480: War on Brains
AR-15 Mechanics, Upper Receivers and Gas Piston Systems
A listener provides technical details on the H&K upper receiver for the M16/M4 platform, which utilizes a piston system rather than direct gas blowback. This modification is intended to prevent the weapon from fouling and jamming over time. The hosts link this technical update back to their earlier discussion on the influx of new gun owners.
