Sig BRAVO4 Battle Sight First Range Test

Sig BRAVO4 Battle Sight on Windham Weaponry SRC

Not to be overly dramatic, but my first range trip with the Sig BRAVO4 Battle Sight has got me rethinking my optic of choice for a go-to AR-15 rifle.

First, a little background… Prior to this range trip, I was convinced that the best optic for my go-to AR was a red dot sight. My thought process was simple… A non-magnified red dot would get me reasonably on target when shooting anywhere from 10 – 200 yards, which would surely cover the majority of likely scenarios faced in a SHTF situation. However, there is a major flaw with this thinking… I’m not being honest with myself when I say I can be “reasonably on target” at 200 yards when using a red dot sight. In fact, due to aging eyes, my accuracy with red dots really begins to suffer when shooting beyond 50 yards.

So, now that I have publicly admitted to my red dot limitations, let me show you why the BRAVO4 has me so excited. During this test, the BRAVO4 was mounted on the Windham Weaponry SRC. This was also my first time using Headwaters 223 Rem ammo, which is produced by FOG Ammunition.

It took me 10 rounds to get the BRAVO4 zeroed at 100 yards. Windage and elevation adjustments were quickly made using the knobs located on the rear top and rear right side of the sight. Once zeroed, I could immediately see that the 4X magnification of the BRAVO4 was going to make a huge difference for me. The following Birchwood Casey targets give you an idea of the accuracy I was able to achieve with this setup.

The target on the left was my first target after zeroing the BRAVO4. If you exclude the outlier on the right, the group size is 2.71″. The target on the right, which was my last group of the day, and very representative of my results with the BRAVO4, features a 1.67″ group. *I did make a few windage and elevation adjustments between these two targets.

Without a doubt, the sub 1.75″ groups I consistently achieved with the BRAVO4 are a dramatic improvement for me, when compared to my typical results with a red dot sight. And so far, I’ve only fired 120 rounds while using the BRAVO4. I suspect I’ll continue to improve with more rounds fired. Stay tuned for more updates…
