I have decided to go with this system on an M4. In the past I have bought and sold many sighting systems for AR's, and taken hits, but I think that this setup can be used in many areas, and I will need help sighting it in.
Everything is on a Colt M4A3, 14.5in. barrel, with 1/7 twist.
At what distance should I sight in the :
ACOG TA01NSN ( mounted to A.R.M.S. 19s )
Optima sight ( mounted to the top of the ACOG for CQB )
A.R.M.S. #40 ( mounted directly to Colt rail )
Thanks,
KZ
