Very stable and sturdy - Magpul ACS Mil-Spec Carbine Stock

I would say that this stock has been the most comfortable I have used. And the storage compartments are nice touch! The lever mechanic is great for positioning it at your adjusted length. And the friction lock is a wonderful feature. It really gives your rifle a "solid" feel. However it is a bit difficult to install the stock. They provide a dummy bullet (they used to provide 3) and you use this round to pull up on a little hole in the switch. But it is impossible to do without getting the exact perfect angle. I ended up breaking the tip off the dummy bullet as well as 2 allen keys I tried forcing into the hole. What should have been simple turned infuriating. But after installed and my first couple trips to the range I am blown away by the difference it makes.
