Upon closer inspection, I didn't feel that the threads actually sufficiently obliterated the groove as I initially thought. So, I ended up using some "Higher Strength" JB WELD in the groove. The "Higher Strength" formulation provides slightly over 5000 psi of strength added in the groove. I figured that it would fill in the gap between the reduced barrel OD at the groove and the muzzle brake, filling up the void that would otherwise be caused by the barrel groove without any filler. Then, with the muzzle brake screwed tightly in place, I theorize that the muzzle brake would also add to the strength of the barrel at that point, since the body of the muzzle brake would be covering the JB WELD filled gap completely. I'm using a Tapco AK bird cage muzzle brake. It's made to resemble the AR15 bird cage, but the bore is for the AK round. It's beefier than most muzzle brakes, about 2 ounces, which is not typically desireable with respect to adding weight to the rifle, but in this case, I theorize that the benefit of the beefy muzzle brake will serve to add strength to the barrel at the groove.

The photo attachment entitled "groove 1" is the original groove in the barrel, after the threads had been installed, and the photo attachment entitled "groove 2," is of the groove filled with JB WELD High Strength epoxy.


Please comment on whether you believe JB Weld High Strength will be beneficial, a detriment, or of no additional benefit?
