Best Glock Compensator - Editor's Choice

The recoil compensators allow the shooter to stay on the target. Usually, Glock compensators are compatible with threaded barrels for quick and easy installation.

Why do we need a Glock compensator?

Recoil compensators, attached to the end of gun barrels, rifle muzzles, or cannons, can be integrals to the constructions as well. In all cases, these devices redirect propellant gases in a way out from the shooter to withstand recoil and to minimize unwished muzzle movement.

        How to choose Glock compensator

        • Before purchasing any compensator, make sure it has the same thread pitch and diameter as your barrel threads, as well as sufficient bore clearance for your caliber.
        • Check or measure the diameters of the compensator bore and used bullets, or simply pass one of your bullets through the entire bore of the compensator if you can before buying and installation.
        • The bore diameter of some compensators can be deliberately tight to ensure existing gases’ maximum usage.
        • To prolong the compensator life, it’s recommended to clean and lube it often.
        • Utilizing the bullets without an exposed lead on their base can prevent lead build-up in the compensators.

        How to Install Glock compensator

        • Make certain your rifle or pistol is unloaded and safe before mounting/dismounting.
        • Depending on the brand barrels and compensators, tools can be required or not for the installation and removal.
        • In some compensator types, while mounting, this device should be pushed completely back to the thread shoulder to ensure a superb bore alignment.
        • It is important to align the barrel threading with the bore axis, as improperly aligned threads could cause dangerous baffle strikes when the bullet is shot through the compensator.
        • The guide rod has a hole in it to hold the spring back to help install it into the slide.
        • Check all fitting dimensions of the crush washer, peel, and machining the comp shoulder, making the compensator corresponding to your preference.
        • After confirming all comps sizes with the rifle barrel’s ones, put it in the slide, remove it from the receiver, then degrease, dry threads of both the barrel and compensator, and coat them generously with the 272 Loctite, allowing time for curing. Any compound should be left in the barrel or comp bore.
        • The compensator should be screwed at once onto the barrel until there is no space for another full comp turn without it contacting the slide. Both the tops of the compensator and the slide should be aligned.\
        • If you need to remove a Loctite comp, heat the threaded surface evenly and slowly with a propane torch and carefully unscrew the muzzle device, remembering that it’s hot. Then clean the compensator and degrease it before any re-mounting.

        FAQ

        What does a compensator do for a Glock?
        Compensators for Glocks or other firearms allow the shooter to make precision follow-up shots, due to the recoil countering.
        Do you need a threaded barrel for a compensator?
        In most cases, yes, a threaded barrel is necessary to install a compensator. Suppressors can be attached to the threaded barrel of a tactical pistol as well, as a result, a longer barrel will deliver enhancement of a muzzle velocity. Earlier firearms have non-threaded barrels, so the set screws should be used additionally.
        Are pistol compensators worth it?
        Compensators are efficient at mitigating felt recoil and muzzle rise, allowing to get the sights back on target faster. Some shooters note that compensators help them minimize the flinching probability due to the decreased perceived recoil.
        Do compensators make guns louder?
        The compensators don’t make the volume, it happens because of the blast redirection more towards the nearest shooters, standing to the side of the muzzle. Ear protection or suppressor can help reduce the noise to the shooter.
        Are compensators illegal?
        Compensators are legal everywhere. Compensators are installed on a threaded barrel, which is illegal in California. Glock 21 should be a gen 3 to be permitted in California as the gen 4 or gen 5 are not approved there.

        Conclusion

        Check the compatibility of your rifle thread pitch, diameter, and your caliber bore clearance with the compensator’s ones in its specification. Because the same thread diameter and pitch are used on the compensators, which are bored for different calibers. It is also important to verify that you are installing a compensator with adequate bore clearance for your caliber. The compensators provide better shooting accuracy, taking care of your shoulder, still the ear protection should stay on your responsibility.
