MBZ Firearms

Buy the rifle, or just the upper assembly for your AR-15.
Swap barrels, calibers and lengths, just about as often as you want.

You change the barrel yourself with no gunsmith, so one MBZ-15 can shoot whichever caliber suits what you have planned that day. Barrels come in various lengths and in 5.56 NATO, .223 Wylde, 300 BLK, .350 Legend, 6.5 Grendel and 6mm ARC, with more on the way. Some calibers take their own bolt or magazine, which you swap just as easily.

Do you hunt?

A 6.5 Grendel or 6mm ARC barrel for deer, a 5.56 barrel for coyotes, and the same trigger and the same optic in your hands all season.

House and range?

A 5.56 barrel for the range, a 300 BLK barrel with a suppressor for the house, and any other caliber you want, all on one rifle you know and clean.

On the road?

One case, one rifle. Two barrel kits, three, five or ten, it makes no difference: you shoot whatever you want with a single rifle, and it takes one slot in the safe.
