The SOCOM M4 Block II barrel: Magic? ...or tragic? (Facts and rumors - M4 SOCOM barrel)

It investigates popular civilian claims about its sub-MOA capabilities, ability to substitute machine gun fire, and improved accuracy when heated. The host questions whether these benefits are fact or rumor, noting the lack of military documentation and considering if its primary purpose was simply to mount an M203 grenade launcher. The video also acknowledges contributions from Jeff G at Modern Tactical Shooting and Ian at Forgotten Weapons, and directs viewers to support the channel via Patreon and Slate Black Industries.
