I never would have thought a muzzle break could make that mutch difference - DELTAC Slingshot Muzzle Brake For Mosin Nagant Threading Kit Combo

Everything worked perfectly. I opened the die full up for the first cut and completely closed for the second and it worked great. then when I went to the range it was a huge difference. A few weeks ago I could not fire more than a box of Ammo without my shoulder getting sore. after installing the muzzle break I felt like I could shoot all day. the neighbors hate it though the shooter to my right was getting hit with so much blast from the break he moved target point to get away. shooter to my left had to much stuff set up to just move so he asked for a warning before I squeezed off a shot. I finished the day without any pain in my shoulder. Hope this helps other people make a decision. This is truely a great addition to a mosin, So glad I did it.
