I just used a m15 to 1/2-28 thread adapter, and then an Huxwrx muzzle brake, torqued it on and it has been good to go. Can always rockset it if worried about it loosening. I'm waiting on a M15 huxwrx device, but may just give up and rethread my HK G36k barrel to 1/2-28 with a flat shoulder.

Griffin armament makes M15 to 5/8-24 adapter that butts against the muzzle, Griffin Thread adapter
instead of the taper and lined up straight with my silencer on my G3 build. Probably works great on the G36, but didn't want to be stuck running my longer 762 can on it.

 

Standard G36K or C flash hiders (like the standard G36/G3 flash hider) won't accept a suppressor. The newer universal G36 flash hiders (both three prong and bird cage) will accept a NATO QD suppressor, but the only ones I know that are are sold in the US are the B&T Rotex V/X/RBS, and Knight's Armament suppressors used with M4s, M16s and M27s. I'd also say Griffin, but I've been told that their stuff is cheap knockoffs of what Knight's does.

 

Both muzzle devices I listed above are designed to work witht he B&T Rotex v/x

 

If you got a surefire can you can try your luck and see if you can find a g36 muzzle device from em. Was lucky to find a g36 warcomp around the time my conversion was finished. It doesn't use the notches/latch.

 

I don't think the muzzle devices you pictured need timed with shims or crush washers or anything like that. Not familiar with the Claw Gear flash hider, but the normal HK muzzle devices don't need timed and are just torqued down to the specs that HK states in the rifle's instruction manuals.

My SG2000 fits right in the two slots up front. I'm sure it was designed so that you can tighten this down by hand with it and be fine since soldiers, especialy KSK/KSM, need to be able to switch to the BFA.

 

1) The spring does not keep the device tight, it simply help keep it from backing off. If mounting a can, use rocket and torque to 30-35 ft-lbs. Always follow up with a bore rod to ensure baffle clearance.

2) Metric threaded muzzle devices are muzzle-bottoming, not shoulder bottoming. If the device is metric threaded but requires a barrel shoulder, the MFG designed it incorrectly and you will have some issues with it.

 

Thank you!

 

I would target 30 ft lbs. No less than 20 ft lbs. Too tight or too loose may impact the accuracy of the weapon.
