Jeb B.

I was really happy with the help I got from Crow Mountain Armory to build a California compliant AR-15. I spoke to David from Crow Mountain several times and he was happy to answer all my questions and there were a LOT. Together we decided that a “Fixed Magazine” build, meaning I can’t drop the magazine, would be the best option for me. David even took the time to actually educate me on a bunch of the silly California state laws. When David flew out to help me build it we had a great time and again David took the time to teach me how to build a really top of the line AR-15. He was patient and instead of just doing all the work himself and getting it done in 10 minutes he took over an hour and helped me build it myself. I’m really happy about this because now I know I can service it myself. The parts he suggested I buy feel very premium and I was happy I didn’t skimp out. The next day we went to my local range and David taught me how to zero the iron sights and red dot. He was really patient with every aspect of the preplanning, build and at the range. I would highly recommend Crow Mountain Armory to anyone looking to buy a California Compliant AR-15. Even after our transaction was over David advised me on what sling and light to get. I’m super happy with my purchase and because of that my dad decided to have CMA build him a rifle. Thanks David and Crow Mountain Armory!!! -Jeb B. Southern California
