"It dropped into a G&G CM16 Mod 0 just fine. Pretty basic part, I’m really not sure what could go wrong with it. Seems like a solid build and has a smooth polish too. I combined this with a Lonex piston head and cylinder head. Some of the best upgrades I have done.

"This is a great spring guide, just a heads up for M14 and P90 users.

The CYMA M14 actually uses a V.3 spring guide so this will not fit yours, so just go for the lonex V.3.

As for the P90, the shafts on the base are too thick (Not tall), and require too much force to fit correctly, so I recommend sanding down from the inside just a bit from one side and a bit more from the other, this way it will have one side that slides right in and another that gets stuck to make reassembly easier with the spring in.
Another option would be to get a V.2 spring guide for your P90 and it will fit without modification. It's been proven to work many times, only difference is shorter shafts but that's about it, you would see no actual difference.

"I bought this as an upgrade for my G&P Magpul MOE carbine. It does not fit with the G&P gearbox, however, you can always do a modification of it, whether you grind the gearbox or the spring guide a bit to fit it in... and so far so good. Very sturdy spring guide.
