.17 HMR Heavy Buffer Upgrade
The .17 HMR heavy buffer upgrade is a replacement for the standard buffer contained in the recoil cassette and should be used when the rifle features a lightweight fire control group only. This stainless steel, heavier buffer properly balances the weapon when the trigger features a lightweight hammer and/or lightweight hammer spring and will result in reliable cycling of the action. Failure to use this buffer upgrade with lightweight trigger components likely will result in a failure to feed or other issues. Use of this buffer upgrade with a standard-type trigger is not necessary or beneficial. You may view the installation instructions for this part here on our web site.
Please read our .17 HMR Trigger Function Notice news release for a full description of this requirement.
