I put a reddot on my MKII 51/2
and it works great for me.I use the Bushnell Sportsman 1" with a MGW base from On Targetguns. I have some eye problems andthe reddots,I think are great for that. Sighting the target is fast.I just got one for my 10/22 Magnum andjust sighted it in yesterday.Hey our military uses them on some special OPs teams I hear.
