A-5 e-grip HELP!! + LPK

I have an a-5 with an e-grip that was having issues with the pin, sear, and bolt about a year ago. Tippmann said they had a fix and sent me a new bolt, sear, and pin. well....i stopped playing shortly after that, until about a month ago. Last weekend my gun started acting like the bolt and/or sear is shot again (uncontrollable full auto when pulling the trigger, double firing.......etc.) Well, I decided to go ahead and get the LPK for the gun since I heard it comes with a new hardened bolt and I wanted the other benefits of the kit. Well, I ordered everything and then read on here people are still having problems with the LPK + e-grip.....and more specifically with the e-grip period. Is their any new info on this? Is tippmann aware of this problem? They won't send out a bolt for the LPK since it is a kit, which means I'd have to send my gun to tippmann every 3000 rounds or so. There has got to be some info on a fix for this? On a related subject, I bought the LPK + lapco universal adapter + Palmer stabilizer + spoon 8 inch drop forward. Has anyone tried this setup, and did you have to modify some lines to get these parts to fit together? Also, am I correct in understanding that with the palmer, I can still use c02 with the LPK without damaging anything?

NO, your board received oil drainage from the rear bolt. Thats what needs to be replaced- the e-grip board is a bit exposed, and you should either store it lying flat on the side without the cyclone, or dry it out of oil. What happens is in between use, you're sitting it (or moving it around) in a position where the oil in the rear bolt will slowly drip down onto the board. I use a gun case and keep it flat when I'm storing it. If I have to stand it up, I store the gun upside down.

how bout a new drive spring? give that a try

I don't see how a drive spring will stop wear on it- mayhaps you should look into the sear spring- this may be warped or damaged and causing the sear not to catch fast enough and wear abnormally on the bolt and sear. Try ordering a new long trigger spring and see how that does you.

Yeah....at least I think. The lip on the bolt is kind of rounded, I'm assuming it's supposed to be more edgy. I called Tippmann and they are sending me a new sear since the LPK doesn't come with one. I guess I'll just have to put everything together and since if this happens yet again. Is it possible to over-oil a gun and make the bolt and sear too slippery? While I'm at it, does anyone know if you can run c02 on the a-5 with a low pressure kit installed. My kit is on the way, but I haven't decided which tank to get yet, so I'd like to play with the gun on c02 for a while.

LordJovian wrote: Yes, you can. The only problem is that you'll need a Palmer Stabilizer instead of a normal regulator to drop the pressure input into the gun. CO2 will rust the springs of a normal reg and screw it up. Plus you'll have to order the low pressure kit (spring) for the stabilizer. Or use an old crappy reg for temporary use. Over-oiling the rear bolt shouldn't cause this, it should prevent it. However, the bolt will still wear with oil and the oil will pick up small metal shavings (dust) and if the oil isn't cleaned out and replaced, this can cause abnormal wear. You may also want to polish the internals, as this causes less foreign particles (paint overspray) to pollute the oil, and will smooth operation and allow you to drop the pressure a bit more. Don't over do the polishing, just get the overspray off (it doesn't need to look like a mirror).

Okay.....I ordered a male plamer reg for use with my LPK. I don't see anything about a new low pressure spring for the palmer though......can you point me in the right direction. And thanks for the tips, i'm gonna read up on polishing the internals.

I read that.....unfortunately I allready ordered the regular one. It's from countypaintball.com so I'm gonna see if I can send it back and get the other one. If not, this one will still work for what I need, right?
