OK, I have a similar question for Jarrod on the BM uppers.
I was just reading the info on http://www.biggerhammer.net/ar15/uppers.
I bought a BM Pre Ban M4A2 upper 04/18/02 direct from BM.
I find on this reference page that my M4 upper has none
of the BM stampings, FK,FS,BK,DK,EK,FK,AF,CW,AA or FS, indicating that it was mfg. by BM.
It has an A with a dot over it breaking the tip. IF, this is considered a splintered A, the damn upper was mfg. by Olympic Arms, not BM as I thought when I bought it.
Mt son has a BM HBAR with the same upper marking. Is his NOT a BM upper also?
Before I buy another BM product I would like to know that I am getting what I'm paying for, a Bushmaster.
I would really appreciate an explanation on this.
