[QUOTE="trbii, post: 203973, member: 2449"] Speaking of 14.5" barrels, do you suppose our troops are ever able to engage targets out to 300 meters or beyond, successfully? I've read 100 fps loss of muzzle velocity for every inch of barrel less than 20". My reloading manuals usually say loads tested with 20" HB COLT AR-15. So figure 500-600 fps MV loss coming out of the M-4 carbine? Christ help our troops, a short range varmint cartridge made even slower, weaker? Maybe good enough for making "good islamofascists".
