Later I had local smith cut for choke tubes.

Does anyone make a Shotgun stock that's easily convertible to an AOW grip? Like some threads in the back of the AOW and just screw the stock on when you want an SBS?

Maybe just use one of these on the old wood stock?

Would that work legally? I'm pretty ignorant of the AOW rules.

Maybe it would be like having the option of quickly and easily converting an AR pistol to/from an SBR registered lower?

Maybe it is that they are a long gun equivalent of a revolver. All metal and wood, lots of fun mechanical moving parts and ussually cheap with lots of character.

I prefer semi autos. More effort to make em run right but their the cats meow.
I've done quite a few V3's from 8" up to 13". The 13" being the TAC 13 with a buttstock.
These two are awesome soft shooters. All day long at the range if you like and the shoulder won't be hurting.
11 inche barrel on the left one and 10 inches on the right. Both magazines tubes were shortened to achieve this look.
The 11 inch has a Kynshot hydralic buffer (receiver extension) absolutely not needed and it's a folder.

These are some of the others.
Top to bottom. 8", 10", 13", 11"

Live my 12” 1100

But if you got the huevos and the shoulder I'll cheer you on. Ever heard the statement "kicks like a mule"

Start with the 8" Here is the link to the complete build. Need some real machining skills or know a good machine shop.
This was a big change as the original barrel ring was totally removed and mounting/securing the barrel was a big change.
The build was recently archived to my dismay. Here is the link.

The 10" is relative easy unless you want the same look I opted for.
I shortened the mag tube and the forend to add a 1 round extension and to use the barrel clamp.
I use my printed adapter to mount the Raptor grip or the Magpul SGA stock on all of my V3 builds requiring it.
Here is a link to the build.

A few pics with the tape

Front face of the barrel ring is 8" from closed bolt face. Compensating plugs converted to straight plugs.

Here you can see the hanfguard is too long and requires shortening.

A view of the mag tube. If left as is, cut the barrel to accomodate the finished length with mag cap.
These two pics are of a wood furniture gun with gas tubes instead of compensating plugs or plain plugs.
The mag tube is a bit longer than 10 inches. My 10" is closer to 10.5 inches.

Thinking of chopping a 1100.

The 1100 is a different animal. Depending which model you want to shorten.
The magnum models usually only have a single gas port. Usually off to one side leaving the other side open for a second port.
A second port can be added if the SBS design (barrel length) requires it and it probably will unless you plan on shooting high velocity ammo like 1500 or 1600 FPS loads.
A standard 1100 trap or field grade has two ports. Don't remember the exact size but that is not really an issue. Address later.
The ammo is kind of important. Depending on what you want to shoot. The actual load is what's important. Example:
I set up all my 12 gauge SBS's to run 1200 FPS, 1 1/8 oz load, 3 dram powder equilivent. Also 1200 FPS 1oz slugs/00 buck.
I don't use white box ammo from say Walmart or other big box stores with the same ratings.
I find them to be inconsistant with the loads and have verified with a chronegraph.
So how short would you like to go. Without major work, your minimum is going to be around 12 inches barrel length.
There are several 1100's on this site setting at 12 inches.
A 12 inch with 1200 FPS, 1 oz loads will require slight opening of both ports. Might be as little as one drill size but could be a bit more.
Important: You need to start with a completely cleaned oiled 1100. Including the action spring in the buttstock. I make sure there is nothing to inhibit cycling.
This is where to begin the process to discover the port sizes.
If you can't keep the chosen ammo you set the gun up for, take along several manufacturers with that same 1200FPS, 1oz load specs.
You can test them all with your initial set-up. You may find that one brand is better and one brand is worse for cycling. Not uncommon to find this.
If you choose the worst ammo for cycling, let that be what you use to do the final testing and final port sizes.
That will allow you to shoot all the others you might buy to use in this SBS.
I have a 14" 1100 that I opened the ports one drill size and it runs anything in that 1200FPS, 1oz load shells.
Note: 1 oz slugs will run when 1 oz shot won't! Can'r really give a prove explanation as to why.
If your going to run hotter ammo all the time you probably will not have to open the portts at all.
I have a 10" 1100 that was a lot of work. Moving the barrel ring and shortening and lightening the slide had to be done.
It runs without issue with the 1200 FPS loaded ammo. Port sizes are one drill size up in diameter if memory serves me right.
Thats possible because the barrel ring was moved about 1.5 inches closer to the chamber creating more dwell time with that really short barrel.
The other part of it is that the slide has been shortened and made substantially lighter than the stock part.
Here's the link for my 14" 1100.
