Vortex Strikefire II cowitness question.
- Thread starter McHoss
- Start date
Because I haven’t fired it. I only just mounted it. It’s my first AR optic. Looking through the sights it seems to be lower 1/3 but everything I read seems to point to absolute with this height mount.
Is it possible the red dot is way out of whack and needs a major elevation change?
I’m new to the AR game so kinda clueless in this matter.
Thanks for the reply. It’s nice that yours wasn’t sarcastic.
When first mounted were they dialed in fairly close or pretty far out?
Absolutely, I get that. But from what I’ve read they come zeroed to 50 yds and are normally fairly close.
For me to get an absolute cowitness will require a lot of elevation adjustment. And it seems like I’d have to be quite low with my cheek weld.
My uncertainty comes from having added a new MBUS and red dot at the same time. So neither is zeroed. I was using a detachable carry handle sight prior.
No sight comes zero'd for any rifle, you can't just put it on and think it will be on at 50 yards.
They typically come with the turrets in the 50% travel position but even that is just a maybe. You'll have to go out and shoot your rifle to zero the sight.
Why do you want to look through two sights at once?
Just use your red dot and use your BUIS as they are intended which is Back Up Iron Sights. All you're doing is cluttering up your sight picture for no gain in any aspect.
The only benefit to having a set of BUIS on your rifle is when you install a co-witness height dot sight you can zero your sight in your basement without firing a shot.
Because if you have a fixed front sight, absolute puts the dot around your front sight unless you raise your head slightly. It's a cluttered sight picture. Lower 1/3 is nice for this. With folding buis I prefer absolute so if I ever need the buis I have the best FOV through the optic, but no buis in my fov when they're flipped down. P.s. it doesn't matter which cowitness height you have for zero'ing. Whether its absolute or lower 1/3 your buis and rds zero's operate exclusive from each other. Even with a lower 1/3 if you look through your rear aperture at your front sight, your dot will appear in your sight picture in relation to your irons zero. So if your optic and buis have the same zero then sighting down your buis with proper sight picture, your dot will be on your front sight post. Raise your head above your rear sight and the dot will follow your head up through your fov. Give it a try, flip your buis up and sight through them, then adjust your rds until the dot is at top dead center of your front sight with a proper sight picture. Now raise your head and watch the dot appear to move up. Thanks to the genius of rds, head position does not change where the dot is transposed on the target. You can try this with the rifle set up pointed at a poi and notice the dot will stay where the rifle is pointed as you transition from buis to rds, so long as you don't move the rifle.
Excellent explanation. Thank you, it makes more sense to me now. I was wondering about the dot moving when my head did etc.
Clearly I’m new to the AR and RDS world. I figured I’d up the numbers and get in before the crack down. Now I’m kinda hooked and have started to add some personal touches to the rifle.
