Adjusting hopup on an M4RIS
 

Hi there.
I've just got an M4RIS, but no manual came with the deal.
While i'm almost exactly sure what hopup does, i've read most on the forums here, i can't seem to be able to find the hopup adjustment... ive scoured both this forum AND google... i havnt found anything really reliable... even a link would suffice.

Thanks.

Hope this help

Btw the hopup should be behind the shell ejection (bolt) cover

.
 

Thanks.
Got it all figured out now, couldnt for the life of me find anythign related... being a first timer, i wouldnt have known. Thanks.
