frolic1 Posted October 21, 2009 Share Posted October 21, 2009 The M4 manual online at the Benelli site states that the magazine holds 6 shells. I assume that's 6 +1. Does anyone know whether there is a limiter installed? Or does the stock M4 sold in the US really hold 6 shells. Quote Link to comment Share on other sites More sharing options...
tinman1975 Posted October 22, 2009 Share Posted October 22, 2009 (edited) the stock configuration M4 is listed as 4+1 here on the benelli site. You can actually fit 5 shells if you are using 2 3/4". Its not that there is a limiter inside the tube...the tube just ends where you see that funny little plastic lookin part on the last 1/3 or so of the tube. So realistically a stock M4 can hold 5 +1+1 if you float a shell on the carrier Edited October 22, 2009 by tinman1975 Quote Link to comment Share on other sites More sharing options...
zee10103 Posted October 22, 2009 Share Posted October 22, 2009 My M4 was 5+1 Quote Link to comment Share on other sites More sharing options...
frolic1 Posted October 22, 2009 Author Share Posted October 22, 2009 Thanks for the info. I plan to use 2 3/4" shells so 5 in the mag should be adequate. Quote Link to comment Share on other sites More sharing options...
sneakerfreak602 Posted October 23, 2009 Share Posted October 23, 2009 Thanks for the info. I plan to use 2 3/4" shells so 5 in the mag should be adequate. You can get the mag extension or a full tube and hold 7+1. Just in case you encountersome zombies or live in Phoenix like me where every morning we hear of some home invasion on the news. I also have a buttstock nylon side saddle. Call me paranoid.lol Quote Link to comment Share on other sites More sharing options...

jon.benton Posted October 24, 2009 Share Posted October 24, 2009 Thanks for the info. I plan to use 2 3/4" shells so 5 in the mag should be adequate. It is a physical impossibility to have a shotgun that holds enough shells. Quote Link to comment Share on other sites More sharing options...

deek57 Posted December 10, 2019 Share Posted December 10, 2019 I recently got an m4/mag upgrade and dealt with the 6 rounds problem. I could only fit 7 with target loads, 6 with everything else. I'm spamming the top googled threads with this reply because got sick of being told it's about shell length and unfixable, or I have to cut my spring to fix it. I could never find a thread that just gave me a clear answer about an easy spring swap or anything else that worked. I'm blown away by how hard it was to find a clear answer on this simple topic. The fix? I replaced the factory spring with a wolff m4 spring from freedom fighter tactical and it went from being a half inch away from holding 7, to holding 7 of anything 2 3/4" long. It's tight, but mine holds 7 of everything now. This isn't meant to be an ad for wolff, as there may be others out there that would fix the problem, but it worked for me and should for you. Non-target-load 2 3/4in shells are longer and that's a fact, but assuming your m4 parts are the same dimensions as mine which they should be, your M4 WILL hold 7+2 if you get the spring replaced. I hope I can bring a few people's blood pressure down if you are dealing with the same problem and as frustrated as me with the threads full of non answers out there.

CobraBG Posted December 11, 2019 Share Posted December 11, 2019 Good to know, thanks. Like you, I've read a lot about this. I've used Wolfe before on other weapons now I'll be looking at them for my M4. Quote Link to comment Share on other sites More sharing options...
bdickers Posted December 13, 2019 Share Posted December 13, 2019 (edited) Has anyone installed the 2 round extension on the M4? Do I need to remove the snap ring and whatever lies beneath it? Edited December 13, 2019 by bdickers Quote Link to comment Share on other sites More sharing options...

If you install an extension then that retainer would need to be removed so that the spring can seat into the extension. You would likely need a longer spring.

NineInchNails Posted December 13, 2019 Share Posted December 13, 2019 Like many, I prefer a full length magazine tube as well as a side saddle/shell carrier. I'm completely satisfied with the full length tube. Adding an extension doesn't interest me. Here's why. Whenever I shoot the M4, or any shotgun, I am continuously practicing loading shells. It becomes nearly automatic after a while. When I'm not firing, I am reloading, even if it is only one round. That to me is more valuable than the initial number of shells in the magazine tube. Shooting clays gives you a good opportunity to practice reloading. Quote Link to comment Share on other sites More sharing options...
Morton Posted April 19, 2021 Share Posted April 19, 2021 (edited) There's a bit of misunderstanding about the shell size and how many the M4 can load. If a shell is billed as 2-3/4" shell, that means that after it is fired, the plastic (or paper) left over will be 2-3/4" long from the base of the shell. For instance I have some Wolf 2-3/4" shells with #8 shot in them and they are exactly 2-1/4" long before they're fired. My M4 is a model 11701, a 5+1+1, and I can load 5 of these in the magazine. I also have some Nobel Sport Italia 2-3/4" #4 buck and those are almost 2-1/2" long before being fired. I can load only 4 of them in the mag. A "special" spring might let you load a slightly longer shell, but it's not really about the spring, it's about the ammo. I can actually load 4 of the 2-1/4" long Wolf bird shot shells and one of the 2-1/2' Nobel Sport Italia #4 buck without 1/8" to spare. But both are called 2-3/4" shells, and that's where so much misunderstanding comes from. I'd like us to start a sticky thread where we can register different brands of ammo and have the exact sizes listed so we can choose ammo that will fit the stated mag sizes. As I alluded to, it seems the 5 shot tube on my model 11701 will hold a total of 11-3/4" of shells or 5 shells just a shade over 2-1/3" long each.

Do I need to remove the snap ring and whatever lies beneath it? The 2 round extension will require you to remove the "snap ring", which is more of a spring sleeve, and installing it onto the end of the extension tube. Disassembly will then necessarily involve releasing the magazine spring every time you remove the barrel. I actually prefer this setup because I can completely clean everything except the bolt return spring without needing a tool kit. One of the great things about the M4 is the ability to field strip and clean the weapon using only the bolt handle as your "tool". But it never allowed cleaning the magazine tube or the bolt return tube without snap ring pliers. With my 2 round extension tube, I can at least clean the magazine tube now. The 7rd tubes are getting hard to find and they're quite expensive. As far as I can see the only reason to get one would be either for cosmetic reasons or to not have to deal with the magazine spring, which is not a big deal anyways. But the best reason I have for using the 2rd extension tube instead of getting a 7rd tube is for camouflage purposes. (?) Here's what you do: Paint stripes on it to look like the stock tube you have now. A knowledgeable terrorist will see it from a distance and think to himself, "That guy has a maximum of 7 rounds before he has to reload.", when in fact you have 9. heh heh Quote Link to comment Share on other sites More sharing options...
