    To make your rifle stock compliant in CA. I like the fact that this product gives you a better option than drilling a hole and pinning your stock. You can’t go wrong with the price either.

    Before you cut the strip, figure out which hole on the buffer tube suits you best. Then cut to expose that hole.

    Strike Industries AR stock stop is one of the easiest and quickest way to convert your collapsible stock to be in compliance with a featureless build. It's simple to install instructions are straightforward it can be configured to fit a 6 position collapsible stock or a 7 position collapsible stock. Once it's installed into the buffer tube slots for the collapsible stock. It fits extremely snug so it falling out isn't an issue. Purchasing it at Wing Tactical you can't go wrong take a look at the other products they have here too. I don't get anything for this review. I just want to give you heads up for a those who are looking for a quick and easy solution so you're not having to get rid of your collapsible stock.

  • Best solution for a fixed stock.

    Posted by V. M. Avila on 28th Jun 2018

    The was perfect for my application. The second to the last hole is my preferred option, but this could easily be marked by the manufacturer to be used in the other length of pull positions. Also, easily reversible is needed.

  • Good to go

    Fixed my Magpul stock, just as advertised. Would have liked more position options for length of pull. But, overall, very happy with this product.
