"Used this to attach threads to a G&G mp5a3. Soft but clean threads.

"Fits cyma platinum MP5. reduces the gap of the that the 3 prong has. Doesn't completely eliminate gap but it's threaded pretty deeply so if you wanted flush, you could carefully Dremel it. Personally I'm fine with the 1/8 of an inch gap. Better than the inch there was before.
