"PDW stock"

Over all this is a nice stock. I bought it to build a HK416 clone. At first I was having problems collapsing and re-extending the stock (It would stick or require excessive force to open and close). It actually was an easy fix. If anyone has the same problem remove the entire butt and guide rod and fine tune the slide holes with a file and it will be perfect. I definitely recommend this for a cool looking AR build.


"Awesome Stock!"

Ordered it on a Friday and got it Monday with standard shipping, so kudos to these guys for shipping it so quickly. Very solid construction. Finish is very nice as well. 5" exactly from the receiver to the end of the buttpad when collapsed. The buffer spring is noticeably stiffer than the original, however. I also had to shave a little off the buffer tube inside the receiver because the upper assembly was hitting the tube and not fully closing. No big deal though. Overall, extremely pleased with... More details

This is the best looking and most versatile AR PDW stock on the market I just ran 500 rounds through a brand new carbine build without a hiccup. Installation was easy and the operation is smooth. Absolutely love the look of the rifle.
