In this instance it is a custom M4 built for Airport scenarios. Ranged scope/probably grips for ranged shooting and bullets designed to pierce plane windows.

Not sure if it has full auto but no one shoots carbines like that spray and pray style anyways. "Patrol" rifle just makes it sound like less of an oppressive death stick, as the whole assault rifle thing is just a shitty use of an adjective to sway opinions. For example AR-15 is a specific brand model like mountain dew code red not assault rifle 15 and half the articles that mention them are actually talking about different guns.

Education creates safer gun users and will lead to laws that actually create safer places.

Banning bump stocks then not getting cops in trouble who leave their guns unlocked accomplishes nothing.
