great product. fast shipping!

I ordered a magpul stock in ODG and a buffer tube from AT3 tactical. I couldn't be happier with my experience. Everything was as described and shipping was super fast. Thank you AT3 tactical!

Not just a pretty face.

I had the basic butt stock. A little too snaggy and no sling options. I up graded and got the dark earth to match my grip. Not only does it look good but sling options, absolutely no rattle and very comfortable on the shoulder.

Thank you for your feedback! We're glad to know that you're happy with your upgraded Magpul MOE SL-K Stock - Mil-Spec - AR15/M4 - MAG626.
