The traditional M4 weighs in at 7.8 pounds unloaded. This new model with its rail and different stock weigh in at 8.4 lbs. Considering most of the new stock is polymer, my guess is most of the gain lives in that rail. I'd assume this rail is either 6065 or 7075 aluminum. So its a bit of a chonker. Looking at the rail closer, I don't think those are MLOK/Keymod sockets. It appears to have threaded holes for attaching Picatinny rail sections. In two years, I'll be at 20 years on this platform. I've been riding the struggle bus chasing a proper rail system all that time for the sole purpose of mounting a weapon light in an efficient manner. Nothing beats the ergonomics of the OEM polymer handguards, extra points if they're stippled professionally. Every rail system out there for the Benelli M4 has been poorly designed. Poor installation systems that require the use of tools to service the firearm. Terrible ergonomics where you're holding onto a Pringles can. Stupidly positioned Picatinny/MLOK/Keymod rail positions that have little to no thought process on why they are there. Failure inducing designs where the rail makes contact with the gas pistons. All add substantial weight to the firearm. All rail systems abandon the enclosed ARGO piston design that keeps debris out and gases trapped inside. This is why the IWC weapon light mount is so popular for the M4. It gets you a serviceable light mounting solution without ruining the firearm with stupid crap. Unfortunately the mounting solution isn't perfect either on 18.5" M4's. Most of these rail systems require that you remove all of your accessories from the rail in order to slide the thing off of the barrel assembly. So after you've locked all your screws in with thread locker to keep them from being shaken loose, you get to do it over and over again for general maintenance of the ARGO system.

Fetter buckshot loads seven. Several slug varieties load seven. I buy bulk stuff usually cuz I like to shoot so it’s hit and miss. It’s various unfired shell length mostly that is causing your problem, but the spring will give you another 1/2 inch or so over the factory spring.

Could they last longer? You bet! But PM matters for optimal function. Things like the extractor would be inspected closely during the spring replacement. The Ejector spring is an exception due to it's absolute pain to service. 1 drop of oil on the ejector pin, and work the plunger. If no glaring deficiency is noted, you're done with that. Same for gas cap springs, sans the oil bit.): https://www.midwestgunworks.com/page/mgwi/prod/70037 https://www.midwestgunworks.com/page/mgwi/prod/70036 https://www.midwestgunworks.com/page/mgwi/prod/70038 (harbor Freight punches here...it will be bent/sacrificed.) https://www.midwestgunworks.com/page/mgwi/prod/70030 https://www.midwestgunworks.com/page/mgwi/prod/70040 https://www.midwestgunworks.com/benelli-m4/hammer-spring.html (OOS, it will come back before you need it likely...) https://www.midwestgunworks.com/page/mgwi/prod/70057 https://www.midwestgunworks.com/page/mgwi/prod/70012 https://www.midwestgunworks.com/page/mgwi/prod/60303 https://shop.carriercomp.com/product.sc?productId=1 https://www.midwestgunworks.com/page/mgwi/prod/70021 https://www.midwestgunworks.com/page/mgwi/prod/70016 https://www.midwestgunworks.com/page/mgwi/prod/70004 https://www.midwestgunworks.com/page/mgwi/prod/70029 https://www.gunpartscorp.com/products/1439350 https://www.gunpartscorp.com/products/1439180B https://www.amazon.com/VISE-GRIP-Convertible-Pliers-2-Inch-2078900/dp/B000JNRR0Y/ref=sr_1_10?crid=17V7SVNOIFCWP&keywords=snap+ring+pliers&qid=1662453717&sprefix=snap+ring+pliars%2Caps%2C98&sr=8-10 This isn't a bad kit and may be substituted for some of the above: https://www.benelliparts.net/products/benelli-m4-essentials-small-parts-kit

Doesn't look great, but it works. Plastic shield I had lying around, for a Mossberg. Cut off the lips on the breech end, used a ranger band. 2800$ gun - $25 heat shield. ? I was going to get the briley 3 gun forends but I like the fit and feel of oem.

Naw, I wrote a long response because I literally had nothing else to do. And you're welcome for the mental image ☺️ Please explain this to me, though: I'm currently working in one of the worst neighborhoods of New Orleans. A vast majority of that is me sitting in my stationary car. The gun is on the seat so I can easily grab it if some thug rushes up on me. What good would a holster do me? What kind of advantage would I gain? What's wrong with burning stuff and drinking beer? It's relaxing for me. Sometimes I even piss in the fire ? I bet you're one of those guys that leaves comments on youtube videos of someone doesn't show the weapons clear, rack it 6 times and stick their finger in the chamber, ain't ya? ?
