H&R delivers another clone when you need it most. This M16A2 build is ready to outshoot everyone. The M16A2 is a lightweight, air-cooled, gas-operated, magazine-fed American classic. First adopted by the United States Marine Corps in 1983, it was soon adopted by all 4 branches of the military. You may still find a few M16A2 rifles floating around armories today at your local National Guard Armory. As always, these are made from the highest-quality US-made parts by their most experienced armorers.
