Color: Flat Dark Earth (FDE)
Style: Red Raptor 5.56/.308 Reticle - Yard
The strength of this optic is in its daylight brightness and ACSS Raptor BDC reticle. It works very well, has 0.25 MOA adjustments with positive clicks that don't require any special tools to adjust. I just used the case rim from spent cartridges. The glass clarity is very good, though maybe not quite as clear as the very best prisms. However the value is way better with these, as you'll pay a huge premium for marginally better clarity. The primary weakness of the optic is the mounting hardware. You have many options, but the durability is probably not going to be fully duty grade like a Trijicon. But it's compatible with standard mounts so it's upgrade ready in that regard. I'd like to see a QD mount option, since the eye relief is good but still means you'll want to have the optic as far back on the rail as possible, which means it's hard to have backup irons also mounted behind the optic. It would be nice to be able to remove the optic in the field and access BUIs placed in front of the optic. Offset irons are a possibility but not what I prefer.

I've had it for almost a year now, love everything about it. Glass is clear, illumination is bright, holds zero after hundreds of rounds. Lost the battery cap on the range one day, PA replaced it no questions asked. Excellent optic. Easy to use. Light weight. Low profile. Very accurate. Super durable, dropped it a bunch without losing zero.

Set it up on my AR pistol. It's really good for quick shots while target shooting.

I really like a red dot sight for their ability to be mounted practically anywhere. However my astigmatism makes them look like red blobs now since my eyes have gotten worse. So I tried some prism sights and like a regular rifle scope I do not have the same issues as a red dot sight. My only issue is that they need to be treated just like a traditional scope in regards to eye relief. Once I got past the more restrictive mounting options I was sold on prism sights. These Primary Arms SLX sights are approximately half the weight and size of my older prism sights which are made by Burris. The sheer amount of mounting options that come standard with these is fantastic as well! It appears that some other companies are making some similar small lightweight prism sights as well so only time will tell how these stack up against the competition. The different color illumination options as well as the different reticles available are also huge pro's in my opinion.

Put this on my RDB, loving it so far. Pros: Less than half a pound weight. Clear glass with a nice reticle. Bright illumination with long battery life and shake awake. Generous eye box. 3x is a great magnification out to 3-400m. Cons: Illumination of the reticle is noticeably uneven, especially at lower brightness levels.

Very happy with this sight. Works well for my old eyes and is nicely accurate. Good quality and rugged as I have already dropped it (butter fingers). Great option for those that need a nice sight and reticle but don't want to pay a fortune. Also it is nice that the reticle is etched so is there even if the battery dies. Clarity of the optic is surprisingly good.

Keep in mind the chevron is small, ranging is more practical if your in an fixed ambushing position, though useable on the 3x for ACSS. With the 1X models, do not buy w/o looking thru one first. Even with corrective lenses the chevron on a 1X ACSS may look like a malformed "-" or more likely ".". It IS that small, Yes even after adjusting the diopter, suite the background. Most reviewers ignore this fact intentionally. The size of the ACSS reticle in the advertising is exaggerated for the 1X to 3X models. But at 1X the Chevron is ridiculously small unless you still have 20-10 vision. Your ammo needs to be compatible too. Nice scope if it fits your needs. For me a light/compact handy rifle rifle, fun but can be pressed to do more.

I have 2 of these now. I got the first one when they were first offered and mounted it on a Tavor I shoot regularly. I've had no issues from that scope at all. Holds it's zero and is functional 100%. I just bought another for an ar build and had it sighted in , in 5 minutes at 100 yards. These are worthy scopes and durable. Worth the money.
