Double Bell M416 AEG Airsoft Rifle with Adjustable Hop-Up - Desert Tan (BY-812S)

For players who prefer to control the field from the midline, the Double Bell M416 AEG in Desert Tan (BY‑812S) brings length, balance, and solid internals together in one no-nonsense electric rifle. With its extended build and precision-focused inner barrel, this platform is tailored for medium-range dominance while still offering enough agility to stay relevant when things close in. Whether you're anchoring lanes or supporting a push, it’s the kind of rifle that feels ready for whatever comes your way.

Built with a full-metal receiver and quad-rail handguard, the BY‑812S has the heft and feel of a real 416 platform. The only polymer you’ll find is in the grip and stock — right where it helps reduce fatigue without compromising realism. Steel is used generously too, including on the fire selector, charging handle, magazine shell, bolt catch, and screws. It’s this mix of material quality that gives the rifle a true “combat tool” vibe, not just a replica look.

Internally, you’re working with a Version 2 gearbox supported by 7 mm bearings, delivering a smooth, consistent firing cycle. The inclusion of a quick-spring-change system means adapting to site limits is straightforward — no need to crack the gearbox open. Whether a field needs you running at 330 FPS or 350 FPS, you can swap springs in minutes and stay in the game.

Precision is where the M416 Long stands apart. A tightbore 6.02–6.03 mm inner barrel runs approximately 390 mm in length, feeding an adjustable rotary hop-up unit that holds its setting under fire. Expect solid groupings out to 40 metres with good ammo and hop-up tuning. At the muzzle, a 14 mm CCW thread gives you full freedom to attach tracers, suppressors, or other accessories without needing adapters.

On the exterior, this rifle keeps your options open with multiple RIS/Picatinny rails on the handguard and top receiver — perfect for fitting optics, vertical grips, PEQ boxes, or lasers. Flip-up iron sights are pre-installed for quick deployment if you're running optics low or need a backup aim system. The functional bolt catch gives realistic action and quick access to your hop-up when adjustments are needed mid-game.

The stock is adjustable and fitted with QD sling points for right or left-hand carry setups. It balances the rifle well and provides a secure cheek weld for consistent shooting posture. Power is delivered through a rear-wired setup, and a stick LiPo or NiMH battery fits into the buffer tube area — no rattling, no awkward wiring to battle with before a skirmish.

It comes out of the box chronoing around 330–350 FPS with 0.20g BBs, making it field-ready for most UK sites without immediate upgrades. The included 300-round metal hi-cap mag ensures you're not reloading every two minutes, and it's compatible with standard M4/416-style AEG magazines.

In short, the Double Bell M416 BY‑812S is a dependable and adaptable airsoft rifle for those who value consistent range, robust build quality, and the ability to tweak performance as needed. It’s a solid platform for both new players who want to grow into their kit and experienced skirmishers looking for a budget-friendly DMR-style base gun that doesn’t skimp on the essentials.
