amateur Posted April 5, 2009 Report Share Posted April 5, 2009 How long have you owned the gun, and when did the problem start? Quote Link to comment Share on other sites More sharing options...
Steady Posted April 5, 2009 Report Share Posted April 5, 2009 (edited) This happens if a pellet falls under the bolt and jams in the slot that the cocking pin slides in. The .177 is worst for this problem. A check on the sear /trigger wouldn't go amiss and make sure the travel limiter screws are backed off.

A check on the sear /trigger wouldn't go amiss and make sure the travel limiter screws are backed off. That is very good advice and pellet jamming is a real pain with the .177 calibre. It can be prevented with a bit a airline tubing cut down it's length and placed under the pellet probe. The biggest problem, if you haven't had the gun long and hasn't had much use, is the lack of lubrication (Moly Grease is best) and the roughness of the internal finish. These guns really do benefit from a full strip down and internal polish. You will be amazed at the performance improvement of one of these guns with a bit of TLC. As has already been suggested, if you visit UK Chinese Airgun Forum you will find a section dedicated purely to these superb little guns and many, like myself, willing to give you advice on tuning to get the best from them (not on open forum though).
