First Strike T15 Full Auto Upgrade Kit
Unleash the true potential of your First Strike T15 with the all-new Full Auto Upgrade Kit. Engineered by First Strike Arms—the global leader in precision Milsim markers—this drop-in module transforms your rifle into the ultimate battlefield companion. Whether you’re laying down suppressive fire or executing surgical strikes, the T15 Full Auto Upgrade Kit gives you complete control and unmatched reliability.
Installation takes mere minutes. Simply swap in the FS Module and you’re ready to rock both semi-auto and full-auto modes via an intuitive selector switch. No gunsmithing, no fuss—just pure performance. Behind its sleek housing lies a high-flow bolt sealed with an O-ring for rock-steady shot consistency, even under rapid fire. A beefed-up striker buffer absorbs recoil and reduces wear, so you can rain down paintballs all day without worrying about breakdowns.
Game-changing versatility sets this kit apart. Dial in your rate-of-fire from a conservative 7 balls per second for delicate paint or fragile rounds, all the way up to a blistering 20 BPS when you’re firing robust First Strike ammunition. This unique, adjustable mechanical full-auto system ensures you never sacrifice firepower for finesse—or vice versa. Engage in close-quarters mayhem with blistering full-auto spreads, then switch back to semi-auto for precision pick-offs at range. Your opponents won’t know what hit them.
Durability is built into every component. Crafted from premium materials, the FS Module withstands harsh field conditions, extended skirmishes, and the occasional accidental drop. Maintenance is a breeze: quick-release components and standardized internals mean you spend less time wrenching and more time playing.
Transform your T15 into a dynamic, dual-mode powerhouse that adapts to any mission. From weekend warriors to seasoned Milsim competitors, players at every level will appreciate the upgrade’s straightforward installation, unrivaled reliability, and customizable firepower. Elevate your game today—because victory favors the prepared.
