Hi, I’m thinking about building AR9 pistol with Glock magazine. Reading this thread, looks like there is no established option? Aero did not release their pc lowers. Other suggestions were FM-9 and Spartan, both not without flaws as I understand?
Did anybody build reliable AR9? I’d like to buy a stripped lower and start from it, but cannot choose a lower that most people like. Especially today, when everything is out of stock. At this moment there is only FM9 Build Kit available for $300+
I would strongly recommend the CMMG radial delayed blowback system. Much softer shooting than the direct blowback guns.
