Installing the brake on my competition rifle was straightforward. The brake comes with a set of shims of different thicknesses so you can properly time your brake to your barrel. Being able to use any crescent wrench along the length of the brake was a nice design feature as well.
I have tried and used in competition several of the most popular muzzle brakes on the market, including offerings from Surefire, Lantac, HIPERFIRE, VG6, Ferfrans, Bravo Company, and others. I believe they all work well at what they are intended for, which in the case of true muzzle brakes is to reduce the amount of muzzle rise and keep the sights on target for fast follow up shots and rapid strings of fire. In my opinion, these muzzle devices belong pretty squarely on competition rifles, as the advantages are obvious in a race against the clock, but are outweighed by the disadvantages present in a tactical, law enforcement or duty situation. The disadvantages being a decrease in FPS, and an increase in loudness, flash and concussion to those nearby such as your teammates, ESPECIALLY if used indoors. This is debatable obviously, especially if you are talking about a single person using the rifle for self defense, however that discussion is beyond the scope of this review.
Based on my previous experience with muzzle brakes in competition, the ZRODelta CIB Gen 2 works at least as well as the best of its competitors, and possibly is the flattest shooting muzzle brake i have personally used. You can see some close up video and slow motion footage below of myself and some teammates testing the brake at Panthera Training Center in WV.
I have to caveat the claim of the ZRODelta brake being possibly the best with the fact that all quality muzzle brakes work well, and the differences in performance between the best ones in the hands of someone with decent recoil management skills is almost negligible, although it is noticeable. As you can see in the video above, the muzzle is barely moving at all, and the sights stay on target very well. I will admit that the effort it took to keep the gun on target using this brake seemed to be slightly less than with other brakes, hence my claim that this may be the best brake i have used.
Final Thoughts and Rating:
Overall i think this is a very effective muzzle brake and it is well engineered to give a competitive advantage to anyone who uses it, and i will be keeping this brake on my competition rifle for now. However its cost ($199) is significantly higher than similar brakes on the market which also work very well. So the question is whether or not the amount of performance increase is on par with the price increase, to which i would say that no it is not. You can buy very good performing muzzle brakes for around $125 that perform very close to as well as the ZRODelta CIB Gen 2. However if you aren’t concerned about your gun budget, and you simply want the best performing brake on the market, then the ZRODelta CIB Gen 2 should definitely be on your short list of muzzle brakes.
