my rifle is a Colt/Springfield that was tuned for N-SSA shooting, IE: tall front sight, spare tuned locks with spare internal parts, etc..
I have a couple sight blanks, and a friend or two left in the machine room where I retired from (Gen. Supv.). Making a new one isn't a problem. :wink:
And, after shooting for a few years ya' kinda' get an idea for where the sights need to go...
