Quick Disconnect QD Muzzle Brake M84
$100.00
More Than Barrel Bling
Sure, the M84 looks sharp on the end of your rifle, and yes, it'll get noticed on Instagram. But on an airgun, a muzzle brake does real work. When your pellet or slug leaves the barrel, it's surrounded by a burst of turbulent, high-pressure air that can push it off its line in the first critical inches of flight. The M84 acts as an air stripper, venting that turbulent air away from the projectile so it exits clean and settles into a stable flight path sooner. Less disruption at the muzzle can mean tighter groups and higher levels of precision downrange.
Caliber-Specific Inserts That Move With You
The M84 comes with the M58 Air Stripper Insert Kit, letting you fit the brake with inserts matched to your caliber for the closest possible clearance around your projectile. Own more than one airgun? Swap in the right insert and move the M84 to your next rifle. One brake, multiple guns.
Quick Disconnect Convenience
The M84 attaches to any air rifle equipped with a DonnyFL Quick Disconnect Adapter, so mounting and removing it takes seconds. One 1/2x20 threaded barrel adapter is included, and additional adapters are sold separately so you can set up every rifle in your lineup.
Features:
Machined from 6061 T6 aluminum
Durable black anodized finish
Lightweight at just 2.9 oz
Includes M58 Air Stripper Insert Kit with caliber-specific inserts
Includes one 1/2x20 threaded Quick Disconnect Barrel Adapter (additional adapters sold separately)
DonnyFL Yokozuna Muzzle Brake
$45.00
Quiet Meets Precision
The Yokozuna is already known for taming your airgun's report. Now you can get even more out of it. Designed specifically to pair with the Yokozuna airgun moderator, this muzzle brake gives you two benefits in one setup: the sound reduction you rely on, plus the precision-enhancing air stripping effect of a dedicated muzzle brake.
Why Air Stripping Matters
A muzzle brake on an airgun is far more than a cool-looking accessory. As your pellet or slug exits the barrel, it's surrounded by turbulent, high-pressure air that can nudge it off course in those first critical inches. The Yokozuna Muzzle Brake strips that turbulent air away from the projectile, helping it leave the muzzle cleanly and settle into stable flight quickly. The result can be tighter groups and more consistent precision downrange, all while your moderator keeps things quiet.
Built for the Yokozuna
Like our popular M84, this brake is engineered with the same air stripping design philosophy, but it's purpose-built to integrate seamlessly with the Yokozuna moderator for a precise fit and clean, unified look on your rifle.
Features:
Designed specifically as an add-on to the Yokozuna airgun moderator
Combines sound report reduction with air stripping performance
Made from 6061 T6 aluminum
Black anodized finish
