REVIEW: BROWE BCO 4x32 Combat Sight

Sure, please provide the text you would like me to translate.

Continuing our 4x Combat Sight comparison. The next candidate is, as announced, the Browe BCO - Browe Combat Sight 4x32. Is it an ACOG killer? We tested it.

#ACOGKILLER - that's what you'll find with the Browe BCO. Why? When the BCO hit the market, it was basically an ACOG with a battery. The forums were full of pros and cons. Some swear by the light collector on the ACOG (SHTF, Prepper, Never battery problems), others argued that the longevity of modern LEDs negates the battery problem and additionally eliminates the issue with the light collector (more on that in the Trijicon Review). Anyway, Trijicon has followed suit and now has two models with LED technology alongside the traditional light collector ACOGs.

The housing and design are closely related to the Trijicon ACOG, as we already mentioned in the Browe BSO Review (HERE) - the CEO of Browe used to work for Trijicon before starting his own thing.

The specifications are almost identical to the BSO: we have 13.2cm length x 6.7cm width with a weight of 481 grams.

Adjustments are made again in .5 MOA increments. The adjustment turret covers are secured against loss. The BCO is also waterproof, you can dive up to 42 meters with it.

Regarding the housing material, it should be noted that there are two versions of the Browe: the BCO (Browe Combat Sight) and the BTO (Browe Tactical Sight). Currently, both versions use aluminum, with the BCO utilizing Military Grade 7075-T6, while the BTO only uses "normal" 7075-T6 aluminum. Before switching to aluminum with the BCO, the sight had a TiCP-2 Titanium housing. This explains the higher price, so when making a purchase, pay attention to whether you are getting the titanium version or the aluminum one.

The integrated mount is from American Defense, has a quick release, and guarantees (tested by us as well) 100% zero return.

The tube on the right underside contains both the battery - the BCO has active illumination (more on that later) - and the programmable interface. Here, the brain of the combat sight can be reprogrammed. Additionally, a remote tapeswitch can be attached to control the illumination remotely, or other electronic devices like lights and lasers can be powered by the BCO's battery. This can also work the other way around - if there is a central power source, the BCO can be powered by it.

Browe has come up with an interesting feature for controlling the illumination: the so-called SIC (Single Intuitive Control). There is a button that, when pressed once, automatically adjusts the illumination of the reticle. This works excellently thanks to the Sensor (Target Light Sensor Technology) - the light adjusts to the surroundings and is never too bright or too dark.

If you want to switch to manual mode, press the button twice. Now the brightness can be adjusted in steps. Holding the button down turns off the light. It also turns off automatically if the BCO has not registered any movement for four hours.

The sleep mode reacts to the slightest movements and turns the light back on in the last selected mode. The minimum battery life is 775 hours at the highest brightness level, on average the light can be operated for 2,000 hours with a CR123 battery. There are ten brightness levels available for day use and three levels for night vision.

Here is a picture at the manual highest brightness level. The reticle is then so overlit that the shape is no longer recognizable, but even in the brightest sunshine, the target point is immediately visible in the field of view.

Of course, the BCO can also be used completely without light - the reticle is etched and quite visible even in normal sunlight. The field of view is 7°, which is 36.8 feet at 100 yards.

The options available (from left to right) are a .223 reticle, Horseshoe and Dot, and a .308 reticle.

In addition, there is the triangle (Chevron). The illumination can be chosen in red, yellow, blue, or green (only one color - so you have to decide before purchasing).

As accessories, there is a Killflash and dust covers. An optional accessory is a Docter Sight mounted on top via ring. This module can also be used on the BTO or BSO and due to the ring, it can be mounted at any angle.

We have discovered a technical error that the manufacturer should definitely address.
