9mm 1/2x28 TPI Short Compact Mini Tanker Style Muzzle Brake / Linear Compensator 
 
This unique muzzle device combines the recoil reducing effectiveness of a muzzle brake with the sound and blast forwarding capability of a linear compensator. 
 
 Porting on the sides and top reduce felt recoil, and reduce muzzle rise.  6 ports on the front divert blast and sound forward downrange, minimizing the blast and sound generated by the side ports.  
 
High Quality aluminum construction reduces weight at the end of your barrel.
