GHK Colt Licensed Mk12 Mod 1 Gas Blowback Airsoft Sniper Rifle by Cybergun

The GHK Colt Licensed Mk12 Mod 1 is a premium gas blowback sniper-style rifle that faithfully recreates the iconic Special Purpose Rifle (SPR) with attention to detail, performance, and realism. Produced by GHK and licensed by Colt, this full-metal replica blends authentic weight and ergonomics with modern airsoft internals—making it an ideal choice for collectors, serious marksmen, and players who want a high-fidelity GBBR platform with precision out of the box.

Authentic Construction, Realistic Feel

Built with a full metal upper and lower receiver complete with stamped Colt trademarks, the Mk12 Mod 1 feels like the real deal. The CNC-machined 18" steel outer barrel and upgraded CNC steel bolt carrier add durability and scale realism that you can feel every time you shoulder the rifle. The fixed M16-style stock provides a comfortable cheek weld and a bottom sling loop for secure carry during long sessions.

Precision Barrel & Adjustable Hop-Up

With a 455mm inner barrel and a new hop-up unit design featuring a quick adjustment tool, the Mk12 offers tight grouping and consistent trajectory when tuned correctly. The fixed hop-up lets you dial in elevation precisely for 0.20–0.30 g BBs, while the long inner barrel helps maximize effective range—making this GBBR suitable for designated marksman roles and disciplined field play.

Tactical Rails & Optics-Ready Layout

A flat-top receiver simplifies optic mounting and, paired with the 12" free-float RAS, gives you ample real-estate for bipods, lasers, grips, and large optics. The full length top rail and free-float RAS conform to the Mk12’s purpose-built role: a stable, accessory-ready platform that keeps optics zeroed and accessories modular for mission-specific setups.

Upgraded Fire Control & Bolt Group

GHK equipped the Mk12 with an upgraded CNC steel fire control group, hammer, and bolt carrier for solid, reliable operation. The gas blowback action produces crisp cycling and a satisfying recoil impulse that mimics the rhythm of a full-size gas rifle. Compatible with standard GHK M4 / AR-15 / G5 series magazines, feeding and maintenance are straightforward for players familiar with GHK platforms.

Field-Ready Ergonomics & Sights

This model includes flip-up low-profile fixed front and adjustable rear iron sights, offering a dependable backup to any optic you mount. The comfortable controls, bolt operation, and ambidextrous handling make the Mk12 easy to operate from supported positions or offhand when needed. The rifle ships with a 20-round green gas magazine to get you started straight away.
