My M4 only comes with one choke, with a III symbol and I think it is the modified choke. I am thinking of shooting slug. Can I use this choke? And also, where can I buy other chokes for my M4. Any Canadian dealers selling them? Thanks for any help!
 
It's modified. Slugs are fine in any choke, including full. Lots of places sell chokes....should be the same as most benelli chokes. Wholesale sports or any of the sponsors should be able to get you chokes.
 
Your good to go for slugs...
The m4's design was geared towards slugs and high recoil loads, and you will find that it may not cycle the lighter stuff until it's broken in. No need to change the choke.
 
Another dump question. Is my M4 using smoothbore? I went to buy some slug today and the sales person asked me. But I do not know. I read the manual and no where it is mentioned. Thanks for the help again.
 
It's smoothbore. The other option is fully rifled - benelli m4s don't come with rifled barrels. You can get a rifled choke tube which will allow you to use sabot slugs. You can use them in smoothbore, but they won't spin, which it what gives them stability.

Oddly enough, rifled slugs are for use in smoothbore barrels. The slug has spiral grooves in it, which impart spin, since the smoothbore can't.
 
Look at the inside of your barrel, does it have rifling grooves or is it a smooth barrel? This is what they were asking you.
 
Benelli M4's are smoothbore, so you want to use rifled slugs only.

Many M4's, mine included, will not cycle low recoil trap loads untill you put a few hundred shells through it.

I find that the Birdshot shells that give me the best results are 3 Dram or higher for breaking it in.

Rifled slugs do not spin. The get their stability from being nose heavy. The "rifling" is there to allow them to swage down to fit through chokes. Without it, they'd either pop out in any direction, like a musket, or get stuck and cause the barrel to burst, depending on the degree of constriction.

Well I guess I learn something every day! I really thought they were rifled for spin, but your explanation makes sense too. :)

If you tear down and fully grease (not oil) your M4 internals off the batt you will have no issues cycling low powered loads in the break-in period. After that first 100-200 rounds it won't matter after that.
 
Another newbie but urgent question. Someone had disassemble the gun and I do not know how to assemble it back. The part I have problem is putting the Axle bush, 266J (Retaining ring), 267J (retaining spacer) and 268J (retaining spring) into the receiver assembly. I do not know how to fit the 3 parts to the bush. Please help. I know I am dumb but I am not the one who disassemble it. I bought the gun from someone who replace the whole part to attach a shotshell holder, in which for me I do like the model. Anyway, please help me!
