Overview of the Colt AR15A4 Semiautomatic fulllength rifle with carry handle. This is recent production. For accurate and detailed info on Colt rifles tune in to Chris @SmallArmsSolutions . This rifle is a soft shooter and reminds me of the days in the 1970s larping in the woods with buddies looking for VC with our toy M16s. There is a great video on using the drum for sighting at distance @Mrgunsngear channel.
