This. (Or of course a red dot). The $175 Weaver 1-3x20 is 9.2 inches long, and is one of the very few scopes that's short enough to really be suitable for an SU-16. It's not quite perfect, a little shorter would be better, so I imagine the 8.8" long Nightforce NSX 1-4x24 might be even better, but it's over $1000. At 8" long, the Leupold FX-II 2.5x20 should fit very well, if you're happy with fixed power.I'm running a basic Weaver K series 1-3x. It's short enough that you can field strip without removing the scope.
