B K on an A2 Upper receiver at the sight. MMS on an A3 Upper receiver. SS 556 on a barrel just ahead of front sight base. 556 on a barrel just ahead of front sight base. Triangle over a Block M on an A2 upper receiver. (also a 3 or a B) An L on the base of a A2 peep, where the 0-2 usually is. Thanks a lot, everyone!! |

BK likely Bushmaster. Barrels with 556 or 556 SS are likely Olympic. Triangle over a block "M" - could this be the splintered "A" of Anchor Harvey?? - could be Olympic, Bushmaster (and others I believe) - not sure of the "3" or "B" if it is an Anchor Harvey - have seen this on carry handles "A3" or "AB". L on sight aperture - older designation for long range peep???. Never saw or heard of an "MMS" A3 receiver, can't even guess at that one. More help may be on the way from others. |
| I believe the A3 MMS upper may be Mega Machine Shop Inc. (WA). www.carricozarmory.com/megamachineshopinformation.htm |
