Awesome brace! - SB Tactical SB5 Pistol Stabilizing Brace for HK MP5, HK53, and MP5K RS Clones

Awesome brace, and no fitting was required with my z-5rs. Extremely tight fit!! At first I was worried that it would not fit, but as long as the receiver is to spec, should fit like a glove! It’s a little heavy, being mainly rubber/plastic, but balances well. If you have an mp5 pistol clone, this brace is a must!!! While it does not fold or collapse, this keeps it rock solid in place!
