Selling my 300blk upper. PSA upper receiver, Ballistic advantage 6” pistol gas 300blk barrel, gas block and tube, Rearden minimalist Plan B suppressor mount and AT3 10” SD mlok handguard for suppressors 1.625” OD and under. Runs subs suppressed no issues, supers too but obviously a tad over gassed with a can. I’ve got videos of it running too. No BCG or CH included but will ship with an H1 buffer and sprinco yellow spring. No trades on this one.
