My magzine after about 15 shots does not put a pellet in the barrel when cocked. Remove the mag reinsert & it puts one in the barrel but none after that?? Any suggestions?
Spring underneath probably needs a bit more tension. It's pretty easy to do. Here is a video from orioniguanahunter. He explains how to install his impact mag cassette replacement. It will show you how to put more tension on the spring.
