I bought my first Automag (Tac-One) a few weeks back from a guy on MCB. When I got it I aired it up with my GA Myth 62/3000 tank and it shot just fine, but it did not RT at all. I took it over to a friend's house (Ochsy here on AO) and we shot it some more, with his Ninja 1200psi reg and my Nitroduck 1000psi reg. Still wasn't very responsive at all, and by the time we stopped I noticed a very faint leak down the barrel. I sold my Tippmann A5 RT to get this, and I had really hoped for a RT effect. Of course, it's got an X-valve and a Level 10 bolt.
So, I ordered a parts kit from AGD, snagged a duckbill ASA with gauge, replaced the macro fitting with a new Ninja 90* swivel and got some new macroline from macrolineguy.com. I also picked up some white lithium grease and some Tri-Flow oil. I completely broke down the X-valve and checked all the o-rings. The powertube o-ring was a dark tan color (I remembered the very faint leak down the barrel) and the reg piston o-ring was brown. I replaced both of those, cleaned everything else, re-greased the spring coils, oiled it all up and put it back into the Tac with the silver (longest) bolt spring. It originally came with the gold spring in, but I wanted this thing to be as gentle on paint as possible. Because I had changed the powertube o-ring, I checked the carriers again. I only have four - plain, one dot, one ring, one ring & dot. Apparently there's a carrier with two rings, which is the largest, but I didn't get it. I installed the largest carrier as it seemed to move easily on the bolt. (It originally came to me with the "one dot" carrier in it). I also put in two shims because that's what the level 10 quick start video said to do.
Then I aired up. Surprisingly, my GA Myth reg was putting out about 850 to 900 psi based upon the ASA gauge. I pulled the trigger, and .. nothing. If I turned up the velocity, the trigger pin would reset (but not fire). I pulled again.. nothing. Same thing, turned up the velocity more, and the trigger pin would reset. This continued until my valve started venting out the back. I turned the velocity adjuster back to the line. More searching on AO led me to realize I was getting bolt stick. I was using the largest carrier I had, so I didn't think that was the problem. It had to be the spring. So I switched to the red spring. The same thing kept happening, but every once in awhile I could get the gun to fire. Mostly, though, it was a lot of bolt stick. So before giving it up for the evening, I swapped back to the gold spring. The gun fired just fine then, but I started noticing a leak down the barrel. The Tom Kaye troubleshooting video said to fire and hold the trigger. My leak stopped. My guess is that I had too large of a carrier installed.
So I came back to the gun today and swapped out the carrier to the next size smaller. I also took out the shims. I aired it up and the gun fires just fine - one shot at a time. The level 10 bolt works well too (tested it with a squeegee and then my pinky finger). It just still will not RT. My Nitroduck reg is putting out 1000 psi and it will not RT.
Does anyone have any ideas where I should start next with this thing to make it more responsive? The one thing I think about now is that I haven't chrono'd it (might be able to do that tomorrow). If it's shooting at a low velocity, will turning up the velocity make it more responsive?
