AR15 Semi Auto 20" Finned HBAR Barrel Squad Gun.

This rifle was originally designed as a full auto squad gun. It is now a semi auto version. It is a one of a kind rifle with a premium Douglas XX air gauged 20" finned barrel with a M60 bi pod, carry handle and forward grip. The barrel was finned to reduce cooling under sustained fire. A3 flattop with an Elcan rubber armored Optic. It also has a 2 stage 4 lb. trigger for rapid fire. Extremely unique weapon. We manufactured about 5 of these barrels in the last 10 years and this is the last one.
