Featuring nine precision-machined ports, the 9-Port Mega Thumper aggressively redirects propellant gases laterally and upward for maximum recoil reduction and near-total elimination of muzzle climb.
Stay on target and deliver faster, more accurate follow-up shots—even during rapid or sustained fire.
This oversized, multi-caliber beast is perfect for pistol caliber carbines (PCCs), AR-9 builds, rimfire rifles, AR-15 platforms, as well as straight-wall cartridges upto .350 legend.
It safely supports a wide range of popular calibers from .350 Legend down to .22LR, including .223/5.56 NATO, 5.7×28mm, 9mm, and everything in between (bullet diameters up to ~0.40”).
The generous 0.43” (11mm) exit bore ensures ample clearance for all compatible projectiles, providing worry-free operation with zero risk of strikes.
Precision CNC-machined from aerospace-grade 6061-T6 aluminum for exceptional durability and a light weight 2.8 oz weight.
The rugged black hard-coat anodized finish delivers resistance to corrosion and wear—while giving your build a sleek, tactical matte look.
