Any suggestions for an ETU for CYMA nylon gearbox to replace trigger trolley?
I like these, for the price good value.
Use the code GBNOBODY for free shipping 
Also found they have been around 7-9 days postage of late which is pretty good for international shipping.
Edit… that’s a good easy no frills cheaper option.
If you want some programming I go for the 1.7 optical.
