I've also been tempted on and off over the years by also getting a ZP5 with the MR4 reticle purely for long-range competition, partly as the scope overall is just so good, and partly as that would then mean a level of cross-platform familiarity. The MR4s also come up for sale secondhand more often, and were also part of the deep discounts a few years ago as distributors changed, so they've been available at very reasonable prices.
I think a few thing are worth noting here, and to build a bit on what
@RockAndSage said above. I think I've covered these before, but they could be useful for
@ID_Matt,
@JohnJohnson, and others considering the MR4:
When the ZP5 came out, some key people on the Hide spoke highly of it - in general, BigJim did about the rest of the package, but just didn't like (or perhaps understand?) the THLR reticle; Dave from the JustFnSendIt podcast ran one, and Bill/Glassaholic also spoke highly of it. It's worth digging through those posts - especially doing a keyword search for 'ZP5' with Glassaholic as the poster, to see just how well it was regarded. As just two examples, it was farily common for people to say that the ZP5 was superior optically to the ATACR 5-25, and held its own against ZCO.
I think CS Tactical was one of the main dealers for the ZP5. They seemed to rate it highly, but then dropped it from inventory. From memory, they made some semi-cryptic comments on the Hide that suggested they'd seen some reliability issues - but their lack of specifics didn't read 'right' to me, and they became a dealer for another alpha scope brand about the same time, so it just looked a bit muddly. And the PRS crew, often in want of the next shiny thing, the thing that has the most hype, or the brand that will keep them in the cool kids club (or in sponsorships) seemed to move on to other things. In any case, it would be good if those here using the ZP5 could post about any issues.
In terms of the THLR reticle being optimised for hunting - we need to remember that it was also possibly designed for military use, with one of the early videos (now deleted) apparently showing the reticle in that application. I've posted about this once or twice, and there's not much about this online. I don't know that Thomas has commented on that here, and I wouldn't expect him to. But if that was part of the design intent, then some of the reticle elements make more sense - and some add to its application for hunting.
