RUGER AMERICAN GEN2 450BM 20″ GM 3RD

The Ruger American Gen2 in .450 Bushmaster with a 20-inch threaded barrel and GM 3rd stock is a purpose-built straight-wall thumper for hunters who need ethical energy inside 200 yards, paired with Ruger’s proven controlled-round feed action. This ruger american gen2 450bm 20” gm 3rd delivers sub-2 MOA accuracy out of the box with factory loads, and the Cerakote finish means you can drag it through a swamp without watching the steel rust. Per Ruger specifications, the barrel is cold hammer-forged from 4140 steel, then Cerakoted inside and out for corrosion resistance that holds up to hard use. If you’re building a dedicated brush gun or a straight-wall deer rig for states like Ohio, Michigan, or Indiana, this is the production rifle that skips the custom wait times.

Key Features

• Cerakote Barreled Action — Why it matters: The factory-applied Cerakote eliminates the need for aftermarket coating, sealing the barrel and receiver against moisture and salt spray so you don’t chase rust after a wet hunt.
• Threaded Bolt Handle with Stainless Bolt Body — Why it matters: The threaded handle accepts aftermarket knobs for faster cycling under gloves, while the stainless body resists galling in cold or humid conditions where blued bolts bind.
• Three-Position Tang Safety — Why it matters: The center position locks the bolt but allows you to load the chamber with the safety on, so you can top off the magazine without flagging your line or risking an AD.
• Removable Comb Riser — Why it matters: The adjustable cheek piece lets you align your eye with high-mounted scopes or red dots, eliminating the need for a custom cheek rest or foam pads.
• Power Bedding System — Why it matters: Ruger’s integral bedding block free-floats the barrel and locks the action into the stock, maintaining consistent bedding torque even after disassembly for cleaning.

Who It’s For

This rifle is built for the straight-wall hunter who wants a production gun that shoots as well as a semi-custom. If you hunt deer or hogs in dense cover where shots rarely exceed 150 yards, the .450 Bushmaster delivers 2,200+ ft-lbs at the muzzle with 250-grain loads. It’s also for the reloader who wants a threaded barrel to mount a suppressor or muzzle brake, keeping recoil manageable in a 6.6-lb package. The Gen2 updates make it a viable option for the precision shooter who needs a hard-hitting backup rifle for short-range steel or pig hunting.

Pros and Cons

Pros

• Sub-2 MOA accuracy with factory ammunition, verified by multiple independent shooters
• Cerakote finish on the entire barreled action, not just the barrel
• Threaded bolt handle and stainless bolt body reduce maintenance
• Removable comb riser fits shooters with various scope heights
• Price point $607.20 is competitive with Savage Axis and Mossberg Patriot straight-wall options

Cons

• Stock is still polymer with a flexible forend, which can affect consistency when shooting off a bipod or bag — you may want to upgrade to an aftermarket chassis for precision work
• Magazine capacity is limited to 3 rounds from the factory, which is adequate for hunting but not for high-volume range sessions
