Tippmann A5 with E-grip, flatline, CP reg, double trigger, dead-on drop forward
Easy to install, works - alright.
Rear bolt (hammer) o-ring groove was sized incorrectly.
Inconsistent and low velocity.
I bought this set up so that I could run compressed air instead of CO2 (it makes a big difference in Houston's heat and humidity). I installed a CP regulator instead of a Tippmann because it was readily available and Tippmann's wasn't - they should have included one in the kit. I've had two problems with the system
1. With a stock velocity spring I couldn't get the velocity over about 285. Not bad considering that I'm using a flatline but just to get the velocity that high I had to turn the velocity screw almost all the way out. I lost the first screw the first time I used the system and the second one my second time out. I managed to hold onto the third one because during a game it cross-threaded itself into my aluminum (not stock) valve assembly. I had to force it out and cut a new thread to get it back in. I have since bought a spring kit to force the velocity back up - more on that below.
2. The gun was also relatively inconsistent. At first I just figured that's the way Milsims are - no biggee - but I checked out Tippmann's support section on their web-site and they recommended checking the rear bolt o-ring. Sure enough, it was loose enough to spin in the groove (the only one on the gun anywhere near that loose - imagine the o-ring on a CO2 bottle after you unscrew wrong and vent the entire bottle). I had some spares so I replaced it only to discover that all of my o-rings were loose in the groove. The groove wasn't sized properly. I sent an email to Tippmann support explaining what I'd found and asking what I should do. They told me to send the gun in with a copy of the email and they'd fix it under warranty.
I sent the gun in. They sent it back and the only repair I've noticed is a replaced board (the day before I sent the gun in, it started going full auto in the response mode and the only way to keep it from firing was to hold the trigger). I;m glad they replaced the board but it definitely has the original (low pressure) rear bolt with the improper o-ring groove and it is still inconsistent (+-20 fps - to get the top end up to 285 I can expect the bottom to be around 240 sometimes).
I'm not finished with Tippmann yet. The marker is still under warranty so I'll get back with them after the holidays and I'll edit this if necessary.
This would be a great product if the rear o-ring fit. I'm still seeking resolution on this issue and I'll edit my review if Tippmann steps up - or if I find a replacement rear bolt that works well. My problem may be a one time only deal.

The low pressure kit instructions (from Tippmann) say to set the input pressure to 325 psi (I just checked them) so I don't think that's the problem. However, I currently have mine adjusted to 450 just to get the velocity up without having to screw the velocity screw all the way out. I forgot to mention that in my review. By HPA are you referring to high pressure air as opposed to CO2? If so, I;m running that. That's why I bought the LP kit.
