Duel of the Carbines: M1 Carbine vs. M4

[Sunray]

"...M1 has a less threatening image than..." And is still considered to be evil in some places. Our idiot government declared 'em evil in 1978 because they thought the barrel was too short. Bikers were using 'em for their nefarious and illegal business ventures.
"...not accurate past about 200..." That's more about the particular Carbine and the shooter than anything else. The M1 Carbine was considered to be a 300 yard weapon by the U.S. military. And the .223 is still a varmint cartridge that was not designed as a battle cartridge.
