Win Mod12 Trench Gun Conversion

"The slide sleeve cap apparently had some strange, sloppy work on it and I wonder if anyone can shed some light on what and why-"

It's damaged. Not sure how or why. I'd buy a replacement. You can probably find one on eBay for $20.

is this the cap you need? Not mine...but on E-Bay...

Should be a learning experience for all of us!
Once I have the shield-stub in hand and get precise dimensions, I should be able to scaled off of pictures on the internet for the flared end.

It won't be perfect, and forming the round shape from the laser cut flat won't be easy, but it'll be interesting!

I'm happy to lend a hand on an interesting project like this!

PM sent.

It looks like you appreciate a challenge which I can appreciate as well - thanks Ryan

I found it very curious and surprising but will try to find another as well as a replacement mag spring...

Before I order another magazine spring - do know if the trench gun spring and tube are same length as the commercial guns??

The military guns were made from civilian guns so I’m sure the springs and tubes are the same length.

Is the magazine spring and tube the same length for commercial and military trench guns? Been looking for a replacement spring with surprisingly little luck. I did find a replacement stainless spring made by Wolf but before I order I want to be sure....I'm leaning more to converting this 12 to a trench gun I think.

Is this 12 Ga "New Factory Original, Vintage" spring OK to use ....? The eBay seller laid it out sorta straight after a request.
I need a replacement....

The military guns were made from civilian guns so I’m sure the springs and tubes are the same length.

It finally dawned me that I had aM97 Riot Gun - the M97 Riot military tube measures 16" compared to the commercial M12 tube that measures 17".

Not sure if the difference is significant since they're two different year models.

I shortened my M12 trench magazine in order to get rid of the takedown pin holes. I honestly don’t know how the real trench guns were done. Guessing they would pull the mag tubes from the line before drilling any holes and fit the endcap with the bayonet mount pin. Any 12 ga magazine spring should work. I wouldn’t buy one thats already kinked up, get a new ss one and trim it.

Seriously, I have a couple here I think that would work. Just about anything 12 ga will do.

Thanks all for the help and information. I'm going to a gun show this afternoon and if I can find one I'll let you know, if not and you have a spare I'd be happy to accept your offer.


Thanks again -
