As with our entire Optima range, intelligent material selection and baffle design provide durable longevity and excellent noise reduction.\nIntended Use\nLightweight design ideal for Long range hunting and alpine hunting with standard and magnum energy calibres such as 270Winchester, 6.5PRC, 7mm Rem Mag and 7PRC. Simply more volume to provide more suppression than our smaller options. This suppressor is intended for hunting situations where shot strings are a few shots at a time and the temperature of the unit is kept under control. Combined with its optional brake endcap it can provide exceptional recoil and muzzle flip reduction, ideal for shooting from steep awkward positions in the mountains.\nDesign Features\n\nStainless steel boss section and finely machined stainless steel baffle core provides remarkable durability for such a light weight design. Super lightweight Aluminium alloy body completes a light weight suppressor.\nThe suppressor features a built-in first stage stainless steel muzzle brake which traps gas for recoil reduction and eliminates excessive gas erosion of the alloy components.\n50mm diameter body prioritises performance first and suits the format of both general hunting and long range hunting rifles.\nThis unit is designed for any calibre up to magnums such as 7PRC capacity, pressure and heat. In its weight class it is the industry leader for noise and recoil reduction.\n\nCaution must be exercised with magnum calibres to keep the temperature of the unit down by limiting shot strings to a few shots.\n\n\nModular design makes it possible to subtract or add a module to choose your desired length &amp; weight to noise reduction ratio.\n\nRemoving a module decreases the noise reduction effect by 3-5dB; depending on the calibre and barrel length.\n\n\nThis product makes use of our A-Lock thread adaptor system. Any thread is supported.\n\nSee link below to add an A-Lock to your order, it is not included.\nThe A-Lock can be affixed to your rifle muzzle allowing quick attach/detach of the suppressor. It also provides the ability to use the same suppressor across multiple rifles all with different threads (an A-Lock for each muzzle is required for this and with calibres up to that of the suppressor).\nThe A-Lock can instead be locked into the suppressor and the unit attached and detached like legacy suppressors (we prefer to do this for you by special request to ensure it is correct before use).\n\n\nThis suppressor can accept our optional Brake Endcap. \n\n\nSee link below to add the Brake Endcap to your order, it is not included. \n\nThe images show the suppressor with it attached at various lengths for comparison purposes.\n\n\nThe Brake Endcap significantly reduces recoil and even more significantly straightens out muzzle flip so that you can keep the target in sight through the recoil pulse. The effect is quite phenomenal.\nThe Brake Endcap increases noise by 1-2dB depending on factors such as the number of suppressor modules fitted, calibre and barrel length.\n\n\n\nOverbarrel(reflex) design with free-floating overbarrel section specifically designed not to affect barrel harmonics. \nImportant note on reduction performance: Unique to A-Tec, our suppressors are tested to the latest MIL-STD-1474D military standard which is the most stringent and difficult standard to test to. Research shows our competitors do not test to this standard. For comparing to competitors products we prefer to let our reputation do the talking but you will observe our suppressors performing 5-10% better for a stated dB and significantly better for dB reduction vs weight &amp; length.\nA-Tec have only one grade of precision: Match Grade. A-Tec suppressors are second to none for concentricity, straightness and fine dimensional tolerances. This is especially evident in our bore apertures which are tight to the projectile to maximise sound reductive effect. To get peak performance from an A-Tec suppressor, one's rifle muzzle must be correctly crowned, threaded and shouldered.\n\nSpecifications\n\n\n\nOVERALL PERFORMANCE\n31 DB(C) \n\n\nSILENCER WEIGHT\nUp to 394gm\n\n\nDIAMETER\n50mm\n\n\nOVER BARREL LENGTH\n80mm\n\n\nADDED LENGTH\nUp to 150mm\n\n\nTOTAL LENGTH\nUp to 230mm\n\n\nMATERIAL\nALUMINIUM, STEEL\n\n\nSURFACE TREATMENT\nBLACK ANODISED\n\n\nAVAILABLE CALIBRES\n6.5mm, .30\n\n\nMAX BARREL DIAMETER AT SUPPRESSOR\n23.7mm\n\n\n\nWhat comes in the box?\n\nSuppressor\nRear bushing (use only if desired for aesthetics or to reduce foreign items getting into the rear area of the suppressor)\nInstruction manual\nCurrently shipped in tough plastic case\n\nBe sure to add a A-Lock.

In this case the calibre of the suppressor must be equal or greater than the largest calibre rifle.\nThis means the adaptor is on the end of the muzzle, maybe affecting it's aesthetic if it is a thin barrel\n\n\n\nAdaptor locked inside the suppressor\n\nThis allows the suppressor to be attached using muzzle threads like legacy suppressors.\nWhen the suppressor is removed, nothing is left on the barrel.\nWe prefer to do this for you to ensure quality.\n\n\n\n\n\nThis requires a firearms licence to purchase; this must be presented on pick up, or for the item to be couriered to you a firearms mail order form is required.\nWe will contact you after purchase with the appropriate form and what is required.\n"
