Same here. Designed around Glock magazinesMy FM Products AR-9 uses glock mags. Many AR-9's doo.
It works great. I have one that uses Glock mags.There is a new (2019) magazine adapter block by Stern Defense that fits easily (slides in like a magazine) into a standard AR15 lower. They offer a couple of models for either Glock magazines or S&W/Sig mags. My shooting partner uses this in his AR15 to convert over to run PCC competition. I have watched him shooting 5.56 and swap out his upper to a 9mm and drop the mag block in... 2 minutes later he is shooting an AR9. I am surprised by how easy it is to install and reliable.
If you don't want to buy a dedicated pistol lower or want a simple solution to building an AR9 on an AR15 lower then this is something worth considering.

I was disappointed in the AR9 platform. The ones I've seen use a blowback design which produces recoil as great as an AR firing .223. I was expecting it to be more like a .22 and learned I could not shoot it any quicker than I could shoot a standard AR in competition.
Tuning of load, springs, and overall mass (BCG and Buffer) is required for best results. My AR9 SBR has far less recoil than any of my 223s and I can shoot it faster. Never going to be like a .22LR though.I was disappointed in the AR9 platform. The ones I've seen use a blowback design which produces recoil as great as an AR firing .223.
