I wasn't able to test it out, I've just installed the new mechbox in the gun, and I fell in love with my spare M4 I had, as it runs like a beast. M16 is now my backup and for sale, but the only thing I see that could cause compression issues is the nozzle not sitting fast enought into the hop-up. This might be fixed with a good nozzle which slides free but still seals, and a strong tappet plate spring to make sure it gets back fast enought.
