Benelli M1 barrel fit problem? Atlanta benelli smith?

[cguy1177]

I recently bought a used M1 field 26" barrel to use in 3 gun and

then found someone to trade for his 21" barrel.

I sent him my 26" and forearm and he says they fit fine.

however, when I try to put his 21" barrel on my M1, it will not

seat all the way. something is stopping it short. It looks

like perhaps the barrel is just a hair too large? and it's

hitting on a short support groove?

He says his M1 is about 20 years old. The one I have is not that old

but I'm not sure of its exact age.

Does anyone have any ideas or suggestions? I'd like to get the 21 to

fit if possible. especially since the alternative is to eat all the shipping

charges and trade back for the 26"...

Not sure......others know more, but I vaguely recall something about the plastic on foregrip needs a little trimming?

Figure out where the interference to fit is located.

yes, the forearms are different so we swapped those too.

I think I see where it's stopping. I'll try to post a picture

later on today.

Went over to a local gun shop this afternoon and when I was telling

the gunsmith about the issue he asked the local Benelli

rep. to take a look since he happened to be in the store.

Both agreed where the stoppage was happening and the Benelli

rep said to give Benelli a call later when they were open

( closed for the snowstorm apparently ). The gunsmith said

he would choose to take material off of the chromed barrel

first before taking anything off the anodized aluminum

"support lug" but said to see what benelli said first.

so I guess I'll see what they say when the snow lets up; though

I'm not very hopeful given its a used gun with a traded barrel......

I had the same problem...I traded the barrel back since I didn't want to fight it.

Hope you can work it out...I know the feeling.

RLTW,

It's really hard to tell what is going on there-the pictures are really big. Maybe just take a couple of long shots with the foregrip from the bottom and at the barrel-receiver lug interface. Is it jamming into the receiver or is the foregrip stopping it from seating? The foregrip washers sometimes need adjusting. Does the barrel fit without the foregrip on? Benelli is in for another storm. May take a while to get information.

Thanks Jade but it looks like the barrel receiver interface :-(

Tried it several times without the forearm ( like it was all of a sudden magically work...hah )

Left a message today, we'll see when/if they open this week!

Might have to trade back barrels and have the 26 cut down by Carlson I guess.

[RiggerJJ]

Just run the 26, thats all I use...

UPDATE:

So I was getting ready to just trade back the barrel when Braxton1 offered to take

a look at it and we got to meet at the South Atlanta PSC weekly shoot last night.

Bruce carefully examined it, gauged the exact tolerances and quickly applied corrective

measures...and the barrel seated! Then a quick test fire sequence on an unfortunate target

and all is well.

Looks like I am all set now thanks to Bruce, without his help I would have been stuck with

numerous shipping and other costs and ended up back with my 26, though usable, not my preference.

Thanks Bruce, for doing what 2 gunsmiths and 1 local Benelli representative couldn't!

What was the interference/fit up issue and what had to be done to fix it?

Yeah - what was the problem and what was the fix?

Inquiring minds want to know

Actually it was straightforward and simple. Bruce determined that

there was no direct blockage from the front edge of the barrel

and that it was close enough to try a force fit. So he simply

removed the carrier to be careful and then used the floor to

help press the barrel in to see if it would go past the 'swell'

of the chrome part. It did. So the chrome part was just a

hair thicker on the older m1 barrels apparently and can be

carefully force fitted. I've worked it back and forth now several

times and might file it slightly but it works fine.

I was shaking my head that between 2 gunsmiths, a benelli rep and

myself we hadn't seen that and tried it more forcefully but we all

stopped at the first heavy resistance. I guess if it's built to

handle thousands of psi of pressure then it can handle a pretty

forceful pressing against a floor, but everyone except Bruce was

babying it.

So, in other words you kinda sorta just needed a "bigger hammer"
