AR-based and other such pistols have never been more popular, and as pistol-caliber carbines have also become more mainstream, it's no wonder the two haven't been put together sooner. Of course, there have been variants around for quite some time, but it seems like 2020 has seen a dramatic increase in this relatively new style of handgun. One thing's for certain: Stylewise, we've sure come a long way from the Bushmaster Arm Pistol.
