whats the diffrence between a stock gear box and a retro arms

a standard gearbox has many intolerances as well is made from cheaper weak metals which always fail eventually. Especially if you upgrade your aeg theres added stress from the increased cycles, cycle time, and over all increased abuse. They all crack eventually. A retro box will never crack and since it is not off spec, upgrading is super easy and makes the process 10 times easier. You do not have to radius the gearbox, nor dremmel out stupid trigger contact threads to seat a mosfet. It is the best upgrade for any aeg. It is a shame to spend $500 on parts for your gearbox shell to break and potentially break other internal parts to just have to re build it. With retro, you build it once and forget about it with confidence.
