You are sure that the trigger is for the L96?
If so I would look at the spring guide, as well as your feed finger. If that finger is chewed up it could be getting stuck on the feed ramp.
Will you get the problem with the mag in or out of the rifle? If you only get it when the mag is in, you may have a problem with the mag itself.
