AR15 Custom Built Dual Caliber 5.56/300 Blackout for sale in Texas

$800.00

Used rifle with two uppers, one bolt with both uppers working on the single lower. They are both 16 inch barrels. The 5.56 is a 1:7 with NATO chamber and carbine length gas system and the 300 Blackout is 1:8 with pistol length gas system. The 300 functions with subsonic ammo so if you have a suppressor it will function with subsonic ammo. Both barrels are head spaced to the same bolt and shoot a repeatable and realistic 1.5 MOA with the right ammo. The free float forearms have quick detach sling swivel sockets front and rear and the muzzle brakes are Bushmaster Izzy style.
It is built on a Bushmaster XM 15 lower with an ALG single stage trigger with a 6 pound measured pull and ambidextrous selector switch. It comes with 2 new magazines and a green and a tan single point sling. Both barrels have less than 200 rds through them. The grip is a Tango Down battle grip with waterproof storage in the bottom. It also includes the double sided hard case.
I'll knock $200 off for a partial trade with a bolt action .22 rifle.
I can ship to FFL's if you want to pay shipping or there is free local pickup in the DFW area.
