Bought the Complete Colt A2 upper as a conversion kit, circa 1998.
Sold the Pre-ban Sporter it was mounted on up north, some years back, Minus A2 Stock.
A friend, who is a Certified Colt Armorer, put together a new lower for me, using all Colt parts.
Scope Mount is A.R.M.S. N° 2.
Scope Tasco 3-9x40 Rubber Armoured (Colt Delta Style).
Please excuse poor pics, daylight was fading. Perhaps more later.
