FMJ 556 X45

Guns * Gear * Survival * The Right To Bear Arms
I swapped my MATECH buis for the Knights Armament 300m buis. This is the smallest buis on the market, it only takes up 1 slot on the picatinny rail allowing me to mount my TA31F ACOG in the T2 slot for proper eye relief with the stock extended.
Protip: if you see a KAC 300M sight with a hex screw instead of a slotted screw it is stolen from the USMC.
