Tippmann Arms ISS-16 Features The Tippmann Arms ISS-16 pairs a 16 solid 4150 steel ported barrel with an integrated suppressor housing delivering meaningful sound reduction without the bulk of a separate thread-on can. Because the suppression is built directly into the barrel assembly the ISS-16 avoids the added overall length weight and point-of-impact shift that can come with bolting on an external suppressor. The barrel is engineered for subsonic .22 LR ammunition where the integral design does the most work reducing report while still cycling reliably with high-velocity .22 LR rounds. Porting along the barrel bleeds gas progressively into the suppressor chambers rather than all at once helping manage both sound and pressure as the bullet travels down the bore. The solid 4150 steel construction gives the barrel the strength and heat tolerance to hold up to repeated strings of fire without sacrificing the accuracy a rimfire shooter expects from a dedicated .22 LR platform. Suppressor housing is machined from lightweight 6160 aluminum keeping the complete 16 assembly at around 18 oz so it does not add excessive weight to the front of the rifle. The ISS-16 is a direct fit for GEN3 Tippmann Arms platforms requiring no permanent modification to install and letting an existing GEN3 owner add integral suppression without reworking the rest of the rifle. An anodized and parkerized black finish protects the barrel and housing from corrosion and wear during regular range use keeping the unit looking and functioning like new well after break-in. Built and assembled in the USA the ISS-16 reflects Tippmann Arms focus on domestic manufacturing and quality control for its rimfire lineup. For GEN3 Tippmann owners this barrel is a purpose-built low-maintenance way to add integral suppression to their rimfire platform suited to backyard plinking pest control and training sessions where a quieter report matters.
