Lantac dragon gemtech quick mount 5/8 x 24 muzzle break - LANTAC Dragon GenTech Quick Mount .308/7.62 Muzzle Brake

Several issues with this break.
1.) The matting shoulder on this is very narrow, when trying to time the break so it was in the correct position the shims would skirt out. Had to machine the Shoulder to give it a wider area to mate up with the rifle barrel.

2.) Attached my Gem Tech Quick Sand suppressor. First time I fired it I was hit with a considerable amount of Blowback coming from around the break, I checked the suppressor to verify it was on correctly, it was. This was not a good thing. I believe the gas was coming from where the Wrench Flats are located. There needs to be more of a continuous shoulder before going to the wrench flats. This was when I used it on a 6.5 x 284 Norma, haven't tried it on lower calibers. It could be from so much gas from the slots in the break coming back toward the barrel end.

Positive Note: When used by itself it reduces recoil considerably!

Will update when tried with other calibers using the suppressor.
