450 Bushmaster for the Mauser Rifle in a Sporter Profile for Large Ring Actions

Please visit our new web site at www.rhinelandarms.com to place an order, these are in stock and shipping. 

This is part of our We Goofed sale, we were supposed to order 45acp barrels but accidentally ordered these and we have way too many of them so were blowing them out.

If you are looking to customize your bolt action into a hard hitting brush rifle or surplus ammo shooter we have a barrel for you. All of our barrels feature the Savage style lock nut system and full-length chambers, so anybody with some skill can re-barrel their rifle. Our barrels are air gauged and feature extremely tight, full-length chambers. All chambers are cut using SAMMI spec reamers. Our short, fat barrels are built for hunting in thick brush for hog, etc using suppressors for creating a thumper scout rifle. These barrels are made thicker than the .45 acp for the higher pressure and they also feature a high precision chamber.

5/19/2026-please note the muzzle threads on these barrels are 5/8-24. The current supplier tends to get a burr or rolled edge on the starter thread. We try to remove these but if we miss it, can be easily removed.

The barrel profile in the picture is not correct. The picture is a light bull barrel. This is for Sporter profile barrels.
