Unlike most other gearbox shells on the market, the Retro Arms CZ gearbox shells are precision CNC machined out of a solid block of billet EN AW 7075 T651 aluminum giving them unmatched durability and resilience. Combined with reinforcement of key stress points and stainless steel connecting bolts, the gearbox shell has undergone extensive stress tests with M160 springs without any signs of wear.
Version 2 Retro Arms gearboxes feature a quick-change ball-bearing spring guide mechanism, allowing spring swaps in a matter of minutes without complete gearbox disassembly.

(Write a review) "We installed one of these for a customer, I agree with the first review, and I have to add, if somebody out there is planning to install a Gate Astor, plan to paint the inside of the box flat black. not a big deal, but its soo shiny inside that the single sided boards get all screwy with the light bouncing around. Really should use a Titan or similar, but our customer provided the parts. "I have this in my VFC mp5, no fitment issues.
We all know how great and strong these gearboxes are so here are some things to note that arenâ€™t as great.
- Was expecting it to come in a box, instead came in a clear plastic bag, kinda lame but didnâ€™t affect the durability on mine
- The holes for the bushings are too small, I tried FLT, Modify, and even Retro Arms but none fit, I had to open the holes up for any to fit
- The screw used to mount the trigger contacts/board isnâ€™t the same size as most gearboxes. Not a huge deal but why?
- The qc spring guide is nice, but the torx head on the back is wayyyy too big, retro arms even sell a screw-in knob for the guide. Again, why? Write a Review
