5KU SAS Front Kit for Elite Force / UMAREX GLOCK, ISSC M22, SAI BLU, Lonewolf, & Compatible Airsoft Gas Blowback Pistols

"The mounting screw wouldn't line up on my strike industries ark frame, after attempting to modify it my whole bottom picatinny rail piece broke in half, so after slight modification I now attach the top piece to my stainless steel guide rod using a longer screw, it's a little more effort mounting it, but once on nice and tight it works even better this way then it did using the picatinny rail, also I had to dremel out and polish the inside of the threaded peice to expand the radius for a 9mm to be able to slide through smoothly as I planned on live firing my pistol with this attached. This was my work around for my state (Washington) banning threaded barrels, and after a little trial and error it worked out great, I give this product a solid 8/10. I think this is actually better then having a threaded barrel cuz of the ability to remove it anytime, and any suppressor, compensator, muzzle break I've tried works great on this so yea it holds up on even a real steel platform

"Perfect for mounting any sized suppressor on a glock without stressing the outer barrel. Only think I'd say is that with the heavy tracer unit I have he plastic lower frame on my we g18c sags down ever so slightly but it doesn't really affect much.

"Great product! careful with the threading there is a chance it can strip if you are too vigorous with overtightening it.

This also fits on a TM Hicapa 4.3 - to make it work I added some small paper spacers at the base to raise the front kit to meet the Hicapa barrel height. Works like a charm!
