## Description

The Windham Weaponry .450 Thumper is a semi-automatic rifle chambered in .450 Bushmaster, a caliber built around putting large, heavy projectiles on target with authority. At 7.2 lbs. and a 16-inch barrel, it's compact enough for hunting in dense terrain while still delivering the terminal performance the .450 Bushmaster is known for. Windham Weaponry manufactures in the U.S.A. with a team of experienced builders who came out of the original Bushmaster factory.

### Detailed Features
The gas impingement system cycles smoothly and keeps recoil manageable given the caliber. The upper and lower receivers are forged from 7075 T6 aircraft aluminum, high strength-to-weight ratio that keeps the rifle from getting unwieldy. The black hardcoat anodized finish resists corrosion and wears well in field conditions. The Luth-AR buttstock is adjustable, letting shooters set the length of pull to fit properly.

## What Customers Say

*AI-generated insights from customer reviews*

The Windham .450 Thumper gets a generally positive reception, with most discussion focused on the .450 Bushmaster caliber's performance and the rifle's build quality.

Stopping power is the lead topic. Hunters who pursue larger game appreciate the .450 Bushmaster's effectiveness, and the semi-auto action makes follow-up shots faster than with a bolt gun. Most users are satisfied with the anodized finish and the overall construction, and Windham's QC gets good marks. Accuracy is rated well when the rifle is properly zeroed and fed quality ammunition. AR-platform compatibility means the Thumper accepts a wide range of aftermarket stocks, grips, and optics, which users find appealing.

Recoil is more noticeable than with smaller-bore ARs, and a few shooters mention it affects their split times on rapid follow-ups. Weight gets mixed reactions. Some appreciate the solidity, others find 7.2 lbs. tiring during long carries. Pricing draws some comparison to competitors in the segment, though most feel it's reasonable given Windham's manufacturing standards. Reliability is broadly positive, though a handful of users note that ammunition choice matters. Some loads cycle more cleanly than others.
