Have a 20 year old AR upper with fa. It has a plum tint color to it an the only markings on the upper receiver are under the right windage adjustment. The letters are L M. One gunsmith thought it might be an early Bushmaster. Anyone have any idea to who the manufacturer might be? thank, Vikingok. |
Pics of it showing the marking would help a lot; you can also visit this LINK for visual info on your upper, including forgemarks. Hope that helps. |
