Double Bell TTI M4 (Custom Grip and 1-4*20 Scope - Black - 058M+) with Pre-Installed Storm HP-R HPA System

If you want to skip the endless gearbox shimming and jump straight into elite-tier airsoft, this fully loaded, competition-ready carbine is built for you. The Double Bell TTI M4 (Custom Grip and 1-4*20 Scope - Black - 058M+) with Pre-Installed Storm HP-R HPA System brings together aggressive race-gun ergonomics, high-pressure air efficiency, and crystal-clear variable magnification in an all-in-one package designed to dominate both fast-paced CQB arenas and extended woodland skirmishes across the UK.

At the core of this build sits the pre-installed Storm HP-R HPA engine, completely eliminating conventional AEG gears, pistons, and motor wind-up. Running on regulated high-pressure air via a grip-line connection, it produces instantaneous, hair-trigger response with virtually zero mechanical lock-up. You get lightning-fast semi-automatic double-taps alongside fully adjustable, consistent shot-to-shot velocity that ensures strict site-limit compliance on any chronograph while giving you laser-flat flight paths downrange.

The rifle’s exterior features the legendary TTI-style receiver and lightweight, skeletonized handguard, precision-finished in non-reflective tactical matte black. A custom high-traction pistol grip provides an ultra-secure, fatigue-free hold even when running tactical gloves in wet British weather. Along the full-length top Picatinny rail sits an included 1-4x20 variable low-power optic (LPVO) mounted on a cantilever base. Dial it down to 1x for rapid, both-eyes-open room clearing, or smoothly crank it up to 4x to spot, track, and engage distant targets tucked behind deep tree lines with total clarity.

Rounding out the package is an adjustable multi-position stock for quick length-of-pull adjustments, an aggressive compensator, and a high-capacity magazine ready to feed standard 6mm BBs flawlessly under rapid fire. Pair it with your favourite HPA tank, regulator, and airline, and you have an unstoppable, turn-key primary that looks stunning on the rack and shoots rings around traditional electric rifles on game day.
