Beretta Extrema2 rubber o-ring placement....

[jjdeneen918]

So, I just bought this shotgun. I put it together and take it apart. I see a small object fall to the floor and find its a rubber o-ring.

I didn't see where it fell from the shotgun and I dont see any specific mention of it listed in the manual unless it's labeled as something else.

The first pic is the o-ring.

Second pic it the part of the shotgun I believe it may go...

Third pic is where I believe it may go when installed.

I just want to make sure its in the right place. If anyone can check there gun or personally knows where it go can let me know I would appreciate it.

I do not have an o-ring there on mine.

Where the Piston (C5 in your manual) goes into the Gas Cylinder Assembly (C4) there is a green rubber type o-ring in mine, maybe that's missing.

Let me find a camera and I will take a photo of it real quick.

ETA: Okay here is a photo, this is the barrel pointed at the ground. With me looking down into the back side of the Gas Cylinder Assy.



Thanks for reminding me I need to clean mine.

Sweet, thanks buddy.

I am flying to NorCal in the morning. Shooting with the father-in-law in the afternoon. I will be reading the manual on my flight.

I'm in crazy pack clothes, guns, ect. mode now....

Any tips on the shotgun before I use it tomorrow? Oil placement advice, info, ect....

Thanks fellas.

I wish I had an answer to tips and such outside of what the manual says but I don't get to shoot mine that much so I can only offer that its a great shooter and tons of fun. I like mine a lot.

To Alieron:

So I should be inserting the o-ring into the seat of the part you have pictured?

I don't see an o-ring in the picture....

Crap I found the O-ring...

It goes in your plastic for-grip.


Look at this photo...

Forward area of the grip. There is an O-Ring (Part 22) where the plastic insert plugs in (Part 18). Sorry about the mix-up.

You need to stuff it back in there by pushing between the Insert (18) and the for-grip (17) or pull the insert out and put it back and put the insert back in.

Oh man, that was overly-complicated but simple.

That part, 18, I thought was a simple plastic bushing that came from the factory but wasn't required. Upon closer inspection, it holds the forgrip tight and has the metal pin needle that tensions the for-grip screw. The rubber o-ring seats on the bushing.

Thnak you for the exploded diagram, I would have been lost without it..

Dang semi autos with fancy complicated parts...

[jjdeneen918]

damn, I wonder what would have happened if I had been dumb and shot the thing with the O-ring placed where I though it may have been originally seated?

I would have not done such a thing without at the very least calling Beretta or contacting a gun shop familiar with Beretta shotgubs...
