RT Pro Stops Shooting

[kurama]

Recently, my friend bought a new RT Pro off of ebay, and as always with ebay, the thing is having problems from the second he got it. The mag has an X Valve, LX Bolt, and a ULT kit on it. I can't get the level 10 pdf file to work (adobe's pdf viewer doesnt work with my OS for some reason...), so I'm asking for your help. Anyways, the Mag shoots fine, but on occasion the bolt will stick back. Upon investigating, the sear is where it should be, despite what I first believed to be the problem. What do you suppose the problem is that is causing the bolt to stick backwards.

Thanks for your time and help :cool:

Hmm. the bolt sticks backwards as in it will not move forward when the trigger is pulled? Try giving the LX carrier/oring a nice lubing. I used to have the same problem with my old rt classic. Still haven't figured it out. Good luck to you though

Thanks. I did that, and it seems to have helped a ton. The problem still persists a little bit, but it is not nearly as bad as it used to be.
