Big Bore Barrel for your new “Thumper” AR-15

If you’re looking to sling serious lead through your AR-15, you’re probably looking at the big bore options for the caliber.  .450 Bushmaster is an excellent cartridge for big game, and Faxon Firearms has designed a barrel to give you the performance you need in the field, while retaining lighter weight for better handling.

This rugged barrel is constructed from 4150 Chrome Moly Vanadium steel, and finished with a nitride/QPQ finish for long life and resistance to the elements.

A Barrel Made for Hunters on the Move

Right away, you can tell that this Thumper barrel is different, with the “Gunner” profile barrel.  The taper towards the muzzle keeps the front end of your rifle easier to handle for snap shots, while retaining the weight behind the gas port to retain accuracy.

Since .450 Bushmaster is a straight-walled cartridge, this is a perfect part for building a semi-auto for  hunts where other cartridges may be restricted.
