Just put one in a gen 8!

What do you mean don’t have to change the plate? Is that more of a gen 9 thing? Same with the yellow one? Cheers

j9/j10 stock motor is 460 long.

Ended up getting the acr j10 chi hai for $25 to see what thats like and was finishing an order so chucked it in.
If not Ill go from there

Will a metal gen 9 spring guide work on with the 92 box? @Rattler I think I remember you mentioned I may have an issue with this bit .

I have a spare gen 9 box I can take parts I need for the trigger bit.
Am I going to need something else with the fire select or trigger a gen 9 box doesnt have? Or is an upgraded version etc

Just trying to order everything I need instead of finding out later and waiting for postage.


Yes that spring retainer will fit just make sure it has the thread in the back because it needs it to be held straight or it will tilt.
I used a v2 trigger.
The fire select should fit np as will any v2 type

Oh lordy its arrived


Got some other stuff for it today like motor ,cylinder and bushings.

The piston head I ordered wasnt available so this was sent. Any one used , seems ok but a bit chunky no?
And what brand is this??

if it only has 6 holes it will have vacuum. i only had success with that style with 8 holes. also where the oring sits will probably need deburring back of holes

Yeah without taking it out the packet ,the 6 holes look tiny . Not going to bother with it . Just going to get rid of it . Cheers

Trying to find the perfect balance of large holes and also room for the oring to move a bit as some are tight little grooves once a green orings in

@CaptainAwesomepants this one above.

About to order a Perun v2 mosfet as Im not keen on spending any more than that and titan and leviathin too much.
Pretty much my best option yeah?
