Hi im having a problem here, I did exactly what you said, and well mines wanting to do somthing a little different.

Im asuming the FVA is the velocity adjuster, mine has been adjusted before so I didnt know how to go about so what I did was I went flush with the body and then tightened it in a tiny bit. Then I went and tightened the Responce bolt in all the way, Pull the trigger.. and it shoots 3 round burst, so I sit there for a moment and think, so I adjusted the velosity in a tiny bit more and pull the trigger, and it shoots full auto but theres no sweet spot its just at random...

so now matter what I do when I adjust the bolt on the responce out it only shoots semi.

im stuck, any help?

Thanks.
