Trijicon MRO

[The Hobbit]

Been watching classifieds waiting on a chance to,snag an MRO at a price I like. My question is what is the deal with the serial numbers? People seem to want a post 89k serial number optic. Is there a major quality difference between the pre and post 89k units?

The newer ones supposedly have less of a bluer tint and a true 1x magnification whereas the originals provided a very slight 1.05x magnification which can mess with you when shooting both eyes open. I have 3 pre 89k serials and they are all just fine to me. I guess if you can get a smoking deal, don*t worry about the serial #. It is a fantastic red dot regardless of the generation.

Anyone running one on a AR pistol? I'm thinking of getting one for a 10.5 5.56.

I don't think I'm going to put BUS on it so I want something good that will hold it's zero.

My only concern is that it will be a bit big and bulky. Any other recommendations for something decent, that's under $500 are welcome.

It's a great optic with great glass, my other recommendation would be the Holosun 515 GM it's bomb proof. If you want to stay assembled in America Sig's version of the Holosun 515 GM which is most likely imported parts and assembled here in America is the Romeo 4T which can be found around the $500.00 mark give or take a few bucks. I have used the MRO many times and it's really great with excellent FOV in that big lens. I personally own the 515 GM and I really really like it since it's packed with a ton of features in a upgraded housing, and can really be put to the test. I have no experience with the Romeo 4T, I know they are used by some federal LE and have seen them tested on the net with great results. I have other Sig Options like the Romeo 5, I have several of them and they are the best budget dot on the market especially when they were $99.00, but even at $130-$150.00 I would still rank them the same so I would feel confident owning a 4T.

I also have 3 pre 89K and they're just fine to me. I suspect the serial # thing is a little overblown. When I spoke to Trijicon, I think they believe that as well but as they say, "the customer is always right."

My main concern with the MRO is that there's some testing out there that seems to suggest that it has a lot more parallax error than other red dots.

I cannot answer that, I am sure justin can since he has more experiance.

InRange Tv is slowly testing all the American made red dot optics and the Romeo 4T is the 4rd or 4th they have done so far. It has 0 shift.

Of course anything I might be interested in is either OOS or on backorder right now. At least the places that sell stuff below MSRP.

I haven't noticed the parallax issue but I might not know what to look for. One of those, "didn't know it was a problem until I read about it" things. Just googling "MRO parallax" suggests there's something to it since the first page is thread after thread about it. The things I skimmed talk about the extreme edges, which is probably why I never saw it..., why would I be aiming at the extreme edges?

Also, "Trijicon clearly states on their website, "Like all reflex-style optics, the Trijicon MRO is parallax-free when the dot and target are reasonably well centered in the optic's field-of-view, but when the reticle and target are substantially off-axis, there will be some parallax."

For me, both the pre 89K issue and parallax issues were unknown until I read about them. I'm sure different eyes are affected by these things differently, and people use their optics differently. Maybe I'm not training for situations that would exhibit these issues to me..., and I should be. Something to think about for sure.

Also looking at the Aimpoint PRO.
