Red Dot MOA and Battery life

Postby jrh0516 on Wed Jun 09, 2010 8:22 pm

I’m looking to spend around a $100 on a red dot scope for my Ruger MKIII 22/45 and have a couple of newbie questions. Most red dots seem to specify 5 MOA at 100 yards. Isn’t this about 5 inch effective dot size at 100 yards? Does this mean about 2.5 inches at 50 yards? So for more accuracy should I look for a red dot with 3 MOA at 100 yards? Is a 3 MOA red dot going to be harder to see?

I’m shooting targets for mostly fun at an outdoor range and want to improve my off hand accuracy.

I was strongly considering the Sightmark SM13005 until I saw the battery life of 2 hours. Seems like I need to compare dot size, battery life, and warranty at this price point. Any other suggestions? Would Tasco’s fit this criteria?

Red dots can vary in dot size from around a 1 MOA dot an up. Many of the red dot sights in that $100 range do have a MOA dot size of 3-5. For most applications with a .22 either 3 or 5 MOA will work fine for you. I would encourage you to look at the Tasco Propoint 1x30mm. For around that $100.00 mark it is a top notch red dot that will work great for you on your 22/45. If you don't mind investing a little more you can get a truly excellent red dot sight in the Bushnell TRS-25. This 1x25 sight features a 3 MOA dot and can last 3000 hours on (1) CR2032 battery. This newer sight from Bushnell has received great reviews and is light enough to not affect your shooting style or grip you have on the 22/45. Bushnell and Tasco stand behind their products, but i do not foresee you having a problem with either.
