Help Wirh Promaster

[Caddy24Roy]

I cleaned all my gear after my last game in November and I took all my gear out and checked it and aired up my promaster only to hear a leak coming from the front of the LPR. What is going on its only been used 2 times last year. Need sum help here ive got no idea what to do. Also I want to get a new barrel. Does the autococker have the same threads??

yep, the promaster uses autococker threads. any autococker threaded barrel will fit it.

The leak is due to your LPR piston o-ring. This seems to happen sometimes if you dont use the gun for awhile and dont lube it before airing it up again. It happened to my freestyle when I aired it up after leaving it in the closet for 5 months. You need to take apart the LPR and lube the piston o-ring, reassemble, and see if it still leaks. If it does, you need to replace that o-ring altogether. here (http://totalgreif.com/video/LPRlube.wmv) is a video of how to take apart your LPR.

the size of the LPR piston o-ring is 015. You should be able to find it at a local hardware store, I know Ace hardware generally has a good selection on individual o-rings and they only cost a few cents. If you cant find an individual one, I would recommend buying an o-ring replacement kit from www.markerkits.com, that way you'll have all the o-rings you need should any o-ring in your gun go bad. You can also buy LPR rebuild kits from www.icdunderground.net but since you only need that one o-ring, I'd recommend a full o-ring kit from markerkits since they actually cost around the same amount as an LPR rebuild kit, and you'll probably get more use out of the full o-ring kit.
