Hello,

Recently I've purchased a G&P metal body:
G&P SPR Metal Body (A Type) for M4/M16 series [Code: GP181X]

My will is to have a GB with a quick spring changing system in it.

So I got a A.C.M. Quick Interchange Spring System spare gear box For Ver. II (Front).

The problem was that in any way that fitted in my G&P metal body.
But I know someone that uses it in a G&P MAGPUL style Gearbox.

So, thinking that the problem was the metal body, I tried it in my DBoys metal body... TOTAL FAIL. The gearbox stucked inside and I have to break the body to set the gearbox free...

All in all...

Does anyone has an idea on a Gearbox with quick spring changing system that fits G&P metal bodies, or i'll have to use a G&P gearbox?


Att.
