G&P Reinforced V.2 Gearbox Set with 8mm Bearing for M4 MP5 M16 Series AEG Rifle
by Corey M. Date Added: March 22, 2009
I cant really say anything good about this gearbox. I never used it long enough to see how it holds up. It fits fine in my ics mp5 lower receiver but it wont fit in my classic army m15a4 lower receiver. Its a good deal considering what it comes with and the price but i would suggest going with a different gearbox spend the extra money. the bearings work very well but just wasn't worth my money
