Well the first thing ,is that no other buffer tubes will fit the KJ, They use a two part buffer tube. That is their own design (a little weird I think).

If you really want to put that stock on,then you will have to make and mod something so you can do it,until more accessories start to hit the market.

I wanted a Magpul UBR on mine, everybody said it couldn't be done

so that was my incentive to find a way.I had to drill and tap one hole to hold the UBR on ,using the screw that came with the UBR.And I found a way to leave the inner brass buffer tube intact.

The full stock you are interested in could be done but would need a little more head scratching.lol It's about 3 inchs longer that the KJ inner buffer tube.Would need to fab a piece to extend the inner buffer tube in length and girth. Then the stock could be held on with the proper screw.The other problem is how the front of the stock would mate up with the receiver end plate,(part # 51) :banghead:

Do you know anyone that could make new buffer tubes? I would order a couple
