Benelli M4 Stock Removal Problems

[notrabmas]

I'm trying to remove the stock on my Benelli M4 to change it to the Urbino stock, but no matter how hard I try and screw off the stock, it won't budge. Any advice? I know I'm turning it the right way and I have it completely stripped besides the stock.

Leverage is your friend. With the trigger group removed, it will unscrew with enough leverage. A padded vice can be used or maybe solicit a friend to assist. Try twisting from the bottom of the pistol grip to maximize your leverage.

I tried with a friend and it didn't even budge. I'll have to try the vice tomorrow morning. Was it this hard for you?

The Trigger Assembly must be removed.

 

After that, I've never had an issue. Removed many of them.

I removed the trigger assembly too. Mine must be on super tight.

I dont remember this step being an issue, wonder if there is some sort of thread lock. I know the mag tube has it, but I cant imagine anyone thinking thread lock on the stock is a good idea.

Threadlocker isn't likely since the pistol grip stock attaches via the stock retention screw at the bottom of the receiver extension.

 

Someone just likely hulked it on. Be careful using the vice. I would assemble the weapon so that the bolt carrier and the barrel are installed. This will add rigidity to the receiver. Just pull the trigger group.

 

I would clamp the receiver in the vice upside down below the rear sight. You don't want to squeeze the receiver very hard in the vice. The aluminum will deform under pressure. You want it tight enough so it doesn't move and damage your finish.

 

Set it so you can push on the pistol grip counter clockwise to loosen the stock. The ability to lean against the grip will help apply enough torque to loosen it. You can also try using a rubber mallet. Whack the pistol grip. Put a rag or a towel over the grip to prevent the rubber from the mallet from transferring to your weapon.

Thanks for the advice everyone. I'll try it again tomorrow.

Not meaning to be pedantic or an arse in any way but you are turning the stock the correct way and not tightening it, right?

Turn the stock counterclockwise, right?

[StrangerDanger]

Correct. Assuming you're looking at the stock from the butt pad.

I just did mine last night, it's tight. You do have to take the trigger assembly out. There is a video on the Benelli web site for the M4. It covers assembly, disassembly and change the stock.

A strap wrench might give you more leverage without risking damage to your stock.
