Yet another 10/22 project

Fri May 19, 2017 6:58 am

I know, I know...it is a sickness....I can't help myself.

I saw this gun on another forum and decided I wanted to build one.

Image

I won't be going the SBR route (unless of course they are removed from the NFA.. ).

The guy who built the one above used wood for the pistol grips and butt stock, I decided to use plastic for the pistol grips and aluminum for the butt stock

I'll adapt an AR or AK grip for the rear pistol grip
I'll install a picatinney rail and add a folding forward grip
I'll make the butt stock from aluminum tubing
I'll also make the butt pad from aluminum, but cover it with a flip flop for comfort
Free float the barrel and anchor the rear of the receiver using a bolt going through the stock and rear trigger pin hole.
Square off the stock and perhaps add some metal plates with bead rolls to the side of the stock to give it an "Uzi like" appearance?

For those that haven't seen the blog posts, I will document it here as well

blog post: http://tincanbandit.blogspot.com/2017/0 ... art-1.html

I picked up this used, 1995 vintage 10/22 for a reasonable price. The barrel has some light rust and the receiver has some chips in the paint.

Image

I wont use a good stock, I'll pick from my collection of beaters

Image

I already found a rear pistol grip, it is a universal style (to fit AR and AK rifles) and it didn't look like anything factory, which is what I wanted.

Image

I'll use the Tapco anchor and bolt along with a sling plate to mount it to the 10/22 wood stock.

Front grip will be a folding style, mounted with a short length of picatinney rail

Image

Image

I found the aluminum tubing on ebay, a 24" piece was just over $5. It has a 1" OD with 1/16" wall. It is 6063 T5 aluminum, which should be more than strong enough. I'll find some aluminum in my scrap pile to make the butt plate out of

Image

While trying to find a way to attach the butt stock I came across this part in my parts bin, it is a Aero Precision barrel nut from our AR-10 Project. It was damaged and we had to replace it, but it will work perfect for this project

Image

Image

The inside diameter of the barrel nut is almost exactly 1" and the aluminum tube slid in with the right amount of resistance.

I can use the gas tube holes run screws through to the wood to anchor it and the 8 set screw holes should sufficiently hold the lightweight butt stock .


I purchased some 8-32 set screws to hold the barrel, as well as some 10-24 x 2.25" long screws and nutserts.

Checking the length of the 10-24 cap screws, they will need to be shortened

Image

Checking the fit of the grip and sling plate

Image

Here is the stock we plan on using, you can see it is a little beat up.


Image

Using my Hoplophobe project stock as a guide, I measured 17" from the barrel band notch, marked a line and cut the butt stock off...the first cut is always the hardest

Image

Image

I also marked the stock for what I though was the most logical place for a forward grip and cut it.

I measured the stock and found it to be just shy of 2" wide (1.91"-1.94") and about 2" tall (from bottom of stock to the top of the back part of the receiver. As you can see it tapers pretty quickly at the grip, I will cut most of the remaining grip off and replace with new wood.

Image

I cut the stock back a bit farther and also cut out some Pine trim boards that are 2.5" wide by 3/4" thick, I cut into 2 x 2.5" sections then glued to the stock. This will be the base for the barrel nut to (which is 1.8" across).


Image

Then I roughed up the surfaces and glued them together

Image

Now that we have the stock cut and the new wood glued on, time to start fitting the pieces.


I measured the distance from the trigger face to the rear of the grip on my 10/22 ATI stock, it is about 2 1/2"

Image

I attached the grip anchor to the sling plate using JB Weld


Image

Based on my measurements taken from my ATI stock, I marked the area I needed to inlet

Then removed the wood

Image

JB Weld was again used to attach the anchor and plate to the wood. I put some clay in the end of the grip anchor to prevent the threads from getting sealed up

Image

First round of body filler, not for looks as we will be covering the the stock with aluminum panels, but I want the panels to have even support

Now we will focus on the construction of the butt stock and its attachment


Starting with the anchors for the butt stock, I clamped the barrel nut in place and drilled the first two holes

Image

After countersinking the holes, I put some clay in the nutserts to protect the threads, filled the holes with 5 min ClearWeld epoxy and gently tapped the nutserts in place

Image

After the first 2 anchor holes cured, I installed two of the bolts in the new anchors (for proper alignment) and drilled the last two holes.

Image


Then repeated the process

Image

While the epoxy was curing I shortened the bolts to the correct length

Image

Once the epoxy cured I did a trial fit

I started on the butt plate. I cut this piece from some 2" wide x 1/4" thick aluminum, I used a template to trace an arch

Image

Then used the belt sander to round it off

Image

After sanding and radiusing the edges, I glued a piece of flip flop to the plate

Image

After it cured, I trued up the two using the 400 grit belt on the belt sander

Image

Then I started figuring a way to connect the butt plate to the stock tube. I don't have access to a heliarc welder and didn't want to bother with trying to solder it, so I decided to use JB Weld. I stuffed some paper in the end of the tube to stop the JB Weld from running down inside.

Once I gooped it up good, I joined the two and pushed the paper down against butt plate, forcing the JB Weld against the butt plate.

Image

Image

I mixed up some more JB weld and forced it into a small syringe.

I then carefully spread it around the joint, cleaning up an mess with acetone and a cotton swab

While the JB Weld was curing, I started on the front picatinney mount. The 10/22 stock has a rounded bottom, I'll need to flatten it out some

Image

After some work with the file I marked the center line

Image

Image

Then I drilled the holes and temporarily mounted it, the bolts will be trimmed after I figure out how to use them to secure the barrel shroud as well.

Image

here it is with both fore and aft grips and the butt stock in place

Very cool, Casey. I love seeing this type of stuff.

Thanks guys!, I just posted part 3 to my blog (which is lagging behind the posts here)

http://tincanbandit.blogspot.com/2017/0 ... art-3.html


here are some more updates

I need to shorten the barrel and recrown the muzzle. By law a rifle barrel must be 16" or longer (unless you file with the BATF and get a tax stamp for a Short Barrelled Rifle). The barrel on a standard 10/22 carbine is 18.5", so I will cut 2" off the end.

Image

after cutting I checked the barrel length (with a cleaning rod in the bore) and we cam out just shy of 16.5"

Image

Using my dove tail jig, I flied and sanded the end of the barrel so it was smooth and square

Image


I then used my drill and a ball mill to chamfer the crown


Image

I then removed the chatter marks with a brass stove bolt and some valve grinding compound

Image

I stuffed a patch in the end of the bore to keep the valve grinding compound from getting inside.
