For instance, unsupported brass fired in a rifle action with excessive headspace can rupture, allowing gas to blow rearward like a rocket exhaust.\u003c\/p\u003e\n\n\u003cp\u003eBecause your safety is on the line, Forster Headspace Gages, including their 5.56 GO FALSE GO gauge and other Headspace Gauge 5.56 models, are made with painstaking care and exacting manufacturing standards to ensure accurate testing of your rifle's chamber. If a rifle closes on a GO gage, such as the 5.56Headspace Gages that adhere to S.A.A.M.I. standards, the rifle chamber will accept any ammunition that is made within S.A.A.M.I. (industry standard) specifications. If a rifle closes on a FALSE GO gage, the rifle chamber might have excessive headspace. Most gunsmiths chamber a rifle's headspace between the GO and FALSE GO dimensions. If a rifle closes on a FIELD gage, the rifle chamber is dangerously close to or already over the S.A.A.M.I. specified maximum chamber size. When considering the specifics, the Forster Headspace gauges, especially for 5.56, are invaluable tools for ensuring safety and precision.\u003c\/p\u003e","brand":"Forster Products","offers":[{"title":"HG556NATOMAX \/ Reloading Scales \u0026 Powder Accessories \/ Forster Products","offer_id":43118542225513,"sku":"11696012","price":45.81,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0659\/8341\/4377\/files\/CT_FPHGNATOMAX.jpg?v=1777410451","url":"https:\/\/westerngunstore.com\/products\/forster-headspace-gage-5-56-nato-1-4736-plus-zero-minus-0003-maximum-chamber","provider":"Western Gun Store","version":"1.0","type":"link"}
