PA is a just having to come to grips with the new reality… AR15’s are the most popular rifle for people under 50yo. I bet if you did a survey of 18yo - 50yo the common answer would be that essential firearms are AR15, Glock, and Ruger 10-22 … the only arsenal you need to survive the apocalypse
Arguably since the Gulf War, but at least for the last 24 years (post 9/11) the M16/AR15 may be the only rifle to be used, fired and then personally owned by a large number of adults. For everyone else in this age range,who didn’t serve in military, the M16/AR15 has been their “virtual firearm” used in every video game that they’ve played. It makes sense that ithis is the firearm they want to hunt with.
MagPul could easily pump out 3-round mags or simple use their existing 5-round mags with either a spacer or modified follower that limits internal capacity to only 3 rounds. Polymer magazines are easy to make and therefore cheap.
