Very nice kit, everything you need to complete the build. What I loved the most was reach piece was in a separate labeled bag. Made knowing what goes where very easy.

Great kit. I love how every step in the assembly instructions pdf has a corresponding baggie of parts. The cost of entry to getting yourself a semi-autonhas never been easier than this build + this kit.
Don’t forget to weigh your metal parts, and double-check whether you get to the magic 3.7oz or 105g!
