G&G GR25 upgrade advice

28 posts in this topic

Not an official prowin. Seen the state of some of those and gone for that style but different make. Right. Anyone know if the a&k lower reciever accepts the g&g upper? Thanks. Thinking about getting one to save shaving the innerds out of the g&g for correct fit.

Okay will order a full upper and lower. Saves me chopping and means i can come up with something funky with the gr body. Right so had another play as the gr gearbox and setup was misfeeding. Turns out a priblem with the tappet plate so replaced with a spare i had. No misfeeding and now getting a consistent 369 to 372 fps. Happy with that variance. Must just mean the spring is crap. What spring would people recommend as a true m140 spring. Looking for a consistent 430 to 450 fps.
