I manufacture these from Stainless Steel. They replace the standard grip screw and have an internal set screw to adjust the trigger pull in your AR15, AR 10 and M&P22. There's no need to tap your receiver for a set screw which can make the grip threads loose. Just simply replace the grip screw and adjust. They help eliminate pre-travel, creep and help reduce the pull weight on standard Mil-Spec trigger groups and can be used with many aftermarket triggers as well. The adjusters can be used alone or as part of a complete trigger job.Can also be used on some aftermarket triggers or two to reduce or eliminate the first stage, but results may vary.
The more you buy, the more you save.They are available for individual sale or in bulk quantities for resellers. As low as $10 each when you buy 10 or more. Also have extra long Allen keys available to use to adjust.
This video shows how to install and correctly adjust my AR 15 trigger adjusters. It also shows how much you can expect it to shorten your trigger pull. They can be used as a stand alone part or as part of a trigger job.
