Super M4 Posted October 30, 2008 Share Posted October 30, 2008 I have a Benelli m4 and have shot close to if not more than 2000 rds thru it. I was taking a class about 2 months ago and made it all the way through the class with no problems. On the very last COF my bolt handle flew out. Bad part is I never found it. I had a spare bolt handle one of Dave's Metal works enlarged. I'm shooting this past Sunday and just out of nowhere it flew off as well. Luckily I found it and kept shooting about 50 rds later it does the same thing again. This really sucks and was wondering if any one else has had the same problem and what should I do about it.

bignotti Posted October 30, 2008 Share Posted October 30, 2008 Hi Super M4! It sounds like the problem may not be the bolt handles since it happened to two of the bolt handles. It looks like the problem may be the Bolt handle detente or probably the Bolt handle detente spring. Look at pages 8 and 9 in the spare parts manual. PM me with your e-mail if I can help.

adamlau Posted October 30, 2008 Share Posted October 30, 2008 If your M4 is still under warranty, send the bolt group back to Benelli for inspection. Turnaround is quicker these days (I sent two M4 parts back within the last six months) than in the past. Quote Link to comment Share on other sites More sharing options...
NoTycoon Posted July 21, 2019 Share Posted July 21, 2019 I have had the same problem. It happens sporadically, I have been lucky enough to find each time. I would also like to hear of a solution. Will inspect my detente parts; however, I can pull on the bolt handle and it is tight. Some how, it gets released (falls out) during the cycling operation.

StrangerDanger Posted July 22, 2019 Share Posted July 22, 2019 I’d recommend letting Benelli fix it. That detent and spring is a pain in the ass to get back in. If you don’t have tiny 3/32 type punches, forget it. The detent May have damaged the bolt handle’s notches which would make sense if multiple handles are falling out. Or the spring could be weak or bound up and not applying sufficient pressure on the detent. Quote Link to comment Share on other sites More sharing options...
Jolly Roger Posted July 24, 2019 Share Posted July 24, 2019 Was the first bolt that flew out an OEM? None of these after market bolt handles seem to be cut right, wrong angle, too deep here or too shallow there...Mostly all of them far outweigh the OEM handle. An example of a comparison between the oem vs an after market handle here in this picture below. (my drawing from another thread complaining about AM handles) Quote Link to comment Share on other sites More sharing options...
Jolly Roger Posted July 24, 2019 Share Posted July 24, 2019 (edited) Here is another example of whats happening inside due to bad after-market tolerances... ...notice the better ball bearing detent purchase.

NoTycoon Posted July 25, 2019 Share Posted July 25, 2019 Thanks for the info. Only my after market handle has been dislodged. Let me check the tolerances. Quote Link to comment Share on other sites More sharing options...

Birdog19 Posted August 29, 2019 Share Posted August 29, 2019 Donrozon - Can you give us a rundown on your fluted bolt? Who did it? How much? Weight differences? Actual benefits in cycling and felt recoil? I see Taran Tactical offers this as part of their overall upgrade packages but never offered as a stand alone service. Losers of Bolt Handles (No Tycoon, Super M4) - For those of you that were lucky enough to find their handles, where was it? Meaning, did it appear to fly out and behind you at the end of the bolt retraction or in front of you when the bolt slammed home on the chamber? Thanks, Birdog Quote Link to comment Share on other sites More sharing options...
NoTycoon Posted August 29, 2019 Share Posted August 29, 2019 I was standing in a shooting box, and it was just outside to the right. So, it fell nearly straight down. Quote Link to comment Share on other sites More sharing options...
