The Archon compensator does a good job as a compensator with muzzle rise in the same range as most of the other highly rated comps. This one, however, fits perfectly with the Glock frame either Gen 3 or Gen 4/5. The visible flash (big deal at night) is less than some and quite acceptable. I do, however, recommend using a weapon light if you plan on shooting in low light to minimize the detrimental effects of flash (I also use the Holosun red dot for the same reason. low light shooting). One of the absolute greatest features of the Archon Comp over ALL others is the way it is secured to the barrel. Instead of set screws that require loctite and tightening into the threads of your very expensive, threaded match-grade barrel. If you tighten a set screw into the barrel threads, your barrel can now only be used for that. The Archon splits the comp along the threaded portion and uses two set screws (no need for loctite) to essentially clamp the comp onto the barrel. I takes literally two minutes to install and one minute to take off. Unlike the other comps I have used, i can easily remove the comp to properly clean my barrel and reinstall with ease. Best comp ever!
