Overall Customer Rating of 17 Reviews:


The shim washer was perfect and the muzzle brake looks better than the Hitech version!!!

Also with the tools that come with kit makes install a snap!!!

Must be working

The installation was not the easiest. 4 stars because of the Chinesium wrench that broke during the install. I had to use a pry bar wrapped in a rag to get it to index correctly. Other than the install, it must be working because I put a mix of low velocity OO buck, high velocity OO buck, and bird shot through it yesterday, probably 150 shells total. Today, there's no bruise on my shoulder so it must be working.



First impression: This thing is badass and couldn't wait to get it installed. Unfortunately the crush washer was missing but these guys had a new one there very quickly. After a slight hiccup with the wrench breaking, I got it on the shotgun and man does it look great. I am a huge fan of the mini shells and I finally had the opportunity to test out this thing on my KSG. There is definitely a decrease in recoil. Shooting the mini shells is like shooting a pistol caliber carbine. Even 2 3/4" slugs were manageable and I was disappointed I didn't bring more with.

Bottom line, BUY it. It not only looks badass but does help. I cant say if its a 70% reduction but there is a noticeable difference. If it wasn't for the broken wrench and missing crush washer I would have given it 5 stars.

Sherman Tank Muzzle device

Looks good on the KSG, the jury is out on the recoil reduction. Will update once I get to the range. Install is easy.


Well now that I have actually used it I just wanted to say WoW what a difference ! Tames those 3 inchers way down!
