Garand Thumb checks out the FN SCAR-L if it is up there with the best of AR-15s... "The SCAR-L / SCAR 16S in 5.56 is such an interesting weapon. It came at a time when the M-4's reputation was dubious amongst many in the Military community. Although the SCAR-L ultimately fell out of usage with the Military it is still none the less in usage amongst certain units in the US Military such as the 75th Ranger Regiment."
