Probably the best option for a first collimator. It doesn’t make sense to spend a lot of money on equipment you’re just getting to know. On a low mount, it works fine with the iron sights on my submachine gun. Easy to install. Well-made product.
Vortex Crossfire Red Dot CF-RD2 - Black
A compact red dot sight designed for mounting on a 22 mm RIS/Picatinny rail. The housing is made of durable and damage-resistant aluminum. The use of seals ensures resistance to water and dust. The set includes high-profile and low-profile skeleton-style mounts, which allow the red dot sight to be mounted on various types of firearms, such as shotguns, pistols, and AR-family carbines. The red dot sight is powered by a CR2032 battery.
FMC multi-coated anti-reflective lenses, aiming dot
Applying Fully Multi-Coated (FMC) anti-reflective coatings to the collimator lenses delivers outstanding image sharpness at any time of day or in any lighting environment. Thanks to these coatings, users benefit from enhanced image definition and richer, more luminous colors.
Equipped with a 2 MOA red aiming dot, the sight allows for vertical and horizontal adjustments. A side-mounted turret provides access to eleven brightness settings, enabling customization of the reticle’s intensity to suit different lighting conditions.

Review summary
Users praise this red dot for its excellent value, solid build quality, clear 2 MOA dot, and easy installation. They appreciate the two included mounts, good compatibility with AR-15s, Scorpion Evo, and other platforms, plus reliable performance at 25–50 meters, durability in harsh conditions, and the lifetime warranty. Many consider it a great first optic and one of the best budget choices available. Some reviews mention issues with certain brightness settings, occasional shutoffs during heavy use, a battery cap that can loosen under recoil, and lens covers that fall off too easily.

The device itself is fine, but there are issues with the weaker brightness modes. Modes N1, N2, and 3 do not work. Night vision modes are not visible to the naked eye, but mode 3 should be working.
-
Really ok, does the job. The only thing is that you need to invest in better lens caps because they often fall off. But overall, for this price, it's probably worth it.
-
Nice collimator. I bought it for my Scorpion Evo 3. The mounting was hassle-free. It only took me a while to perfectly set the dot. I was doing it for the first time, so it took a bit of ammo :)
-
The collimator is definitely worth its price! Its build quality surpasses all Chinese replacements. On the Scorpion Evo or for a Glock conversion, it works perfectly at 25m. An additional plus for the convenient high mount.
-
Big plus for two mounts in the set—the high one can provide co-witness on a firearm, and the lower one is useful, for example, if like me, you have a conversion for an AK and don't need co-witness anymore. Optics are good, dot size for distances up to 25–50m (2 MOA) is fine.
-
A budget red dot sight, but of good quality and solidly built. It definitely surpasses all the cheaper Chinese alternatives. It's simply ideal for 9mm submachine guns. Handles distances of 25 and 50m with ease.
-
Nice, budget red dot sight, but with intensive use it sometimes turns off—one star less for that. The set includes 1/3 co-witness and low mounts, depending on your preference. It withstands rain, cold, and mud.

The Vortex Crossfire Red Dot CF-RD2 in black is a reliable and precise aiming tool. Equipped with a clear red dot, it makes quick and accurate target acquisition easy. Compact, lightweight, and durable, it's perfect both at the range and in dynamic tactical conditions. Great quality at an affordable price. I recommend it!
-
The best of the budget red dots. Solidly built, clear, and, as sometimes important, lifetime warranty. Solid sight mode controls (make sure to tighten the battery cap well because it can unscrew itself with shocks), simple mounting, easy to find a magnifier to add to the setup.

Really very good quality for such a price, intuitive operation and installation. Battery included. Additionally, according to the manufacturer, lifetime warranty. I definitely recommend it. My rating is 5/5.

The Vortex Crossfire red dot sight is what everyone sees, but for this price, there is probably nothing better in terms of value for money. It is a very good, solid, and sturdy optic that will do its job and look great on almost any rifle.
-
Unbeatable for the price! If you want a budget sight with high tier quality - this is the one. Direct rival to the Sig Romeo, it has the same ruggedness and features. Comes with a nice quality riser to keep you from breaking your neck! Super clear lens and reticule. Recommend it heavily.

The Vortex Crossfire Red Dot CF-RD2 Black is, as always, the most worthwhile option for a first red dot sight for an AR rifle. So far, everything is very good, nothing to complain about ;) Time to save for a magnifier!
