    A blast!

    This Kit was my first introduction to the Ar-15 world. Was a blast milling out the lower and putting everything together. The milling took me about two hours, but that is because I was in no rush. On the assembly the hardest part was installing the trigger, mainly trying to align the pin with holes, in order to do that i had to compress the disconnector but couldn't seem to get enough force down on the disconnector spring to align the holes, so found a nail the same size as the pin hole cut 1/4 in of the nail off, compressed the disconnector with vise while outside the lower put make shift pin in hole, dropped it in the lower then was able to align and hammer pin thru, pushing out make shift pin in the process. Everything else was smooth sailing. I definitely recommend this kit, and this company for excellent customer service.

    Literally EVERYTHING you need

    I am new to this and this kit made it so simple. I didn't have to think about what all I needed to complete the build because this kit had it all. It made the whole process fast and easy! Now I'm addicted and I NEED to build more!


    Worth the buy

    Very good kit, came with everything you need. I knocked it out last night after work in about an hour and a half. Only thing I had a problem with was the safety selector switch fit too tight and the detent pin for the safety selector wouldn't go all the way down. A few seconds of clean up with 2000 grit sandpaper took care of that no problem. I was plesently surprised by the gun case I was expecting a cheap plastic case but it's well made and sturdy. Overall it is definitely worth the buy.
