Ensure your rifle’s chamber is within safe limits with the Forster 6.5 Grendel Field Length Head Space Gage. Designed for precision, this field gauge accurately tests the headspace of your 6.5 Grendel rifle. Excessive headspace can compromise safety and accuracy, making this tool essential for every gunsmith. If your rifle closes on a GO gauge, it indicates that it can safely accept SAAMI-spec ammunition. Conversely, if it closes on a NOGO gauge, you may have excessive headspace. With the Forster Field Gage, you can be sure your rifle is at the correct chamber size, preventing dangerous situations and ensuring optimal performance.
