Bought a brandy new LEO Benelli M4 with full working collapsible stock. Functions great, very reliable and a good shooter. Only one issue, when in position 2 (the mid position) the stock auto unlocks and collapses itself when rapid firing 4 - 6 shells. I'm not even talking high powered stuff, just light birdshot will do it. Putting it in the mid position and rapid firing 4 - 6 shells, the stock auto unlocks, and collapses while firing. By rapid firing I mean pulling the trigger close to as fast as you can.
I called Benelli customer service, they asked me to send the shotgun in. Did so, the tech said nothing was wrong with it. It turned out that he just fired 2 to three rounds normal speed (not rapidly) figured I had the stock in the "disassemble" notch (I didn't) and said it was fine. Called up to complain, they sent me a new stock, said maybe the old one was faulty. Put it on, tried it. Experiencing the same issue...
Has anyone else ever experienced or heard of this issue happening before? What can I do now at this point?
Thanks!
