Benelli M2 Cycling Problems

Postby Jonny Cormie » Fri May 02, 2014 2:24 pm

Hi All,

Recently started having issues with a Benelli M2. It was previously very reliable and would cycle anything I could throw at it, it's now being a total pig and appears to fail to eject fully, the empty case often getting caught between the bolt and the ejection port (not stovepiping, the case is side on).

The gun's been cleaned and lubed and the only modification it's had is to the shell stop where we've cut notches in it to decrease the tension.

Am I missing something really obvious? Has anyone else had this issue?

Hi Johnny,

First make sure it is lightly lubed - not too much. Next try someone else's mag spring. My reliable M2 has only ever had issues with the mag spring and on very cold days!

I am no expert on the M2 and I am sure further advice will follow.

Good luck.

John,

Yeh, the mag spring can cause malfunctions if it is fatigued, as can the recoil spring if it is losing its tension.

Also check that the little spring-loaded ejector is still in place and the spring is ok.

I agree with Andy, this is the likely culprit.

Check it is free to move & not all bunged up with gunk.

Here is a picture of the plunger in its place on the barrel extension.

Thanks for the replies guys, I'll have a look tonight and see what condition the ejector's in. I'll be chuffed if that's all it turns out to be!

Is it a gunsmithing job to replace these parts? There seem to be two rivets holding the ejector assembly onto the barrel which need drilling out and new ones pressed in. Is that right?
