Couldn't load pickup availability
The Cyclops Compensator for the Gen 5 Glock 17 and 47 has S-tier muzzle flip reduction. We achieved this by combining an optimized port with a large expansion chamber, mechanical leverage via ambi thumb rests, and 3oz of non reciprocating mass.
This is a compact frame mounted compensator with a large expansion chamber and single port.
This 50 state legal compensator is made for unthreaded barrels and is anodized black. It has an ambidextrous serrated thumb rest lower and modular interchangeable uppers. The lower was painstakingly designed with radiuses that match the frame so that it looks and feels like a seamless integration.
This compensator increases the dimensions of the firearm and will require one of the dedicated holsters available HERE.
Everything you will need for the install is included: locking block, screws, Blue Vibratite 121 thread locker, and an allen key.

Really nice but 1 minor issue. With the surefire 300 series the light becomes loosey goosey and will rattle all over. The rail on the compensator puts the light down and on gen 5 at least the trigger guard pushes the light forward. Without a proper rear brace the light rattles. There are multiple surefire 300 flashlights though. I may have to get a 300b, the screw fastener on that model may fix the issue. The ONLY issue. The finish is slick and beautiful, the fit is superb. The compensation is 50 state legal as a former illinois resident i can appreciate this. The weight and affect makes my G17 gen 5 top tier performance. Staccato who?
Love the cyclops on my G17, could tell the difference right away! Great machine work and looks awesome! The fit was perfect and easy to install.
Awesome product. I bought three of the cyclops compensators and they all work flawlessly.
Construction and fit is magnificent. And it will fit perfectly on a G47 pistol. Be aware, if you're running and X300A light from Surefire,the light will have to sit a slot further forward and will be pretty loose on the new rail. A 300B with the screw mount is a better option. Only ding against a 5 star rating.
