I'm putting together a 300 blackout pistol and wanting a 1-4 or 1-6 optic. I'm looking at the Burris Mtac, Vortex Strike Eagle, and Leupold Patrol right now. This is going to primarily be a truck gun and may shoot a few hogs with it and that's about it, so I'm not going to dump a lot of money in it. Anybody got any suggestions for around $400 or less?
