Gen II uses a different base plate geometry and is not compatible.\u003c\/p\u003e\n\u003ch3\u003eDo I need threadlocker for the .308 mag extension?\u003c\/h3\u003e\n\u003cp\u003eRecommended. The grub screw holds firm under normal use, but repeated heavy recoil from .308 loads can loosen it over time. A drop of medium-strength threadlocker (blue Loctite 243) ensures it stays put through competition and training.\u003c\/p\u003e\n\u003ch3\u003eIs the Pack of 3 the same product as the single extension?\u003c\/h3\u003e\n\u003cp\u003eYes — identical CNC-machined aluminium extensions, just bundled at a better per-unit price for shooters kitting out multiple magazines.\u003c\/p\u003e\n\u003ch3\u003eAre extended magazine base pads legal for 3-Gun competition in Australia?\u003c\/h3\u003e\n\u003cp\u003eExtended base pads are legal in most 3-Gun divisions including Tactical and Open. However, check your specific match rules for capacity limits, as some divisions cap rifle magazines at 20 or 30 rounds. Always confirm with your match director before competing.\u003c\/p\u003e\n\u003ch3\u003eHow much extra weight does the +5 extension add to my magazine?\u003c\/h3\u003e\n\u003cp\u003eThe extension weighs 109 grams — light enough to avoid noticeably altering the magazine's balance in a chest rig, mag pouch, or when inserted in the rifle. The 5 extra rounds of .308 ammunition add more weight than the extension itself.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Boss Components","offers":[{"title":"Single \/ Black","offer_id":54434470330652,"sku":"056-BLK-SGL","price":64.99,"currency_code":"AUD","in_stock":true},{"title":"Single \/ Blue","offer_id":54434470363420,"sku":"056-BLU-SGL","price":64.99,"currency_code":"AUD","in_stock":true},{"title":"Single \/ Red","offer_id":54434470396188,"sku":"056-RED-SGL","price":64.99,"currency_code":"AUD","in_stock":true},{"title":"Single \/ Gold Plated","offer_id":54434470428956,"sku":"056-GLD-SGL","price":64.99,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0722\/0835\/1516\/files\/308-5-mag-extension-base-pad-for-magpul-pmag-104822.jpg?v=1786853257","url":"https:\/\/magnumsports.com.au\/products\/308-5-mag-extension-base-pad-for-magpul-pmag","provider":"Magnum Sports","version":"1.0","type":"link"}
