Well, I'm bummed. I had hopes that everything would work out hiding my adapter and suppressor shoulder under the rail, but it's not working out.

I've checked tightness of the suppressor after each shot, and after the first or second shot, the adapter falls over to the nearest click, loosening up justa bit. This is because I can not manually turn the locking ring back over one click tighter when installing the suppressor.

Looks like I'll by swapping out for a shorter rail so I can get to the darn thing

I knew it may not work, and I've got designs in my head that would fix the problem, but the lack of machining equipment and the such dictate a shorter rail.



It's a 9" Core 15 barrel, 300 BLK. Specter length YHM Diamond series rail, YHM 7.62 SS

Have you tried using a strap wrench to tighten the suppressor down?   They're cheap and should work great,  they don't scratch or rub the finish either.

Im building a 9.5" Core15 pistol,  which gas block and buffer did you use?  Any issues with it?

The strap wrench wouldn't help, as the suppressor is completely seated on the shoulder. The problem is the travel of the locking ring that holds the suppressor in place as the QD feature and keeps it from loosening. I need to e able to click the ring into he next slot on the suppressor and can't get to it.

I used a Del-Ton .750 gas block, and wil probably step up to an adjustable gas block, as is recommended by Core 15, because it does not always cycle with Supersonic rounds unsuppressed. It cycles everything suppressed, but supers don't cycle unsuppressed, and I haven't wasted any subsonics unsuppressed so I don't know what they'll do.
