Sure - not a problem. Does the webiste here provide a link or do you need my e-mail address?

Can't seem to get the pics posted of Bushmaster M4 bolt assembly for you, can I email to you? I will say that I noticed a difference from the Bushmaster M4 Full auto's and the semi autos owned by several Officers. The full auto Bushys are staked much the same as my Colt 6920. I can email the pics if you want.
