Product Overview
Picking a barrel for an AR-15 usually means working out the gas system length, gas block size and muzzle thread yourself, then installing it like a gunsmith, with a torque wrench and an armorer's wrench. With MBZ, you just choose the caliber and the length, and the kit ships complete with the barrel ready to swap.
Every MBZ Barrel Kit is built by MBZ in Evansville, Wisconsin, and ships ready to install.
5.56 NATO 16" HBAR barrel, delivered with the MBZ Barrel Adapter mounted, ready to swap onto your MBZ-15 or MBZ Complete Upper Assembly.
What's in the box
- Ballistic Advantage barrel, 5.56 NATO, 16", HBAR profile

Runs on
Runs on the standard MBZ-15 bolt. Uses 5.56 / .223 magazines.
How the swap goes
Take any accessories off the handguard, unscrew the handguard, loosen the Adapter with the spanner wrench and pull the bolt back slightly to unlock the barrel. Slide the new barrel in, release the bolt, snug the Adapter with the wrench and give it a light tap, then screw the handguard back on. No torque wrench, no gunsmith. Recheck the Adapter when you clean the rifle. Your optic stays on the receiver.
Good to know
This barrel kit fits the MBZ threaded upper receiver only. It does not fit a standard AR-15 upper. Estimated kit weight: 48 oz, to be confirmed once a packed kit is weighed.
