A presentation and review of the Double Bell M416 AEG by UK Airsoft and they have it in stock. Double Bell presents a robust HK416 family replica with metal externals like the SMR type handguard, upper and lower receiver, outer barrel, and buffer tube. The only polymer parts are the pistol grip and adjustable stock. The SMR rail, equipped with three rail sections, allows for customization of accessory placement or weight reduction. It also includes QD sockets for sling swivels and a full-length top rail for optics and folding backup iron sights. The muzzle, featuring a 14mm ccw thread, accommodates devices like tracer units or suppressors and comes with a birdcage type flash hider. Internally, it boasts high-quality CNC aluminium air seal components, a full steel tooth piston, and a quick-change spring system for easy power tuning. The modern rotary design hop-up ensures easy setting and consistent performance.
