Key Features
- Fluted 20″ Barrel — WHY IT MATTERS: Reduces weight by roughly 0.3 lbs while increasing surface area for faster cooling, so you can fire follow-up shots without losing zero.
- Threaded Muzzle (5/8×24) — WHY IT MATTERS: Lets you run a suppressor or muzzle brake instantly, cutting recoil by 30-40% and keeping your sight picture flat.
- Adjustable Trigger (2-7 lbs) — WHY IT MATTERS: You can dial in a crisp 2-pound break for precision shooting, which is rare at this price point and a huge advantage for tight groups.
- 10-Round Detachable Magazine — WHY IT MATTERS: Gives you the capacity to stay in the fight longer without reloading, critical for competition stages or multiple shots on game.
- Synthetic Stock with SoftTouch Coating — WHY IT MATTERS: Provides a secure grip in wet or cold conditions, and the stock won’t warp or swell like wood can.
Who It’s For
This rifle is for the shooter who wants .450 Bushmaster performance without dropping a grand. It’s ideal for competition shooters running heavy-hitting divisions, hunters after thick-skinned game at moderate ranges, and precision enthusiasts who appreciate a rifle that shoots sub-MOA with the right ammo. If you’re building a dedicated straight-wall cartridge rig for states with restrictions, this is your ticket.
Pros & Cons
- Pro: Sub-MOA accuracy out of the box, verified by multiple shooters on forums. The fluted barrel and adjustable trigger are genuine performance upgrades.
- Pro: Threaded muzzle makes suppressor mounting easy—no gunsmith needed.
- Con: The synthetic stock feels a bit hollow compared to higher-end chassis systems, which can affect balance for some shooters.
