whats up people, this is my first posting on pbnation so hopefully i get it right.
anyways i have a mq2ed karni that is giving me all kinds of grief. this is my first mq2 and is fixing to be my last if i cant figure this out. the rundown on the problem is (well the biggest issue is my velocity) i cant get it to shoot over 250 fps i also have blowback issues which i have been able to bring under moderate control with the bolt closed delay i also infrequently have shootdown issues. i've spent the last few weeks searching the web and trying to trouble shoot it. one thing i've tried with no luck was the allen head bolt on the front of the popit its in there tight as can be and now the bolt sticks open from time to time usually if i shoot a ball but not on dry fire so i'm pretty sure the bolt is too tight. i lubed all the parts with dow 33 and put on fresh orings.
sear is set to 4 mil secs. even tried a e1 board with higher sear on settings. i'm completely at a loss.
things is its in a halfblocked karni and only the top tube has been milled so even if i wanted to just put in a regular valve i would have to mill the bottom tube for the bolt pin to connect with the hammer i'd like to get the mq working but am just sick of messing with it i want the gun to be reliable. any thoughts would greatly be appreciated.
i'd also like info on getting the milling on the lower tube done should i decide to go with a regular valve specifically who can i get to do it for me
the set up is as follows
e2 zero b 1.10
stock karnivor front pnuematics
cp reg (i've tried it all the way up to 300 psi which any higher the gun leaks)
don't think any of the other parts are relevant to the mq working but they are as follows
i've tried two bolts
2k6 black magic stock, and an unknown delrin bolt that came with the marker
and of course i'm using a barrel kit with correct sizing
tried freak, death stix, and evil pipes.
any other info you need just ask
