    This was my first kit and I expected to wait awhile for shipping with all the covid-19 stuff happening. It still made it to me within a week. Was packaged good and nothing was missing or damaged. Everything went together very easy and fit an Anderson stripped lower perfect. They threw in a coozie and sticker also. Great prices and great prices, will definitely buy again.

    Awesome kit, great price. Even with the Rona happening I still received my kit within a week and all the parts were there and the rifle shoots awesome. 10/10 will continue buying kits from Durkin Tactical.

    Great build kit, this was my first build. I expected it to take awhile because of demand and Covid. I ordered on a Saturday and had a package by Monday afternoon, very fast shipping. All the parts were included in the kit, it all went together with a minimum of fuss. I will be buying from Durkin again for my next build.
