    This stock is very sturdy. The 3 adjustment positions are very easy to adjust. Installation is simple as well. Adjusting can be a little stiff but after two or three adjustments it’s smooth.

    Best price I have ever seen on genuine HK 3 position A3F stock. I received what they advertised in new condition. This is an excellent buy and a great company.

    Quick shipping, good product. Seems like the real deal - it’s more substantial than I thought it would be. Absolutely no wiggle.
