Tried others but this stock rocks

Not trying to be a fanboy, so I tried other brands but found myself coming back to Magpul. For the price, the stock is solid and my particular stock had almost zero wiggle. I went with the ODG stock for this build and I am loving it.

So glad I found AT3 and they had this stock in their inventory. The shipping was fast and the price was right. FUOP!!!

Awesome service

I received the wrong product and called up AT3 and they had the right part to me a couple days later. There is no company with better/faster service right now and I have ordered from a lot of other companies. Wouldn't hesitate to order again! Keep up the good work
