Before. After. I had Steve at ADCO install the TRX rail (13 incher) and the pig. I love the way it looks. The noise and blast is less but I do have recoil again and muzzle jump but the trade off is worth it in a patrol rifle. The gun is also lighter with the TRX rail. I am never going to use a normal heavy quad rail system again. Pat Wanna kill these ads? We can help!
