stevenb Posted September 28, 2004 Share Posted September 28, 2004 Yesterday, I picked up my Benelli M4, model number 11703. I lubed it up and assembled it out of the box. I went shooting within a few hours of getting it home. I began shooting some 2 3/4 birdshot. Perhaps 40 rounds of it. I shot a few 2 3/4 buck shot loads and a few slugs as well. So a total of about 50 rounds or so. That last 20 rounds seemed to be firing slugishly. I inspected the chamber but witnessed nothing wrong. Then, a massive failure happened. Something was binding the bolt up from loading a fresh round. It looked like a small metal rod. It turned out to be part of the gas piston. I had to disassemble the weapon to clear the jam. Here is a picture of the shattered gas piston. Looks expensive doesn't it? I inspected how the gas system was installed, and consulted the manual and determined that it was assembled properly from the factory. The steel looks extremely brittle where it busted. Notice the rings around the smaller portion of the pin that broke off. So now I have to mail this piston to Benelli, and perhaps they might give me a new one after I just spent 1300+ dollars. I get to pay for some more shipping. The customer service wanted me to send the entire gun. I explained to him the possibility that it is a metal failure of the piston only, since the other piston looks fine and it was installed the exact same way, and ****, it was holding double the load. Didn't really like the idea of having to spend another 50 bucks or so for shipping back to benelli. I guess I'm a miser like that. This was to be used as a home defense gun, but I won't trust it until it can put a 1000 shells down range without a failure. I bought a Benelli so I wouldn't have to deal with BS like this. Definately not a happy buyer, expecially after I found out that the 11703 model will not properly accept a collapsible stock without some major gunsmithing. Very embarrassing to have a gun in this price range have a major failure in under a 100 rounds. -Steve [ 10-27-2004, 03:50 PM: Message edited by: stevenb ] Quote Link to comment Share on other sites More sharing options...
