A customer sent me this photo of his fine Bison Armory based rifle. The 22″ 6.8 can reach out there. The customer got the last of our Mega billet side charge upper receivers. Mega is gone and there won’t be any more of these fine upper receivers. I built all my long-range AR-15 rifles with these SBU side charge receivers, they are bulky and burly and absolutely perfect for the job.
