Definitely recommended

Works great, excellent price. 01/03/2018

I needed one of these kits to finish up assembling an ar15 lower. The fit in finish was perfect for my stripped Ruger lower and I had no problems with the installation and functionality. The Magpul Mil-spec stock I already had fit perfectly with no extra play or slop. I would buy another one of these kits.
