Compact - Great for AR9!

I purchased this for a dedicated AR9 build and it look and works great on my compact AR9 pistol build. Mil Spec pistol braces fit!

Strike Industries has quality products and this one is no exception. Only gotcha is it does not include the end plate or castle nut so if you are doing a new build make sure to buy those!

Uh, yes please...

Awesome sauce. I found I prefer my cheek as a third point of contact. This 5 inchish length is just right for how I run an AR pistol. Looks great, installs great, and the QD point on the rear is perfect for sling resistance when pushing out. Get it, or don't, I did, and love it. Cheers.
