80 Percent Arms

Simply stated, 80% arms are the best. The communication, service, quality, and information are top notch. I’ve used the universal gen-3 jig for multiple AR-15 lower builds and the product makes it so easy to complete. Any mistakes are mine and not the jig. They’ve designed it to be as idiot proof as possible. Each time I use the jig it gets easier and faster. The lowers I’ve done the last few times are perfect. I just needed to get some practical hands-on experience to work through the kinks. If using the jig for your first build, get a practice lower if you can. Otherwise go slow and check that all bolts and and screws are locked in after every pass! Final nugget, make sure when drilling the hole for the trigger pins and the safety selector are perfectly perpendicular both horizontally AND vertically! Next phase will be the GST-9. I’ve got all 3 lower color - Black, FDE, and Patriot Brown. Can’t wait to dive in!

When in stock you ship very quickly. I've ordered many different lowers from you and have only one comment. The AR9 needs to have a standard mag release instead of the proprietary one that you use, or you need to offer things like Extended levers. Other than that you are my favorite 80% supplier.
