- 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.
