A3 Stock
Bought this to replace the A2 stock on an HK94, was worried it would be to dark but it if matched perfectly… stock came a few days after ordering, quick turn around as always from AU

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

Hk Mp5/ Sp5 F stock
Product arrived quickly and was well packaged. Stock itself was in factory Hk wrap. 100% as new no complaints. This is the 3 position; open, closed with one shorter setting in between. Buy with confidence. Thanks Arms Unlimited!

Genuine H&K
Fit and finish is perfect. Glad I went with a genuine H&K stock

A3 F type stock
A massive improvement over the legacy A3 retractable stock. Better length of pull, and cheek weld. The fitment is also infinitely superior to the legacy deisgn.
