So I may pick up a pvs27 soon. Depending on how I like the look of it compared to a pvs30. If I got a 27, and say I brought up the opportunity to trade it for a cnvd-lr? Or is that like trading a civic for a Mercedes?
Night Vision Would anyone do this?

I would trade a pvs27’s for a CNVD-LR all day. Unless you need the magnum rating. I love the Cnvd-LR
What are the upsides to the CNVD-LR over the 27 ? I thought the 27 was a better peace of kit? Or is it just a matter of weight vs the magnum rating ?

I would love to trade my civic for a Mercedes Benz my friends all drive Porsche's , I must make amends . Oh lord won't you buy me a Mercedes Benz . lol
My experience is the 27 does better on really dark nights. But with illuminators it doesn’t really matter. The LR is way lighter weight. The focus adjustment is amazing. It’s everything the 27 isn’t. The upside to the 27. I would put it at 15% better imagery and range. And you can mount it on a 50bmg. That’s it.
@Freedomfighter68 What about compared to a PVS 30 ?
I am kind of looking at clip ons myself and have been trying to decide which one to get.. saying all of them are the same price.. I was wanting something I could use on my MRAD. I don't want to throw down that kind of money and not be able to use it on the most long range gun I own

If your not shooting with anything bigger then a .308 parent cartridge. I would only buy a Pvs24LR. CNVD-LR. If I was running a .300WM or 338LM. I would do a PVS30. Preferably in white. 
. To use a pvs27’s i would want to be stationary or have a 50bmg and not give a shit about weight. Now adjusting focus on a pvs27’s is easier to adjust, then a PVS30 in my opinion.
I personally have a white 24LR for my .308 parent cartridges and lower. And a PVS30 for my magnum series

The recoil rating isn't just about how big a gun you can mount the unit to.
The 22s, 27s and 30s have a true floating internal suite. This not only lets them easily rate to 50BMG but also has a BUNCH to do with how well they stay calibrated during handling and bumping around.
This is a much more important metric to some than whether we are ever going to shoot it on stuff bigger than .308Win.
So far, the 22s, 27s and 30s have a consistently the best track record for POI retention during classes.

Interesting, and not the first time I've heard that. If you have experience w/ the 24LR, what has been your impression of it? I have read that they do not hold boresight very well.
Most of the 24LR units I have seen have phenomenal images. I have been lucky enough to see a good many with high end green tubes as well as WP. The ergonomics of the unit are nice and the image provided for the size of objective, etc. is really, really good.
The PVS-24 family of units including the LR all seem to have the same center technical suite. Something to do with the way the prisms are isolated and kept aligned seems to be less robust than the system engineered into the 22,27,30 units. I know some of the 24 family of clip-ons have been sent back for re-calibration, come back perfect and then have to go back again in 24 months.
There was one 3rd party guy in Idaho that would re-calibrate the 24LR prisms and he claimed he could institute "a fix" where they would retain alignment much better than factory...... I have no clue if true, just passing that along.
The 22,27 and 30 units can and do get knocked out of collimation or whateverTF it's called but it is a LOT less common occurrence with those.
Again, my opinion is that the 50 cal. rating is more about total unit service across the board rather than just how much recoil it is rated for.
I an not privy to engineering data and am certainly not an expert on this stuff but even a dummy like me can see trends if there is enough samples, incidents and time spans.

Contact FLIR and get info on where to ship to and pricing.
The original 22s and 27s will have O.S.T.i. markings on the main housing. Don't go looking for O.S.T.I. FLIR or FLIR service centers will service all 22s and 27s.
FLIR bought OSTI a few years ago so they could use their IP for the new gen clip-on thermals among other things.

Intellectual Property - Basically all of their patents, design, research and tech.
Most of the 27s had Pinnacle related tubes but I'm sure there are variants with others. I have no clue where you would go for any reliable source specs for their output. I would bet you are not going to obtain that from the company. Likely there are a handful of tech nerds in the industry that know all of that and would get moist just pondering the thought of such a discussion.
