Follow up on intial review

Since the main point of this product is the muzzle brake I refrained from giving it one star but the wrench is garbage. Muzzle brake works great but the wrench that comes with it is crap. I snapped mine trying to tighten down the Sherman Muzzle brake and ended up using a screwdriver wrapped in padding to finish the job

Does itzs job well

Not only does it look bad ass it tames the rather nasty recoil of the KSG especially when firing 3" shells. Despite its size and weight did not seem to make the weapon too nose heavy either. Great product and works exactly as advertised.

Works on Ks7 with mods

I modified it for use on my KS7. Needed to file on it to allow the magazine cap to fit and to time it but after that looks great. Steel is much better than the aluminum version from other company.

Muzzle brake

I shot 3 inch magnum buckshot and felt it. I installed this muzzle and tried it again. I could tell a huge difference this made. Cut the recoil over half. The wrench it came with was very thin an I actually broke it during the install. Great product.....



I installed this muzzle brake on my KSG and was amazed at how much it reduced the recoil. Combining this with the installation of a reduced recoil butt pad made the shotgun a pleasure to shoot. No problem blasting away using 2 3/4" slugs in just a T shirt. Felt recoil was minimal.

Installation was easy. I used a different method then the one shown on the installation video. Wasn't a big fan of the spanner wrench that came with the muzzle break so I went a different route and the installation came out just fine. Definitely order the Rocksett when you order the muzzle brake.
