Jim P from United States, TX Public Profile

Bought four, all arrived clean, rust free inside the bores and with undamaged threads. No headspacing issues. Only set up one so far and getting about 3/4 MOA with factory PMC 55 grain ammo. For a barrel this price that's more than adequate. Great for budget upper builds.

Rugged is consistently excellent. This is beautifully and perfectly (as far as I can tell) machined. Finish is beautiful and looks durable. Threads and mating surfaces all engage perfectly. Even the little plastic boxes these come in are perfect for storage. If you ever need help from Rugged their support is quick, friendly, and professional.

All of the QD muzzle devices are expensive compared to standard muzzle devices. When you're attaching and suppressor you don't want it working loose or giving you a baffle strike, so tolerances have to be much tighter than for a normal A2 flash suppressor.

Follow Rugged's installation instructions and you shouldn't have any problems. Don't use a crush washer.

What they don't tell you about this rangefinder is that the angular spread of the laser is fairly large, making it difficult to reliably measure small targets. Vortex doesn't provide a spec for the reticle size but I would guess it's around 30 MOA. If that's not enough of a problem, sometimes the rangefinder returns readings on objects outside of the reticle. (In my testing objects below the reticle seemed most likely to interfere.) Past a few hundred yards it is difficult to quickly get a consistent reading on a deer-sized target, especially if it's moving and there are intermediate obstacles. This instrument offers several filtering modes but none of them are all that consistent and none of them entirely compensate for the large beam divergence in this rangefinder. Ultimately, at the ranges where this unit works well you probably don't even need a rangefinder.

Another significant gripe is that the lowest brightness setting is still so bright that it washes out the view in dark conditions.

The housing is solid, the optics are very clear, and it does a good job at ranging buildings from hundreds of yards away with a completely clear line of sight, but nothing about it is enough to compensate for the problems it has with quickly and consistently getting ranges to typical target-sized objects in real world conditions where foreground and background clutter are both present.

Ordered these in November 2023 and received batteries with PD date of 10-2019, so half of that extra-long shelf life is already gone. Also arrived with broken/opened plastic shell on the front of the package.

The machining and finish on these barrels is excellent. Had they been packaged and stored properly they would have probably been excellent barrels. I ordered 3 of these, and on inspection 2 of the 3 had noticeable rusting at the muzzle ends of the rifling. This was detected on visual inspection of the muzzle ends with a bore light and confirmed using a bore scope.

These barrels arrived with vinyl caps covering both ends, probably sealing moist air inside. They were not packaged with silica gel or any other desiccant. The bores also appeared to be free of any corrosion protectants when they arrived. If Centurion had cut a hole in the breach end cap and dropped a silica gel pack into the plastic bag before sealing it, rust would probably not have formed.

I would not recommend this barrel to anyone who doesn't have the means to thoroughly inspect it for rust.

This is a fantastic scope for an AR-type rifle intended for the possibility of both CQB and pushing out past 100 yards. Only complaint is that the first one I got had a reticle that was broken into dozens of pieces and of course didn't work at all, but the vendor replaced it with a new one and was shocked it had left the factory that way. I believe I paid a couple hundred more for this than OP is selling it for now.

This scope is rugged, it's easy to use, and the glass is extremely clear. I compared this directly to a Gen2 Vortex Razor HD 1-6 (the Gen3's weren't out yet) and was immediately sold on this. I haven't used the Gen3 Vortex scopes yet so I can't make a comparison there, and someone looking for an LPVO scope should consider that as alternative to this because many people do prefer the Vortex. I find 8x to be plenty of magnification for an LPVO but the Gen3 Vortex goes up to 10x. That difference in magnification probably won't matter unless you're trying to push beyond 400 yards.

The eyebox is more than adequate at 1x and gets tighter as you increase magnification, which always seems to be the case with scopes. The red dot also remains visible as you begin to move out of the eyebox. Overall target acquistion up close is still very quick. I would say that if someone is having issues with this scope, that's probably something that can be overcome with more training. My theory is that people complaining about the eyebox are used to red dot sights and expecting to get

Video latency is the Achilles' Heel of the RH25 and many other thermal imaging scopes. iRay doesn't provide latency specs but I would estimate it to be around 200 ms. The result is that, if the user pans quickly with the device, the displayed image noticeably lags the direction in which the RH25 is pointed. This is fairly disorienting and limits the user's ability to navigate effectively using the RH25 in helmet mounted mode. The video latency also creates additional uncertainty about whether a target may have already begun moving at the time a shot has taken, limiting its use in ethical hunting. So for me the RH25 ended up being a very expensive handheld thermal camera.

But if you're a nighttime varmint hunter/pest exterminator who isn't concerned with some occasional wounding shots that aren't immediately lethal the latency may not be an issue for you at all. iRay is doing a lot of things right here and the image quality on this really is fantastic.

CONS
*Notic

Pros: Has a sturdy housing; solid well made rail mount; battery compartment opens and closes smoothly and easily while also sealing well; intuitive controls that are easy to manipulate in the dark; excellent image quality; nearly zero optical shift to the daylight scope. Good value compared to other clip-on options. Rubber on it seems to be of good quality but smells strange.

Cons: Tech manual doesn't cover some key aspects of the device well, like the fact that there appears to be a black bar on the left side of the screen that protrudes into the viewble area at low magnification (< 4x). In my setup the bar was no longer visible above 4x which is what Eotech lists as the lower end of the usable magnification range. (This will vary depending on how far the objective lens from the daylight scope is from the collimator lens of the clip-on.) Also, I don't think the useful magnification range is as broad as Eotech says. I found it useful down to 2.5x, which was the lower limit of my testing, but above 6x image quality deteriorates quickly and there's not much reason to increase magnification beyond that other than to make a 1FP daylight optic reticle more visible. At 20x it's difficult to see much image detail at all. And of course the price.

Overall I'd this is an excellent clip on but I would consider it best suited for medium range rather than long range use. Also, anyone considering getting an NV clip on should consider thermal instead. NV and thermal each have their own ad

I ordered two of these and they both arrived with plastic caps on both ends. Both bores were completely free of oil/corrosion inhibitor and were rusty, with rust at the muzzle end visible with a bore light. One of them looks like it might shoot OK if given the chance, on the other the rust looks substantial enough to affect accuracy. Still, I expect new barrels to arrive without visible rust.

They appear to be well manufactured but they do not appear to have been packaged well. A quick blast of corrosion inhibitor or Rem Oil before they were packaged at the factory would have saved these barrels. Also, it's usually not a good idea to plug up both ends of a barrel in storage. I've seen a number of barrels ruined this way. Any humidity that was in the air when they were plugged becomes trapped there, just waiting to condense and catalyze rust formation when the barrel inevitably gets cold during storage. A better approach is to seal them in plastic bags with ample desiccant.

The cerakote looks nice and feels smooth on the outside, but the texture of the inside surface where the bolt carrier rides is pretty rough. Some commenters on Practical Machinist recommend sanding the inside of these with fine grit sandpaper, but I hate to have to do that to a brand new part that's supposed to be finished. Other people recommend just shooting it, but they don't mention how abrasive the cerakote is likely to be to the bolt carrier. Haven't decided whether I'm going to try to sand the interior cerakote down or just return it.
