    Default How to pin a Magpul ACS Stock

    Living in MA, we need to pin an adjustable stock so it can't be moved. I pinned my Magpul ACS stock and it seems to work just fine so given the lack of instructions I found I figured I'd share how I did it. This will work for a Magpul CTR stock, and probably a MOE, but I don't have a MOE to look at.

    ADDED PICS OF CTR STOCK PINNED THE SAME WAY. Sorry!

    It is surprisingly easy to do! Do this at your own risk!

    What you need to do this:

    You will need some blue (removable) loctite to re-assemble the butt pad, small tubes are available in auto parts stores or Home Depot etc.

    A roll pin. 1/8 or smaller and the right size drill. I used a 1/8" (0.132 - 0.134") roll pin for a trigger guard that I didn't use for building this rifle. Home Depot or Lowes has roll pins.

    A SHARP Drill appropriate for the Roll Pin Diameter (I used a 1/8 Drill)

    A roll pin punch for the roll pin you are using (I used a 1/8 Roll Pin Punch)

    Hammer

    Hand Drill or Drill Press (preferred) - I used a hand drill, but my nickname used to be "Human Drill Press" YMMV!

    INSTRUCTIONS:

    Adjust the stock to your preferred (FINAL) location.

    First you have to remove the butt pad using an allen wrench. Put pieces aside.

    Then pull out the end caps for the storage tubes and let them hang.

    Slide the storage tubes all the way back towards the butt pad.





    Use a large flat head screwdriver to gently pry the tubes off of the stock, pry from around the release lever area. They should pop right out.



    Remove both storage tubes the same way and put them aside.

    It looks to me that the best place to put the pin is right between the locking lever and the release lever.



    Drill your hole right at the top/middle of the flat area so you catch both sides of the stock and the buffer tube rail. It should look like this:



    Place your roll pin into the hole and drive it in using the appropriate roll pin punch.





    Drive the pin flush with the side of the stock.


    Put the storage tubes back in and slide them back into the locking grooves. I used the corner of the bench on the bottom and pushed down on the stock.

    Put the butt pad back on and reassemble with screws. Be sure to put some blue loctite on the screws or they will come out again.



    Afterwards, you can't tell it's been pinned (other than you can no longer move the stock).



    All back together, pinned and MA compliant!



    I have another rifle with a Magpul CTR stock (This is a fantastic stock) that I pinned the same way. Here are some shots of the pinned Magpul CTR stock using the same 1/8" trigger guard roll pin from an LPK. You can get 1/8 roll pins at Lowes or Home Depot.





    Here is the Delaware lower with TacSol 22 upper with all magpul furniture. I like.

    Nice job... at least it won't be that hard to undo when you escape MA (or you can "reassign" the stock to a preban lower).

    Yea, it is definately easy to undo if the state gov comes to its senses about these moronic AWB laws. They haven't helped anything.
