The Zel Custom Tactilite T-1 Ultralite 50 BMG AR upper converts any AR lower into a powerful, long range single shot rifle capable of great accuracy. The 50 BMG upper reciever is machined from a single billet of 4140 chrome-moly steel hardened to Rc 42-45 and Parkerized with a black CeraKote topcoat. The 4340 heat-treated steel bolt is a two-lug design and has an easily manipulated bolt handle. The MIL-STD 1913 Picatinny quad rail is 7075 T-6 aluminum (most rails are much weaker 6000 series). The T-1 Ultralite 50 BMG AR upper comes with a choice of 24″ or 29″ Mossberg chrome-moly steel 8 groove, 1:15″ twist barrel with USGI dimensioned chamber for maximum reliability. An integral muzzle brake is fitted to the Tactilite AR 50 BMG upper barrel to reduce recoil.
