[ARCHIVED THREAD] - Question on Bushmaster A2 upper

Posted: 5/7/2005 5:11:33 PM EDT

I have an A-2 Bushmaster LE marked 20". The upper is marked with a "B" and an "M" with an upside down triangle over the notch of the "M". I searched for some forging mark posts, but came up dry. I was curious where this upper came from or if it was actually Bushmaster's work.
Any help always appreciated.

I guess the pics didn't help.
Maybe I should post pics of nuts and bolts; something a tool can relate to.

Yeah, that's Bushmaster's work. They put out a batch of A2 uppers (last year?) that had a different radius behind the rear sight (yellow line). It was visible in Bushmaster's printed catalog as well as some other on-line pics.

Thank you Sir. I appreciate the info. I had not noticed the difference in the profile until you pointed it out just now.
