Kwa mp7 a+ devil hop problem
23 February, 2013, 16:59
Basicly ive fitted the hop bucking but there is very little hop have i missed something? I made sure the bit the that pushes down on the bucking was located in the small dimple when fitting, do i need to change anything else?

Re: Kwa mp7 a+ devil hop problem
The hob nub ( a tiny round piece of rubber like wire insulator etc) is supposed to go in the little dimple the hop arm alone wont provide enough pressure,

In the pic you will see above the hop rubber (top line middle tube) there is a small silver ball (most likely a ball bearing) if so can be picked up from a hardware store for pence once you have the right size :D

Re: Kwa mp7 a+ devil hop problem
On second thoughts thats a spring isnt it? So im suposed to add a nub (be it a piece if wire insulation or a bit of bic pen) to the arm?

Re: Kwa mp7 a+ devil hop problem
I've had no end of trouble with my KSC A+ rubber in my G18C (identical rubber/hop system) - you cna get lots of ball bearings for cheap off ebay, easiest way to get a replacement - I can have a look tomorrow to see what size you need.

Re: Kwa mp7 a+ devil hop problem
Fixed it i hope, find out sunday, didnt go the bearing route,
All i did was place an aeg gbox shim under the hop wheel on top of the arm seems to work great but like i said will see sunday if it works enough if not ill put another shim in simples
It seemed like a good idea because you can adjust it as you please on the fly.
