I finally picked up my new M4 model 11703. It has IT23 on the receiver. Is it a Gen 2? thanks

I love PMC high velocity #4 buck. It is very spicy and shoots well out of my m4.

Benelli is missing out on a market for the M4 comfortstocks and wood stocks!

Smaller shot size such as #4 buck is preferred for safety when one is concerned about barrier penetration. IMO that’s the only reason for using #4 buck, it just doesn’t retain energy like 000 or 00 buck.

Personally I’m a huge fan of 000 buck however at five yards just about any 2 3/4” rounds of 00 buck won’t disappoint. 3” shot shells are a waste of money and magazine space IMO. Typically a shot pattern opens up about 1” for every yard traveled so at five yards the shot pattern will be about five inches in diameter.

The three notches, or stars, means it is a Modified Choke. Yes, you can shoot slugs from your modified choke. You can use pretty much any type of 12-gauge 2 3/4-3" ammo through this choke.

I took a couple pics below for those wanting to see it. I like it A LOT. They are well made and super easy to get on target with. Couldn t be happier with it

This thing is easy to take apart and put back together like in 60 seconds;)

Machinegunners lube from LaRue. It's cheap and it works great. It stays where you put it. The failure you are seeing is anemic ammunition. The bolt carrier barely opens fully before closing. If the bolt carrier doesn't open fully, it doesn't hit the ejector that is on the barrel assembly. A weak hit on the ejector leads to this type of failure where the bolt closes on a spent shell before it is fully ejected. Your bolt carrier link and rails should be slathered with oil. If the weapon is fairly new, it should be broken in with some high dram shells. Cool videos!

All birdshot should fire fine. Question 1) - How many rounds are through your gun? 200+? Question 2) - Is your bolt carrier drenched in lube? Like literally, drenched. I've come to believe that failure to reliably cycle birdshot comes from one of these two factors, each and every time it comes up on these forums. My first M4 wouldn't cycle anything reliably for the first ~150 rounds. Buckshot, slugs, birdshot ... it would fire 3-4 rounds and have various jams on the next. It didn't have a drop of lube on it, as I was a newb and I didn't figure it would matter. 12000 rounds later now and I've yet to have a single malfunction after I lubed up the bolt carrier. I've cleaned it probably 4 times in all those rounds. Between 3 friends and myself, after my initial "dry" m4 fail prone firing, we have purchased and broken in 4 M4's between us. Each of them has been 100% flawless out of the box with every type of ammo, because before initial firing we slathered machine gunners lube or another dedicated high temperature gun oil on the bolt carrier and recoil spring. Member "Unobtanium" on this board has been through 3, maybe 4 M4's by now, and each has been 100% out of the box as well because he knew to properly lube. As such, every thread I see that related to this topic I've somewhat concluded boils down to these two things, plentiful lube and 200+ round count to make sure an overly tight tolerance isn't causing friction based stoppages (unless something is catastrophically wrong, which I have yet to see). So I ask, how many rounds are through your gun? And is the interior recoil spring, bottom of the bolt carrier and receiver rails slathered up with oil AT THE TIME OF THE SHOOT? Cleaning and oiling with CLP a week prior to shooting often leads to a near completely dry gun at the time of the shoot ... as many multi purpose or cheaper oils evaporate at room temperatures or as soon as they start to heat up. Oil right before your shoot, proper lubrication is 100000x more important than cleaning when it comes to this gun (and most other guns, for the matter). If you have 200+ rounds through your gun, and you're lubed up, you should be able to burn through any brand of standard birdshot rounds without any issues. If not, detail the issue here and see if we can diagnose it.
