A&K Masada-4 Airsoft AEG Rifle with Adjustable Stock in Black (Repaired Rifle)

The A&K Masada-4 Airsoft AEG Rifle in Black is a full-length, DMR-style platform with a solid metal upper receiver, adjustable PRS-style stock and plenty of space for optics and accessories. This particular rifle is being sold as a repaired model and has received a new M100 spring along with a complete rewire to Deans connectors. It is a substantial electric rifle aimed at players who prefer a longer, more stable setup for woodland games, defensive positions and medium-range engagements. Please note that one of the fire selectors will not remain in position, so buyers should take this known issue into account before purchasing.

Starting at the front, the Masada-4 uses a metal outer barrel fitted with a flash hider and a 14mm counter-clockwise thread. This allows compatible suppressors, tracer units and other muzzle devices to be installed once the standard flash hider is removed. A dummy gas tube adds visual detail beneath the upper assembly, giving the rifle a more convincing modern military profile. The longer front end suits the designated marksman rifle style nicely and provides a steady sighting platform when firing from a supported position.

The handguard is made from polymer, helping prevent the front of the rifle from becoming excessively heavy. It gives the support hand a broad, comfortable gripping area and complements the more solid metal construction of the upper receiver. Across the top sits a continuous metal 20mm rail, providing generous space for a red dot sight, magnified optic, scope or additional aiming accessories. For a DMR-style build, a low-power scope or compact magnifier would suit the rifle particularly well without making the setup feel overburdened.

The metal upper receiver gives the A&K Masada-4 much of its weight and rigidity. It feels more substantial than an all-polymer airsoft gun and provides a strong mounting base for optics. The lower receiver is manufactured from polymer and features moulded shooting-mode markings along with a textured, non-slip pistol grip. This combination keeps the rifle manageable while still delivering the solid feel many players want from a larger AEG platform.

At the rear, the polymer PRS-style stock is one of the standout features. It includes an adjustable cheek rest, allowing the shooting position to be tuned around the height of your chosen optic. This is particularly useful on a DMR-style rifle, where a consistent cheek weld can make aiming more comfortable during longer games. The rubber-coated butt pad helps the stock sit securely against the shoulder, while the overall shape gives the rifle a planted and deliberate feel when firing from standing, kneeling or prone positions.

The Masada-4 is supplied with metal flip-up iron sights for players who prefer to run the rifle without an optic or keep a backup sighting system in place. The rear sight can be adjusted vertically and horizontally, allowing the sight picture to be fine-tuned. A metal charging handle operates the dummy bolt carrier, and pulling it rearwards allows the bolt to be locked open. This gives easier access to the hop-up area while also adding a satisfying mechanical touch to the rifle's handling.

Controls are laid out for ambidextrous use, including the fire selector, magazine release and bolt release. This makes the rifle more accommodating for left-handed players and allows controls to be reached from either side. However, on this repaired example, one of the fire selectors does not stay in position correctly. The remaining selector should still be treated as the primary control, and the rifle is being listed with this fault clearly disclosed rather than hidden behind vague wording.

Internally, the rifle uses a metal gearbox and has been fitted with a new M100 spring. It has also been rewired to Deans connectors, offering a more secure electrical connection than the older mini-Tamiya style commonly found in standard AEGs. The rifle is supplied with a high-capacity magazine, making it practical for longer games where frequent magazine changes are not always convenient. As a repaired airsoft rifle, it offers an affordable route into a larger Masada-style platform for players who are comfortable buying a rifle with a known selector issue.

Overall, the A&K Masada-4 is a distinctive long-form AEG with a strong DMR appearance, useful ambidextrous controls and a highly adjustable rear stock. The combination of a metal upper receiver, 20mm optics rail, threaded outer barrel and PRS-style stock gives it plenty of potential as a woodland or medium-range build. The new M100 spring and Deans rewire are worthwhile internal updates, while the selector fault is reflected in its repaired-rifle status. It is not a pristine, untouched retail example, but for the right player it provides a solid project-ready airsoft gun with plenty of practical features already in place.
