DETAILS
- description
Electric blowback gearboxes carry extra hardware inside the shell, and the piston is profiled around it. A conventional piston will not clear.
This is the blowback profile with fourteen teeth on a steel rack. Tooth count and head fitment are entirely ordinary; it is the shape of the body that differs.
Blowback designs vary between manufacturers, so compare this against the part you are replacing rather than ordering on gearbox version alone.

Good to know before you buy
We list this as the blowback pattern because that is how it reaches us. If your blowback unit is an aftermarket conversion, check the profile against your existing piston first.
Frequently asked questions
What makes a blowback piston different?
The body is shaped to clear the blowback mechanism inside the shell. Everything else about it is conventional.
Will it work in a gearbox without blowback?
Mechanically it may well, but there is no reason to choose it. An ordinary piston is the simpler part for an ordinary shell.
Is the rack full width or half?
Full width, across fourteen teeth.
