.300 black out Xproducts side charging complete upper with A2 birdcage. The barrel length is 12.5" and w/ the A2 birdcage is 14.5" from the upper receiver. This is a non-reciprocating upper (i.e. It won't hit your face!) with a Xproducts viper handguard. This is truly a unique setup and I am selling to fund my AR-308 build. Please email or text 661-333-6807 for more information. Looking to get $500 OBO
