Chambered in .450 Bushmaster with a 16-inch parkerized heavy Bear Creek Arsenal barrel with a 1:24 twist and a carbine length gas system. We suggest Hornady 250 grain FTX ammo for maximum potential. The Thumper shines in dense brush and for people who do not like tracking their animals. Available with Cerakote E-100 blackout option for the inside of the Upper Receiver.
All of our Upper Receivers work with standard AR-15 Lower Receivers
