vortex sparc VS primary arms micro

[erwos]

1/3 co-witness means your front and rear sight picture is in the lower 1/3 of the optic. This is as opposed to absolute co-witness, which puts it dead center (ie, the dot should be on your front post when looking through the rear sight).

1/3 co-witness is generally used when you've got a fixed front sight. Absolute co-witness is better when you've got folding front and rear sights. It's a somewhat weird choice to go with the emitter at 6-o-clock when you're going for 1/3 co-witness, albeit I think it's cheaper to manufacture.

I'd suggest taking receipt, mounting it up, and if it doesn't work out, return it. They'll be cool. I have a couple of PA dots that I use on rifles that I haven't found the cash to buy proper higher-end optics for, and with one exception that is no longer made, I've been extremely happy with them.

thank you everyone for the input... my question is this (don't make fun) is 1/3 cowitness refer to using rear back up sight with the optic with the front sight? customer service is huge for me so if the cheaper micro is not a big deal... I may just get both. ask the gf for the sparc for Christmas

Here...This video explains it well.

i have a good lower 1/3 wittiness with my PA micro on a American Defense QD riser with magpul buis. Primary arms is good to go i love my micro

For a budget micro I'd opt for the PA. Owned two as stop gap solutions. Neither failed. Only sold when the budget allowed for better optics. Never liked the Sparc due to the crazy looking bulky controls on the side.

Sent from my piece of s**t phone using Tapatalk2 (which can be equally unreliable when coupled with a junk phone)

Received mine and mounted it up. Testing against folding Troy and Magpul MBUS sights; yes the emitter at the bottom obscures some of the sight picture, but not nearly enough for me to upset about the $60 I spent.

I just received two of them today, the led emitter covers the 6oclock position where the tip of your front site would be. 1/3 co-witness is pretty much out of the question.

Sucks to find out the hard way. I hope they work out for you otherwise.

Don't sweat it too much. The real PA micro has the LED circuit visible in the front glass at about 5 o'clock, where it obstructs the lower one-third view on the right side when looking through the irons. So almost as bad. Supposedly, the new Seekins mount helps to fix that by slightly lowering the RDS, hence it slightly raises the view of the irons.

I bought the more expensive primary arms micro and it is lower 1/3rd capable I love the sight on my AR

I mounted on a flattop rail with larue flip up sights, you are able to see the tip and sides of the front site and the rest is covered by the blob of the led, it'll get the job done and if it become a issue it only takes a second to pop the sight off.

Does anybody know if these can handle the recoil of a saiga 12

That's the problem. Nobody knows. It's not a PA micro dot. It's a one-time buy by Primary Arms with no track record and a different warranty.
