shuter Posted January 22, 2010 Share Posted January 22, 2010 Hello all, first post here. Am looking at new M4 at local dealer. Seems like I heard a few years ago about problems with M4 "bolt carriers" cracking, and having to use low pressure shells? Maybe I'm remembering wrong. Does the current generation M4 have any durability issues such as these? Has Benelli made any changes to the design since inception? Thanks so much in advance for your input. I like the ability to customize these as well. Kinda like a shotgun version of the AR! There seems to be an entire cottage industry that I wasn't aware of. see ya Quote Link to comment Share on other sites More sharing options...
StrangerDanger Posted January 22, 2010 Share Posted January 22, 2010 That was related to the 4 port barrels that originally came in the 11703 model. Benelli has replaced those barrels when requested. All current production models are 2 port barrels. The easiest way is to be sure the weapon you're purchasing is a 11707 or an 11717 (tan).

shuter Posted January 22, 2010 Author Share Posted January 22, 2010 Awesome. Thanks very much. This is a new production gun, so I'm sure it's the 707. Quote Link to comment Share on other sites More sharing options...
Hookster Posted January 22, 2010 Share Posted January 22, 2010 Awesome. Thanks very much. This is a new production gun, so I'm sure it's the 707. Note: Just so you know, It wont say 11707 anywhere on the gun but it's on the end of the Benelli box that it comes in. On the label with all the UPC codes.

Duggan Posted January 23, 2010 Share Posted January 23, 2010 A 2 port m4 with adequate lubrication should be flawless in function and more durable than you are. Quote Link to comment Share on other sites More sharing options...
xamoel Posted January 23, 2010 Share Posted January 23, 2010 damn, i threw away the benelli box, but i still have some stickers with code on it, 3 saying CANNA and 1 saying CARCASSA. couldn't find a "707" anywhere on it though. isn't there a way to get the manufacturing date from the serial number?

Yeah, Look for the small square with two letters in it stamped in the receiver near the trigger guard. The date chart Tucker posted is in post #2 of this thread http://www.benelliusa.com/forum/showthread.php?t=19454 2009 which is not listed is "CD" Later, Hookster Quote Link to comment Share on other sites More sharing options...
xamoel Posted January 23, 2010 Share Posted January 23, 2010 (edited) awesome, thanks! €: it's a 2009 model, good to hear. but it seems as if the stamp has somehow chopped of the finish, you can see silver pieces right there.
