BT DELTA UPGRADE KIT
Transform your standard BT-4 into the ultimate close-quarters powerhouse with the Delta Elite Upgrade Kit. Crafted for players who demand authenticity, performance, and intimidation on the field, this kit delivers the look and feel of a real Special Forces submachine gun—without breaking the bank.
From the moment you snap on the precision-machined barrel shroud, you'll notice the difference. The aggressive contours and matte-black finish command attention and strike fear into opponents' hearts. Paired with a collapsible tactical stock, your marker now offers rock-solid stability when you go full-auto or pump out rapid single shots. Whether you're storming a bunker or holding a tight hallway, the adjustable stock lets you find the perfect length for fast transitions and tight turns.
Need room for optics, lights, or grips? The top and side Picatinny rails on the barrel shroud give you endless options. Mount a reflex sight for lightning-fast target acquisition, clip on a flashlight for dimly lit arenas, or attach vertical grips to tame recoil and improve control. And because it's machined from lightweight, aircraft-grade aluminum, you won't feel weighed down as you sprint, dive, and flank.
At the heart of this upgrade is the Apex-ready barrel—engineered to accept your choice of Apex tip (sold separately) for next-level accuracy and range. Simply swap in your tip of choice, reattach the magazine, and you're ready to dominate every engagement. Installation is a breeze: no gunsmithing, no special tools—just bolt it on and start shooting.
Whether you're a veteran looking to freshen up your gear or a newcomer aiming to make a statement, the Delta Elite Upgrade Kit turns any BT-4 into a battlefield legend. Don't settle for stock—upgrade to Elite and own every fight.
