if the micro rock works then the good news is that you set the the frame up correct and that your LPR either needs a good cleaning, maybe a different spring, a new seal, or worst case scenario a new LPR...but the Micro can fit in your frame so its all good!!!
Nope. You forget the M90 was milled specifically for more room. I would have to tear the entire thing apart, hog out the bottom of the frame a essentially start from scratch to even maybe get the Rock to work.
i would recommend taking the LPR out of your other frame to test on this frame, but you probably dont want to take the LPR out of your other frame? just throwing options out there for ya big Dawg so you can get your Mag shooting the way you want it to! one way or another you are gonna have to swap LPRs so you can see if you set everything up properly as well as to see if you have a faulty LPR?
you can also shim the LPR or use a stiffer valve spring or both?
Too much work. I'll use the rock to test but its not an option for actual use right now.
I guess I'm not grasping why the LPR would be bad? It is regulating the pressure. If I turn it down there isn't enough pressure to push the ram. I open it slowly until it is letting enough pressure through to allow the ram to trip the sear. It just seems as if the pressure needed to trip the sear is high. What am I missing?
dont really know if your LPR is bad either, but its possible? some ticklers work for a pneumag set up while others don't...being hit or miss is a very true statement
just swap the LPR in this frame with the LPR in the frame you say works and see what happens or buy/make a LPR pressure tester? i have a extra Reg tester i could sell ya...you just need your own gauge, and i have a extra CCM LPR as well
if you have another tank you can zero the lpr in the frame and mount the other one to an asa and run the lp hose to it just to test it.
Finally got air and did some tinkering again. I am seriously thinking that the MPA 3 is part of the problem. There is a C clip that holds it together and I think I bent it when I was trying to take it apart once. The C clip seems to be kind of rubbing the ram as it comes out. When I was dry firing it with the grips off it would do fine slow, but when I tried going faster I would see the ram get stuck slightly in the out position causing it to chuff. Of course now I am out of air again. :mad:
Heres a little trick to try: increase the gap between the ram and the sear. It mechanically increases the dwell to the valve allowing a couple extra ms's for recharge. 1/8" is a good place to start.
I didn't. Ran through both of my tanks again after grinding down the bolt head and realizing the ram was sticking. I also sent the Micro Rock off to someone for measurements so it will be awhile until it's back :ninja:
Sooo. After getting a new MPA, still having issues. Decided to switch back to the spring lever since it worked, just not super walkable. Got it back together last night and used up the rest of my air, every thing worked well, good enough. This afternoon, I run out to get air, take the valve off to polish it up all pretty since I planned on trying to use this this weekend. Put it back together and nope! In order to get it to fire I am having to turn the lpr up so much that its leaking.. IT JUST WORKED LAST NIGHT!. Finally I pull the MSV out and try it by hand same results. Starting to think maybe the LPR is the culprit, yes I am that stubborn. Take the top off and see some crud in there. Clean it out, pull the piston and spring out, clean every thing up and put it back together. Takes me 10 minutes to get the LPR back into the frame and still no joy. Really starting to get irked now. I finaly take the cap back off, pull the piston back out and look at the o-ring. Start to check it for dirt and it crumbles in my hands... Hmm. This might be a problem.
FTR, the large on/off O-ring that fits on the top of the on/off seems to be the correct size. Aired it up and ran half a tank of air with no issues besides having to fine tune the trigger stop and adjustment on the MSV so it isnt to far forward or back and so far, so good. Might actually get adventurous tomorrow and throw the magnet modded MSV back in to see if it will work now.
BTW, yeah you were right Reebs, the LPR was the culprit. Dood ;)
