187th Airborne - Just something you might want to look into is replacing the barrel band with the band made for the use with the Buffington sight. It has a higher front profile which protects the sight ladder from damage when entering the carbine boot/saddle scabbard. Field trials quickly showed the ladders were getting caught on the lip of the boot and being folded backwards as the carbine was shoved into the boot. Companies like S&S, etc., may have one available.
