Upgrading/modding my Benelli M4

Celt · May 9, 2025

Ive been eyeballing a 1301 myself, but thats a future purchase. I love the m4, but with everything ive read about the 1301 i think id buy that before the m4.

I’ve been wanting a 1301 myself but I’m too cheap. It’s probably too late but maybe worth some consideration but the Mesa Tactical urbino stock worked out great on my M4. It made me fall in love with it. It shortened the length of pull perfectly for me.

I had a chance to buy an M4 for $700 but I didn’t know what they were worth. It was all decked out for shooting competitions and I wanted one for hunting. During the pandemic I noticed they were going for $2,500 so I was kicking myself for not buying and selling it to make a profit.

I like your list of mods. I thought a collapsible stock was not allowed on a semi-auto shotty, and the forward grip is evil, too…. What am I getting wrong here?

~~Doesn't that only apply if you have a removable magazine?~~ Also, that is technically a hand stop.

I guess I'll pin it at the LOP i want it, but make it so I can reverse the changes (if I move). I'll probably tap a small hole and rivet it in place. It should be easily reversable by drilling it out.

NYS sucks. The amount of crimes committed with shotguns is so extremely low it’s not even funny that they included this. Someday maybe it will get overturned.

Shotguns are considered assault weapons if they are semi-automatic and have any one of the following features:

A folding or adjustable stock
A thumbhole stock
A foregrip or second pistol grip
The ability to accept a detachable magazine, or
A fixed magazine with a capacity over 7 rounds.

You can use a spring pin.

Like a roll pin?

Same thing.

Drill a hole slightly smaller diameter. Cut the roll pin to the depth of the hole, then press or tap it in.

The shit we have to go through to make sure we aren't committing a so-called crime is ridiculous.

Not only compliance with NYS laws, but Federal compliance with 922(r) by increasing round capacity to 7. Assuming that you would be covered since BRM is US company manufacturing within the US and I don't believe there has ever been a prosecution based on 922(r) non-compliance.

Without knowing how you originally purchased the M4, you would be covered with the following US made parts;
Magtube
Pistol Grip
Buttstock
Forearm/Handguard
