I am exploring the "featureless" side of life and was looking for a way I could convert a standard Magpul MOE carbine stock into a fixed stock.
I had a few goals as part of this process:
1. I didn't want to put holes in my buffer tube
2. I wanted the stock to NOT look adjustable when I was done
3. I wanted the option of re-adjusting at my shop with the correct tools to tune the LOP
So the first thing that I did was to disassemble the existing stock which, it turned out, was very easy to do. I followed this video (even though this is the CTR the steps are basically the same):
Ok, so far so good. The stock now looks "fixed" because it doesn't have the lever to adjust it along the buffer tube. Now I needed a way to re-use the existing parts without having to drill into the buffer tube.
The plunger used to keep the stock in place as a shoulder at the top which sits in the holes in the buffer tube. Below the shoulder is a enlongated slot which is used in conjunction with a small rod and spring to make the part adjustable.
At the bottom of the plunger there is a large hole on one side and then solid on the other side. I'm not sure what the purpose of the large hole is but I decided that if I were to drill a new hole on the exact opposite side of the large hole, I could slide the roll pin back into the stock to "fix" it in place.
I used a 3/32" drill bit to drill the new hole and then reamed it out slightly to make it a little easier for the roll pin to go through
Next I put the stock back onto the lower and positioned it where I wanted it and then slid in the plunger. I used a punch to keep the holes in the stock aligned with the holes in the plunger. I held it up against a white surface (a wall) to make sure I could see through the holes to verify they were aligned before driving the roll pin home.
The final step was to drive the pin home. I would put the new hole side "up" meaning that when you drive the pin in, you will be going through the new hole first. This would make it impossible for the plunger to wiggle around after you clear the new hole and driving it the rest of the way is cake.
After you've driven the pin in, say hello to your new fixed MOE stock. You now have a fixed stock and you haven't drilled through your buffer tube. You also can fine tune it at home.
