AR built
Review by Steve

I put them in my first AR built, everything fit perfectly. Used with a Geissele 2-stage trigger. I would recommend these parts

Review by Matthew

If you are debating which lpk to get save yourself the irritation and get this one. It's quality from start to finish. I've done the research and the parts are sourced through a quality supplier.
