I'm a big fan of the reflex type red dot sights like vortex venom/Nikon spur over the tube type. (highly recommend the nikon, I have it on a 12g shotgun right now and its held up just fine)
If you're after the tube ones, the trs will meet your needs but i'd also look at the vortex Sparc AR, Nikon makes one too in the 200ish range but its never available when im looking.
Best thing about all the red dots mentioned is they aren't limited to a rim-fire, having an option to put it on something else helps justify the cost.
I'd avoid one with a massive 6 or 8 moa dot for a rifle, Usually try to find 2 or 3. that may just be personal preference though.
