A few questions about rear irises
Posted: Mon May 18, 2015 12:29 pm
I've shot NRA Highpower Service rifle for quite a while, which uses a simpler aperture rear sight and front post. So learning the smallbore game, is jumping into the deep end regarding equipment and complexity. Looking at the available rear iris offerings, I'm seeing the following options available:
1) Adjustable iris size - I understand this one, and it seems to be pretty much a necessity once you get serious about shooting.
2) Color filters - I understand that the different colors can help increase contrast, etc. Is this something that really only comes into play when you're shooting from 10.0-10.9's consistently or is this something that would be a good thing for even a newer shooter?
3) Polarization - Again designed to help with the sight picture by allowing in different levels of light. Is it the same as above in terms of utility?
4) Magnification - Is this basically a simple optical magnifier? What exactly is the purpose of this? I get using a magnifier to be able to see an aimpoint (say shooting at a 1" diamond at 300 yards), but what exactly does it do for the shooter when you can already see the bull and the sights? If it's more of an optical clarifier that means I could shoot without glasses, that makes much more sense.
I'm currently leaning towards just a simple adjustable iris, as at the moment I don't think I'm dropping and X's due to a lack of color filters or polarization. Honestly a new match sling (still using my web service rifle sling) and a SB specific jacket would probably be worth more X's. If magnification is a replacement for prescription shooting glasses, I will definitely spend for that, as my current regular glasses do not work well for shooting SB.
Thanks in advance,
