Color: Black
Style: Red - CYCLOPS Reticle
Been shooting since '98. Army, civilian, it's been a part of me for half my life and shooting red dots was actually how I found out I have astigmatism. Used red dots 90% of the time and while certainly not unusable, they always were blurry or had a starburst pattern. Didn't matter the brand (EOTech, Vortex, Aimpoint, etc), the red dot was always the same. For a while (prior to 2010-ish) there wasn't much to be done about it unless you wanted to shell out thousands for an ACOG. So I sucked it up and stuck with the blurry red dots. Until I got the Primary Arms SLX and let me tell you... it's like putting on glasses for the first time. You didn't realize just how blurry the world was (trees aren't just blobs of green and actually have leaves!). Its the same experience. Your red dot "world" snaps into focus and you can never go back. The Autolive feature is great, especially for a home defense rifle. Just turn it to the brightness setting you want and leave it. It will auto turn off and "shake awake" when you pick it up, already right back to your last brightness setting by the time you lift it up and aim it. It comes with 8 different mounting options but with everyone moving toward 2.26" these last few years, it feels like a "nice to have but never gonna use it" kinda option. Most people will set to the highest option, or the lower 1/3 cowitness for those who can't let go of that mount height. Many other will simply place it on a Unity FAST mount or a riser (like I did). The eye relief, which is the biggest criticism most have with prism optics (not unique to PA, just something all prism sights contend with) is really not bad at all. I think the criticism of them is greatly blown out of proportion. The eye relief is absolutely fine for every practical (and tactical) reason you can think of. Just place it about 2 to 4" away from your eye and you're set. You're not sniping with this sight, after all. It's designed for quick, rapid shots but *also* as the ability to reach out and touch someone if need be but that's not it's main focus. The only cons for me are I wish the illumination knob was on the right instead of left side. I get that this is so you can adjust it while keeping your right hand on fire controls but it very slightly juts out into your sight. No where near a deal breaker and if you have it appropriately close it your eyes will naturally blur it out of your sight picture but slightly annoying none the less. The illumination knob is also VERY tight, especially when you first adjust it. I thought maybe it had a push-pull locking mechanism but nope. I just downed some spinach and cranked it harder. I appreciate that there's no slop or play but PA could make it just a tad looser. The problem is mainly because there the knurling on the knob needs to be a bit more robust. There's just not enough texture to match the amount of torque you need. Of course this is all moot because the GLX is coming out this summer (2024) which does away with the knob all together and replaces it with buttons. So I guess I'll be chipping out another couple hundred bucks later this year :D In the meantime, this optic is just about perfect for all my needs and the prism sight finally does away with the burry, headache inducing, issues I had to live with. The second con is the mounting option, specifically why the prism sight has a different, proprietary, mount than the standard Aimpoint Micro mount so many companies now use, including Primary Arms (non-prism) red dots. This is still an issue as their upcoming GLX uses the same prism mount and not the red dot micro mount. Honestly curious why this is because it seems like a universal micro mount many red dots are moving towards will only be a benefit the prism crowd. But for whatever reason we're locked out of that game. Sure, companies like Unity make a prism mount and their risers are truly universal, but it feels like prism sights are just weirdly out of step with the rest of the red dot market when it comes to how they mount. But the upside is that all of these "cons" are really just the most minor hiccups. They barely qualify as complaints or even annoyances. The fact is this sight is the most incredible red dot you can buy, especially if you have astigmatism.

Received with great protective packaging. High end component and materials. Very clear glass, etched reticle alignment is perfect and impressive brightness. All adjustments are nice and tight and I'm sure they will loosen up with time to some extent. Accuracy of reticle at ranging marks was spot on. Very impressed with materials and workmanship of this optic and I will likely be purchasing more from this company. Durability remains to be seen, but I'd wager it will be extremely sturdy and capable of long term reliability.

This little optic is nice! the glass is super clear and you can tell PA is producing great products! Reticle is nice (maybe a little too small for me) but no problems at all! The light settings are great but the only main issue I have is that the focus ring is a little tight! Great value and competitive! Will be trying out other optics from Primary Arms...

Very impressive. Easy to install and the options in mounting are very helpful. It's on my keltec ks7 12 gauge shotgun. The shake awake is awesome and everything is just as effective even without the light turned off. My eyes are older and the etching of redicle is crystal clear. I also ordered the honey comb glint/ glare cover for it. The quality seems very well made. Adjusting knobs are a little tight ( but it's brand new and it will loosen up in time). All in all I have yet to take it to range because I just got it yesterday. But I am quite sure it will be fine for me anyway. To each their own , but I would recommend this optic for sure.

Great little optic. The finish was spot on good price fro the quality of optic. I sent it back because I decided to go in a different direction. If it is what you want, it’s great.

These sights are very nice. I do wish there were more choices as to reticle design. The prism scope DOES handle my astigmatism WAY better than red dot sights; however, that seemingly mandatory half moon reticle often obscures targets at times, unlike a simple red dot reticle. When I'm trying to sight on a small target at much distance, I lose the target in all that big half moon and dot. I'd love to have this same sight with JUST the dot, and I prefer the green dot.

Excellent optic, clear glass, etched reticle saves $$$ on MBUS sights, chevron comes to a point instead of taking up 2 MOA like a red dot. Better all the way around.

The clarity and precision of this glass is unbeatable. The light level’s ability is perfect. I have it on a Henry Big Boy X 44 mag. Paired it up with a clip on thermal. It’s great- but beyond 50 yards I wish I’d have gotten at least a 3x.
