| Cannot shoot over 250 I am having trouble with my A-5 with a Dead On power tube. Dialed all the way in and brought all the way out, I cannot get my gun to shoot more than 250 fps. I have adjusted springs, replaced springs, nothing. What could the problem be  |

| Re: Cannot shoot over 250 What air source are you using? What is your total setup? IF using a regulator, what pressure is it reading? Have you replaced the drive spring?

| Re: Cannot shoot over 250 Welcome to A5OG! Did the problems start when you installed the new powertube? Did it do this before? Are you using HPA or CO2? I had the same issue with my A5. It can be the older style rear bolt and valve. I called Tippmann and they replaced mine with the new style X7 rear bolt and valve. It has to do with the way the valve is made. There is some different milling to the new valve. If I used CO2, I was OK but when I used HPA, I had the low velocity issue.

| Re: Cannot shoot over 250 Most likely will be the valve. This is the old style valve  This is the new style x-7 valve  Call them and see if they send you a new one or purchase it from tippmannparts.com |

| Re: Cannot shoot over 250 Well, it's still a little cold in some places. If that applies to you then cold CO2 loses a lot of pressure. And just for some clarification, how exactly did you replace the drive spring? Did you just go for a straight stock spring swap or did you use a spring kit? Also do you have a buttstock or other non-stock end plate? Sometimes those have a deeper spring hole and you lose some tension from it.

| Re: Cannot shoot over 250 Receivers could be torqued down to by the bolts. turn the bolts by like 10 degrees counter-clockwise. How cold is it where you are playing? As asked before, did the issue only arise after the install of the powertube?

| Re: Cannot shoot over 250 It's possible the stock has a spring hole that's too deep. Try placing a BB in it to take up some slack of the drive spring.
