Description.

The Double Bell SCAR-H M-Lok arrives with the look and heft you'd expect from a scaled combat rifle, and it behaves like an electric rifle that wants to be taken seriously on the field.

Built around a robust full-metal upper and a nylon fibre reinforced lower, the 804S wears its desert tan finish well — low profile in scrub and appropriately tactical on open terrain. If you search for an electric rifle that balances realism and gameability, this one deserves a long look. The M-LOK handguard reproduces real SCAR fittings and gives you room for a foregrip, light, or a quick-attach bipod without turning the rifle into a brick.

At first handling you notice weight and balance. The Double Bell tips the scales like a proper battle rifle: expect either ~3.1kg (3100g) in one spec set or the factory sheet’s heavier 3700g depending on the batch and installed hardware. That mass translates to steady aim and less flinch during follow-ups — useful when the engagement window is tight and you want your tracer to stay on target.

Externally, the SCAR-H M-LOK replica keeps period-correct cues: the charging handle, the sculpted receiver, ambidextrous controls and the distinctive stock profile are all present. The folding, telescoping stock collapses for tight building work, then extends smoothly for two-handed stability in the open. The 20mm rail sections forward of the handguard allow optics or back-up iron sights; the M-LOK mounting points accept smaller polymer accessories where you prefer them.

Internals are friendly to tech-minded players. The rifle ships with a V2/M4 style gearbox. The hop-up is adjustable, which matters: dial the hop for 0.28g BBs and you’ll see the effective range stretch. Out of the box performance figures vary by spec: one site quotes ~370fps (approx 1.26J) while another notes the UK-compliant tuning at 0.98J or below; check local legal limits and retailer notes when finalising a purchase.

Feeding comes from a multi-bullet dial / hi-cap magazine design. Some listings mention a 300-round hi-cap; others reference a dial magazine holding roughly 180–400 rounds depending on the interpretation of the manual — in short, you’ll get sustained fire without constant reloads, which suits a support/DMR role in pickup skirmishes. The magazine sits and locks in like the real pattern, and reloads are unambiguous even under stress.

Electrically, the rifle accepts small Tamiya connectors with recommended batteries varying across documentation: the product note suggests 7.4v LiPo with Small Tamiya it can take 11.1v LiPo for maximum cycle speed (battery not included). The motor is described as high-torque in the factory spec, which helps with heavier springs or if you push for a mid-range build; it’s also reasonable for semi-biased play without burning amps on light springs.

Field usability is pragmatic. In CQB the folding stock and short profile (listed lengths vary between ~815mm and 860mm) make the gun compact. Outdoors, the extra weight and longer 340mm inner barrel variant give better long-range stability and consistent groupings. In team play it works well as a designated marksman / support hybrid: you can hold angles, suppress an approach with hi-cap sustained fire, or pick off medium-range targets with a tuned hop-up and heavier BBs.

Upgrade potential is straightforward. The V2/M4 gearbox architecture — plus a metal gearbox shell in the premium spec — means standard hop units, tightbore barrels and high-quality piston sets are compatible. Want a switch to MOSFET/EFCS or an upgraded motor? Both are routine for a tech who likes to refine trigger response and battery efficiency. The barrel thread listed (14mm) also makes aftermarket suppressors and tracer units an easy fit if you want to dress the barrel without permanent modifications.

Realism matters here. The Double Bell SCAR-H M-LOK doesn’t pretend to be a collector’s exacting museum replica; instead, it replicates the operational feel and ergonomics that players crave. The M-LOK kit reproduces the look and mounting pattern you expect from genuine PMM-style components, and the tan finish reads correctly on a tactical rig. Controls fall where instinct expects them to — that reduces mistakes during reloads or weapon manipulations under stress.

For whom is this rifle best? If you’re a squad player who wants an Airsoft AEG that can double as a DMR and a support weapon, the 804S is a pragmatic choice. Historical roleplayers who prize form factor will enjoy the visual fidelity; milsim operators appreciate durable construction and upgrade pathways. Newer players will find it forgiving as a baseline AEG, while experienced techs will like the parts compatibility and the scope for tuning.

Manuals, batteries and chargers are not included, so budget for those basics. Expect the package to include the rifle and one magazine as standard; some vendors add a basic manual and mounting hardware.
