Key Features
- Adjustable LBA Trigger – The Lightning Bolt Action trigger lets you dial in pull weight from 2 to 7 pounds, so you get a crisp break without overthinking it. Why it matters: a clean trigger pull means tighter groups when it counts.
- Spiral-Fluted Bolt – Reduces friction and adds a bit of style, making cycling smoother even in messy conditions. Why it matters: less drag means faster follow-ups and reliable feeding in rain or snow.
- Threaded and Fluted Barrel (20 in.) – The 1:24 twist barrel comes threaded 5/8-24 for muzzle brakes or suppressors, and fluting sheds weight without sacrificing rigidity. Why it matters: you can add a can to cut noise, and the fluting keeps the rifle light for all-day carries.
- Crossbolt Safety – A simple, positive safety right at the trigger guard that locks the sear. Why it matters: no fumbling or guessing—you know it’s safe or ready with a thumb push.
- Removable Box Magazine – Holds 4 rounds of .450 Bushmaster, letting you load up quick or swap ammo types in the field. Why it matters: faster reloads than internal mags, and you can keep one in your pocket for backup.
Who It’s For
This Patriot is built for the hunter who wants a straight-wall cartridge that hits hard inside 200 yards—think deer, hogs, or black bear in thick cover. It’s also a solid pick for the recreational shooter who wants a manageable big-bore without recoil that’ll rattle your teeth. First-time buyers will appreciate the simple controls and the adjustable trigger that grows with their skills.
Pros & Cons
- Pros: Affordable price point for a .450 Bushmaster rig, threaded barrel for suppressor use, adjustable trigger out of the box, lightweight synthetic stock won’t warp, and Weaver bases are included.
- Cons: The synthetic stock has a bit of flex under heavy sling tension—not a dealbreaker, but a minor trade-off at this price. Per Mossberg specs, the stock is designed for field durability, so it holds up fine for most hunting scenarios.
