Battle Arms Development Thmpr Muzzle Device .30 Cal Black
The Battle Arms Development THMPR (Thumper) Muzzle Device in .30 Caliber Black is an aggressively engineered compensator built to keep your muzzle flat, your follow-up shots fast, and your felt recoil firmly under control on 7.62/.308 platforms.
- Dramatically reduces muzzle flip and felt recoil for faster target reacquisition
- Precision-machined from tough, corrosion-resistant 17-4 stainless steel
- Durable black nitrite finish for long-lasting protection and low-glare aesthetics
- Compatible with .30 caliber rifles chambered in 7.62x51 / .308 Win
- Standard 5/8x24 threaded muzzle attachment — fits most .308 barrels
- Lightweight at just 2.2 oz — minimal added weight without sacrificing performance
Who This Is For
The Battle Arms Development Thumper is purpose-built for precision rifle shooters, competitive marksmen, and serious .308 enthusiasts who demand maximum muzzle control without adding unnecessary bulk. Whether you're running a gas-gun on a 3-Gun stage or squeezing every edge out of a semi-auto precision rig, the Thumper delivers measurable reduction in muzzle movement so you can stay on target and get back on it faster. It's equally at home on an AR-10, DPMS-pattern rifle, or any .308 bolt-action with a 5/8x24 threaded muzzle.

Frequently Asked Questions
Does the Battle Arms Development Thumper work on both AR-10 and bolt-action .308 rifles?
Yes — as long as your barrel has a 5/8x24 threaded muzzle, the Thumper is compatible with virtually any .308 Win or 7.62x51 platform, including AR-10 style rifles, DPMS-pattern builds, and bolt-action rifles with a threaded muzzle. Always confirm your barrel's thread pitch before ordering.
Is a crush washer included, and what do I need to install this muzzle device?
A crush washer is not included with the Thumper. You'll need to purchase a compatible 5/8x24 crush washer or peel washer separately to ensure proper timing and a secure installation. A basic armorer's wrench and muzzle device wrench are recommended for installation.
How does the Thumper compare to a standard muzzle brake in terms of recoil reduction?
The Battle Arms Development Thumper is engineered to address both muzzle rise and felt recoil simultaneously, functioning as a hybrid compensator/brake. Its port geometry is optimized to redirect propellant gases upward and to the sides, keeping the muzzle remarkably flat during rapid fire — a noticeable upgrade over many standard brakes in terms of muzzle control and shooter comfort.
