt. profile AR 15 barrel chambered for .22 lr. Includes stainless steel bolt assembly. This will install into any upper to create a dedicated .22lr upper assembly. Includes 1 ea (slightly used) Black Dog 25 rd magazine, barrel nut, delta ring assembly and round hand guard cap. This is a $425 value. All you need to finish this upper is an upper receiver (as low as $40), charging handle and a gas block to mount the hand guard cap to (this is a blow back operated action, so no need for gas tube). Sell for $350 cash, or see trade interest below. Alternately, I can add a new, Midwest Industries rifle length quad rail hand guard which is a $160 value or cash to make up any difference Trade Interests: H&R 999 .22lr revolver Ruger 22/45 lite Marlin Lever Action rifle (.22lr or centerfire) FTF in Tigard, Newberg or McMinnville.
