but performance is decreased exponentially the shorter the barrel is.
i remember when I bought my AR they didn't have many choices. i could get the full length barrel, or a 16.
the 16 vs. full 20 already has a 10% reduction in velocity and accuracy. basically -10% overall less performance.
shorter barrels also have cycling problems (or more prone to).
my question is, with the velocity loss, and the shitty .223 FMJ rounds we have access to, that means the bullets wont tumble or shatter when they hit the target unless we buy .223 hollow points.
if a .223 bullet doesn't tumble or shatter when it enters the target, then you're basically just making a tiny hole in your target and your weapon is ineffective.
i mean... unless you guys just wanna blow off rounds at the range. but i got an AR-15 for a reason lol. i want the full functionality and capability of the killer round.
you guys with the ultra short barrels, do you notice any problems hitting targets out at 250-350m+?
also where and which type of .223 rounds do you guys use?
