Another excellent body from G&P. This product is lightweight and well made, with a good finish and well detailed trademarks. I've installed a CA gearbox in it without any problems.
This body uses the sliding forward body pin for removal of the upper receiver. Slide out the front pin, then slide the top off the bottom.
Most bodies do not require the trigger pin to be installed. Not so for this body, the trigger pin is crucial for correctly stabilizing the gearbox inside. It is roomy enough in there for the gearbox to be installed crookedly, so if you do not install the trigger pin, you may well end up with a gearbox sitting slightly forward and require you to remove the gearbox and seat it properly again.
All in all, a good product that I'm happy with.
Better quality metal than lots of other bodies out there
Another example of fine G&P manufacturing
The trades are as far from realistic as you can get. If you're looking for a seriously realistic metal body, this is not the kit for you.
G&P upper receiver threads are sometimes incompatible with delta rings from companies such as Madbull. ASGI sells a tool that can correct these threads.
I've installed KWA delta rings, CA delta rings and G&G delta rings without a problem.
