Sorry for my ignorance. I am just starting looking at all those hi-tech sight and you are using a lot of acronyms that means not much to me. head.gifIf somebody could help me understand this hi-tech language I will really appreciate.hanks,Clovis

Not quite an answer to BAC, but some other sight related acronyms:

•ACOG: Advanced Combat Optics Gunsight (does this refer to any scopes other than those made by Trijicon?)

•TA01 and TA## etc. are models of Trijicon ACOGs.

•ARMS or A.R.M.S #__ are mounts of varying sorts made by Atlantic Research Marketing Systems.  For example, the ARMS #40 is a popular BUIS.

•BUIS: Back Up Iron Sight (just the rear sight minus the carry handle)

Now we wait for the actual scope users who would know a few more to reply...
