Ryan here: I really like the Burris MTAC. To my best memory what pushed me to the MTAC over the Vortex was that I liked the reticle better and the Burris MTAC had a good reputation. I have the 1-4X model. I sold an ACOG to get it and finance some spare parts. I wanted a ‘do everything optic’ and a 1 power (or darn close as a lot are like 1.1 to 30 feet or something) scope that could be magnified for longer range work with an illuminated reticle. I shoot better at distance with a magnified optic, honestly I think everyone does. Also the big difference between red dot (or irons) and a magnified optic is that I can see well enough to make good decisions. Yes you can hit at 300-400+ yards with a red dot but you can’t really tell if that person is a threat or a friend coming to help. My experience with shooting the MTAC has been quite positive.
Pros: It holds zero and adjustments are consistent.
The circle and dot reticle is pretty cool. The circle will work for really fast up close stuff and the dot is sufficiently precise for my needs. Its illuminated reticle is nice.
It is a rugged optic. John Mosby had one leave a vehicle onto pavement at freeway speed and all that happened is it jammed one of the adjustment knobs so you could not move it by hand. Short of an ACOG or say a Leupold HAMR I don’t think there is a more rugged optic out there and those are 3x plus the cost of the MTAC.
Cost- The Burris 1-4X MTAC is about $300 with mounting options for $60-200+. In this range the MTAC is pretty affordable and on par with an Aimpoint patrol or Eotech. All of these are within the range of a normal person given some planning.
Cons- Weight. Amazon says it weighs 1.1 points which seems about right.
Battery- They use the CR2032 which is kind of a special snowflake battery. I wish they used CR123 or AAs.
As to the Burris MTAC vs other offerings. I purchased my MTAC a few years ago,I was in Arizona so it would have been roughly 2013. At that time the moderate cost offerings from Burris, Vortex, Leupold, etc that had a 1 (or close) power bottom end topped out at 4 power. One power scopes with higher ends existed but not in my budget. The 1-6 and 1-8x offerings were in the high end Leupold, Vortex Razor and Night Force type with a cost range starting at a grand. I have been quite happy with the Burris MTAC 1-4x and think you would be too.
Fast forward to 2017. Things have changed. One power scopes with higher top end have matriculated into the moderate budget range of optics. The 1-6 and 1-8x Vortex Strike Eagle offerings look very appealing. Additionally the ability to put a quick switch lever on the scope to make rapid transitions is pretty cool. I really like that.
The Firearms Blog did a review of the 1-6X which seemed positive.
I am happy with the Burris 1-4x MTAC on my rifle but that doesn’t mean it is the best thing out there today in that same general (say $300-500 for the optic) price range. New stuff is available and in particular the Vortex offerings look very attractive.
I would have to look at the difference (beside the $100 or whatever cost) between the 1-6 and 1-8 power but unless there is a big downside a higher top end is better. A 1-8X scope from a good manufacturer that fits in an average guy budget without too much pain is pretty neat. At this current time with what is available now should I find myself in the market for another variable 1X scope I would look hard at the Vortex Strike Eagle 1-8X. I would spend the money to put it on a good mount.
For full disclosure I have no personal experience with the Vortex scopes in question so what I say is relying on a quick google search and Vortex generally having a good reputation.
Hope that helps,
