HK MR223 A3 Silencer

Anyone know if an Ase Utra SL7 Borelock goes on a HK MR223 A3 with M15x1 thread?

I know Ase Utra has muzzle devices that fit their BoreLock design in M15x1. But I'm more wondering if HK has some kind of special M15x1 that might be extra long or extra short render it incompatible with regular M15x1 threadwork.

1. Yes, you can use the ASE Utra M15x1 BL.

2. The "problem" is the groove (is this the correct term in English?) on the HK thread / barrel. So if you use the original ASE BL you will have a gap. Not a technical problem, the supressor will work fine, but it looks strange.

3. The solution is to use a Klärig Engineering Brake, designed for HK weapons.

Damn that is a very huge gap! :-(

So how does the alternative brake work? Is it effective?

The Klärig brake is great. I have the original ASE brake on a bolt action in .308 and the Klärig on the MR308 (first picture). The Klärig is the same or better. Also compared with other brakes like e.g. Surefire it works fine.
