    Factory HK K Stock

    Posted by Unknown on 27th Jun 2018

    Excellent quality stock with positive lock up. Minor play in the fitment to the receiver develops over time. The best folding K stock I've found thus far. I prefer this design to the touted B&T style stock. ArmsUnlimed by far has this best price on this part I've seen anywhere. Brownells comes in second if Arms is out of stock.

    Just what I was looking for.

    I have yet to go to Arms Unlimited, and not find what I was looking for, when it comes to some specialized items. And at a great price, for a PDW build (reg. SBR)
