Never thought I would be posting in the tippmann section again Kinda like old people, I've come full circle. Started with a 98c 10 years ago, went through dozens of tournament guns, now I'm semi-retired and back to just my 'ol faithful. Right now the CVX valve is shot but that's alright because I wanted to LP it anyway. I've been looking around and it seems the LPK is still about 120 dollars on ANSGear and Action Village. Are there any proprietary Tippmann based sites that might have it cheaper?

Thanks but it doesn't look like they carry the LPK or many of its parts.

good luck on finding a LPK for any TIPPMANN any more.. they stop makeing them for a reason.. and the reason is they dont work.. Tippmanns Operating PSI is 800 psi .u can make it go as low as 450psi. but if u are useing a cyclone feeder it wont work at that low psi. MIN psi for the cyclone to work correctly is 600psi. OK well u can make it work ,But u will doing alot of tuneing to get it working correctly tho..

Sounds like it works fine to me. I don't plan on using a cyclone feed, just want to get the best performance on HP air and make a semi-tournament style tippmann so I can play scenarios or speedball with it.

Also they aren't hard to find at all, ANS and AV both have them. I was just wondering if there was anywhere cheaper.

Your best bet is pbnation bst, model98.net, or mcarterbrown.com for a used kit. Right now there is a dm ebolted 98 with a lpk but the whole package is 450. I actually bought a kit from ansgear as I couldn't find another site that sold them NIB.

I agree with this. I am really surprised that ANY store still has them for sale. They have been out of production for 3? years now.

Theres a guy over on Milsim Empire with a 98 LPK, only wants $65 + shipping.

Unless you find some sort of deal online, I doubt you will find them online for anything below $100. When I got the LPK for my A-5, I had to bite the bullet and pay the $110 it was listed for.

The LPK does work. My A-5 runs @ 350/400 psi without any issues whatsoever.

Contrary to popular belief, my Cyclone DOES work with my LPK although I had to cut a few coils off to allow the lower pressure to cycle the system because I have the QEPH installed as well as all of the other TechT Cyclone parts.
---> Cutting off the coils DID allow my Cyclone to operate with the LPK, but my overall BPS did suffer. I can still fire @ 15 if I wanted to, but I doubt I will be able to get it up to 26 BPS like I used to (haven't tried it).

You can pretty much piece it together yourself with parts that are still in production. I won't say that my a5 is low pressure because I haven't added a regulator. I'm probably running around 500-600 psi vs. 800 psi stock, so I'll say it's lower pressure. All it took to get a 200-300 psi drop was the Techt hammer and valve spring and a lighter weight hammer spring. If you want to add a regulator and try to drop it below 500 you may get away with needing just a heaver hammer spring to open the valve longer but you may also need a high flow valve.

I'm guessing the reason low pressure didn't take off on Tippmanns is that the internals are design for high pressure. When you convert to low pressure you are trading pressure for volume to propel the paint, but you still need a certain amount of pressure to cycle the internals. Tippmann internals are much heavier than guns designed for low pressure, so the cycle rate will drop off or the gun will not cycle at all if the pressure is lowered too much. Also the power tube is designed to propel paint at around 300 fps at 800 psi; drop the pressure too much and it will become impossible to get that without a narrower power tube and bolt assembly.

This thread's a tad old now but figured I'd update. Found an LPK for 50 bucks on here and it works perfectly. Had my 98c shooting around 240 fps with a regulator off of an original etek. I need to get a reg that'll output a higher pressure so I can get playable velocity but I'm pretty happy that all is working. Any suggestions for mid-pressure HPRs besides the stabilizer?

Is the front velocity screw backed out all the way? Is so you could look into a rear velocity adjuster.

This.

Having your FVA screwed in and your HPR adjusted to maximum output won't do you any good. Make sure your FVA is backed out enough to not interfere with the outgoing air.

No offense guys but I have owned a 98 for 10 years I have the power tube wide open. The LPK is a rear cocking system and doesn't allow for an RVA.

My conclusion is that it's my barrel. I have a 32 Degrees Nyte Stikk and it's not tapered at the breech to allow the bolt and hammer to fully move forward. With a regular HP setup, the drive spring was strong enough to work through that issue but with this lighter drive spring and lower operating pressure, the valve can't open enough to raise the velocity.

The approximate output range of the regulator I was using was 170-550psi and my fps difference was only about 50-60 at best when going from lowest out pressure to highest. I'm gonna grab a new barrel with a tapered breach and see what happens.

[ChesterMolester]

No offense taken.

Do you have the stock barrel laying around? God know that it's big enough to allow the bolt and hammer to cycle completely. lol

I do have the stock barrel but I used it this summer to knock the head set out of a bike frame for a build I was doing. In short it's mauled at both ends and will never be useable for paintball again. I don't need this gun working for another month or so when I'm playing a scenario so I've got a little time to get things together.

No idea why 32 Degrees decided not to taper the bore on those barrels, they did on every other one I've seen. Maybe trying to quiet the gun down and improve efficiency.

[ChesterMolester]

I've never seen that issue come up. Good to know for future reference.

LOL at using the barrel in the way you did. lol
