    Stock arrived fast and exactly as described. Locks up correctly & tight with no wobble. The fit is perfect as it should be, This stock and that gun go together like peas and carrots. Its also marked H&K which gives it a nice genuine accent. IMO its the ONLY stock that belongs & looks correct on this model H&K to keep the traditional authentic look. Its worth the extra $ and wait of registering it as an SBR as this stock once again compliments this weapon and makes it COMPLETE . These are too nice of guns to put that insulting goofey looking brace on when you have this option. Go for it, You’ll be glad you did. Thanks Arms Unlimited!

    Was worried about ordering the stock. But it came sealed in the bag inside the box and is a legit HK marked stock.

    I got a shipping notification literally minutes after placing my order. I thought it had to be an error. Nope. They're just that fast!
