Its aluminum barrel incorporates a full-length rail that supports the spear and forms part of the barrel structure.\u003c\/p\u003e \u003ch6\u003eRail design and function\u003c\/h6\u003e \u003cp\u003eThe rail is integrated into the barrel rather than fitted as a separate component. It supports the spear along the barrel toward the muzzle and aligns with the profiles of the trigger mechanism and muzzle, maintaining a continuous guided path. Because the rail forms part of the barrel structure, it also increases stiffness and reduces flex under band load.\u003c\/p\u003e\n\u003cspan itemprop=\"mpn\" hidden\u003e3243\u003c\/span\u003e\n\u003cspan itemprop=\"mpn\" hidden\u003e2611\u003c\/span\u003e\n\u003cspan itemprop=\"mpn\" hidden\u003e3247\u003c\/span\u003e\n\u003cspan itemprop=\"mpn\" hidden\u003e3253\u003c\/span\u003e\n\u003cspan itemprop=\"mpn\" hidden\u003e3244\u003c\/span\u003e\n\u003cspan itemprop=\"mpn\" hidden\u003e3204\u003c\/span\u003e\n\u003cspan itemprop=\"mpn\" hidden\u003e3245\u003c\/span\u003e\n\u003cspan itemprop=\"mpn\" hidden\u003e3252\u003c\/span\u003e\n\u003cspan itemprop=\"mpn\" hidden\u003e3236\u003c\/span\u003e\n\u003cspan itemprop=\"mpn\" hidden\u003e3237\u003c\/span\u003e\n\u003cspan itemprop=\"mpn\" hidden\u003e3242\u003c\/span\u003e\n\u003cspan itemprop=\"mpn\" hidden\u003e3246\u003c\/span\u003e\n\u003cspan itemprop=\"mpn\" hidden\u003e3250\u003c\/span\u003e\n\u003cspan itemprop=\"mpn\" hidden\u003e3251\u003c\/span\u003e\n\u003cspan itemprop=\"mpn\" hidden\u003e3248\u003c\/span\u003e\n\u003cspan itemprop=\"mpn\" hidden\u003e3239\u003c\/span\u003e\n\u003cspan itemprop=\"mpn\" hidden\u003e4288\u003c\/span\u003e\n\u003cspan itemprop=\"mpn\" hidden\u003e3249\u003c\/span\u003e","brand":"Rob Allen","offers":[{"title":"70cm \/ Closed Muzzle","offer_id":67952694001942,"sku":"KON-093-OZI","price":390.0,"currency_code":"USD","in_stock":false},{"title":"70cm \/ Open Muzzle","offer_id":67952694034710,"sku":"SJN-699-MUS","price":390.0,"currency_code":"USD","in_stock":false},{"title":"80cm \/ Closed Muzzle","offer_id":67952694067478,"sku":"SFA-398-WAZ","price":390.0,"currency_code":"USD","in_stock":false},{"title":"80cm \/ Open Muzzle","offer_id":67952694100246,"sku":"RAR-697-TPI","price":390.0,"currency_code":"USD","in_stock":false},{"title":"90cm \/ Closed Muzzle","offer_id":67952694133014,"sku":"ZYY-798-IGX","price":390.0,"currency_code":"USD","in_stock":false},{"title":"90cm \/ Open Muzzle","offer_id":67952694165782,"sku":"BUF-177-VRH","price":420.0,"currency_code":"USD","in_stock":false},{"title":"100cm \/ Closed Muzzle","offer_id":67952694198550,"sku":"WNU-617-TUJ","price":420.0,"currency_code":"USD","in_stock":false},{"title":"100cm \/ Open Muzzle","offer_id":67952694231318,"sku":"EXA-479-SRJ","price":420.0,"currency_code":"USD","in_stock":false},{"title":"110cm \/ Closed Muzzle","offer_id":67952694264086,"sku":"LGR-732-QCC","price":420.0,"currency_code":"USD","in_stock":false},{"title":"110cm \/ Open Muzzle","offer_id":67952694296854,"sku":"NXW-549-NZW","price":420.0,"currency_code":"USD","in_stock":false},{"title":"120cm \/ Closed Muzzle","offer_id":67952694329622,"sku":"VOA-902-FHU","price":420.0,"currency_code":"USD","in_stock":false},{"title":"120cm \/ Open Muzzle","offer_id":67952694362390,"sku":"ZQK-525-CSM","price":420.0,"currency_code":"USD","in_stock":false},{"title":"130cm \/ Closed Muzzle","offer_id":67952694395158,"sku":"MML-953-XZN","price":435.0,"currency_code":"USD","in_stock":false},{"title":"130cm \/ Open Muzzle","offer_id":67952694427926,"sku":"CKJ-150-SBN","price":435.0,"currency_code":"USD","in_stock":false},{"title":"140cm \/ Closed Muzzle","offer_id":67952694460694,"sku":"QKB-296-KEN","price":435.0,"currency_code":"USD","in_stock":false},{"title":"140cm \/ Open Muzzle","offer_id":67952694493462,"sku":"SDL-036-LKH","price":435.0,"currency_code":"USD","in_stock":false},{"title":"150cm \/ Closed Muzzle","offer_id":67952694526230,"sku":"FQT-982-QFR","price":455.0,"currency_code":"USD","in_stock":false},{"title":"150cm \/ Open Muzzle","offer_id":67952694558998,"sku":"WAU-346-WPN","price":455.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0715\/9680\/2326\/files\/d3ddf17d-8521-484e-b715-95ccb880be88.webp?v=1794410158","url":"https:\/\/www.neptonics.com\/products\/rob-allen-tuna-aluminum-speargun","provider":"Neptonics","version":"1.0","type":"link"}
