*Installation must done by your local certify gunsmith*
the Hammer with "J" spring
Excellent quality and great price for the quality
I did not yet install the parts kit on any AR lowers. But if you ask me I’m sure the quality is all the same…. But what I am the most impressed about with this company was the major super fast shipping I live in PA I placed my ordered Wednesday night and received my shipment Saturday afternoon..
Thanks again for the timely delivery and quality parts.
