The Rock River Lower Parts Kit with Single Stage Trigger is a great value. This complete kit is good for immediate installation or as a spare parts kit. I ordered it from Primary Arms who shipped it immediately for less than $5!

Excellent Quality

by -

Building a complete AR, ordered this part kit and was amazed. The trigger is super smooth for a mil-spec trigger. Everything was excellent and high quality. I would recommend this parts kit to anyone looking to build a high quality build. You can't go wrong with Primary Arms. Their customer service and fast shipping is exceptional.
