What do you want to do with this gun?
Build one, it will save money and give you more pride in "your" gun.
How about the original M16/AR15...
Colt.
Just priced an AR-15A2 Government Model carbine at $1,190...I know where that income tax return is going...
without trying to be a smart ass - shoot it!
just a gun to have and burn up some ammo at the range
The original is Armalite.
