G&P Complete M4 Metal Receiver & Gearbox Airsoft AEG ProKit (G&P USA) Front Wire / Black

3 Customer Reviews

"I bought this receiver in hopes of rebirthing my broken m4 viper from Walmart. What I did was attach it to the barrel and stock and it worked like a charm. Though, when I was opening it, I found that the grip was polymer, not metal. To answer a FAQ, no it does not come with a hop-up. I had to exchange air nozzles from my old m4 for my old hop-up to fit.

Pros:
High ROF
great looks
Fully customizable
Easily dissembled for us Air-smiths out there

Cons:
Polymer grip
No hop-up
Sometimes needs to be modified

"A friend of mine recommended this set, and I am very glad I followed his lead. The only modification to the gearbox being a new piston, with the G&P "rapid-fire" front-end kit I have a nice aeg that performs flawlessly. Thank you evike for making these available!
