I've decided to scope my SOCOM 16 using an A.R.M.S. 18 mount. I want a 1-4 or a 1-6 30mm compact scope but there are so many out there. I'm looking at the Burris MTAC 1-4x24, the TAC30 1-4 and the Vortex Strike Eagle 1-6. Just wondering if anyone has used one of these. I can get the TAC30 with a Fastfire III for just over $400 and that's the way I'm leaning right now. J.B.
