Butters149 Posted July 10, 2020 Share Posted July 10, 2020 Hi I was wondering if there was a kit or a diy on how to pin the m4 c-stock? I got one coming and I live in California so that’s why I need to pin it some how. Quote Link to comment Share on other sites More sharing options...
Milspec Posted July 10, 2020 Share Posted July 10, 2020 Somebody put a link in a different thread a few days ago. I think some guy on Calguns sells a pretty nice kit. Quote Link to comment Share on other sites More sharing options...

Vertigofirearms Posted July 11, 2020 Share Posted July 11, 2020 If you go that route, you can buy an extra button in the event you mess up the hole. https://www.midwestgunworks.com/page/mgwi/prod/70093 Quote Link to comment Share on other sites More sharing options...

Vertigofirearms Posted July 11, 2020 Share Posted July 11, 2020 Pretty much you take the stock apart and drop a pin in. You can reassemble or modify the button to be easier to limit. https://www.calguns.net/calgunforum/showthread.php?t=1507997 Another option: Quote Link to comment Share on other sites More sharing options...

Vertigofirearms Posted July 11, 2020 Share Posted July 11, 2020 Oh you are correct. If you want it to be easily removable you will have to cut some metal. You could also install the M1014 single position tube. Quote Link to comment Share on other sites More sharing options...
StrangerDanger Posted July 11, 2020 Share Posted July 11, 2020 I’d get a pin that is smaller diameter than the button spring. Then cut it to length so the button cannot be depressed with the pin inside the spring. I’d leave just a small amount of play so you can depress the button slightly when tapping the retaining pin in place. This would be a lot easier than drilling a hole thru that steel button, then tapping it for a screw. The only way to get the hole drilled properly would be to indicate it in a lathe. Preferably on a 4 jaw Chuck. Trying to punch out the hole with a drill press is likely going to be off. Quote Link to comment Share on other sites More sharing options...
Butters149 Posted July 11, 2020 Author Share Posted July 11, 2020 Got it I have an idea. Is the button easy to remove from the stock? Quote Link to comment Share on other sites More sharing options...
Vertigofirearms Posted July 11, 2020 Share Posted July 11, 2020 Not easy to remove. Buy the best roll pin punch you can afford. Quote Link to comment Share on other sites More sharing options...
StrangerDanger Posted July 11, 2020 Share Posted July 11, 2020 I knock mine most of the way out with a Starrett punch while pressing the button in slightly. The punch isn’t quite long enough to knock it all the way out. So I then use a set of transfer punches. The larger diameter Starrett punches will last a lifetime. The smaller ones are consider consumable and are easily destroyed. Particularly 3/32 and 1/8 punches. Quote Link to comment Share on other sites More sharing options...
