Good morning,

I'm looking to build a retro XM177 / CAR 15 (with compliant barrel/brake). How do you pin the stock to keep it from collapsing and be NJ compliant?

 

Thanks

Since there are NO specific guidelines about pinning a stock, one or two blind role pins through the stock and the lower buffer tube extension should suffice. Additionally the manufacturers inactivate the adjustment lever by tapping the adjustment hole and inserting an allen head cap screw which may or may not be necessary.

 

Just make sure it is not clapsible.

If you are overly paranoid an alternative meathod is to make a drilled hole between the stock and the buffer where the adjustments go and you can rivet the stock to pin it. You need a rivet gun for this and a rivet that is long enough. Or you can do what was mentioned above with the roll pin.

IMO if the stock doesn't collapse, you have satisfied NJ law. However you manage to do this is up to you.

I am sure your opinion will be of great comfort when Bubba is making him his own.

 

Make sure the pin does not go all the way through so it can not be pushed out the other side thus making it easily convertible back to a collapsable.

There are problably many different ways to make a stock not be able to collapse any longer. My interpretation is that the spirit of the law is looking for a stock that will not be able to be adjusted with your bare hands, or novel tools very easily. If you have to start drilling/cutting/breaking things loose in order to make it adjustable again, then you did it right.

 

My favorite way is a pin or two through the stock into the buffer tube adjustment ramp. I then epoxy both ends if I drilled through, or the one end if I was able to make it a blind pin.

is there something in the law that draws you to feel that is needed.. I have read the law up and down on many occasions.. I am no expert but there appears to be the following in NJ..

 

there is the LAW

and

there is opinion based interpretation of the law

 

when you follow anything other than the law it may make you feel better.. it may make you feel more safe.. but unless the law dictates something about pinning stocks.. the manner in which it must happen.. then you are not really making yourself any safer? any less likely to be prosecuted..

I tend to agree with j0n.. the stock collapses or it does not.. if it does not.. then it is legal..
