KAC SR-15, Keymod, nylon, mosfet, Black, Cyma Sport, CM.621

Electric airsoft guns. Replica of the KAC SR-15 Keymod [CM.621] Cyma Sport Edition with electronic switching (mosfet/ETU) in black. The CM.6XX series guns are designed primarily for novice shooters who require a well-functioning gun at a reasonable price. They are characterized in particular by a lightweight body made of high-density polymer and reinforced with nylon fiber for extreme strength and toughness. The gun thus appears very robust and sturdy, but is also much lighter than conventional full-metal models, which will be appreciated especially by the youngest shooters. This airsoft replica is also equipped with electronic switching (MOSFET) and a micro switch trigger (ETU), which are usually found in much more expensive models. The entire outer barrel, buffer tube, and various controls are made of metal. In this price range, the QSC system, which allows you to quickly replace the spring without disassembling the gearbox or the gun, is also a welcome feature. The manufacturer Cyma has once again proven that it can respond to the demands of modern solutions even in cheaper model series.

The gun comes from the latest edition, which has a newly designed body with a functional ejection port, bolt handle, and metal imitation bolt. The modern SR-15 type with a plastic Keymod foregrip (10 inches long), a tactical Crane stock (6 positions), an HK416 pistol grip, and KAC folding sights, between which various optics or Red Dots can be attached. A double-sided steel sling swivel between the body and the stock tube is used to attach the sling; the QD sling attachment on the body of the gun is only an imitation. The double-sided controls are also only imitations (dummy Ambidextrous). The metal outer barrel (length 11.5 inches) is fitted with a plastic compensator, which is screwed onto a 14 mm counter-clockwise thread.

The QSC-type metal gearbox is extremely reinforced in the critical front section (atypical tappet plate), which significantly increases its service life even with stronger springs. It contains high-quality 18:1 steel gears, precision 8 mm plain and ball bearings, an M115-level spring, a QSC metal spring guide, a polycarbonate piston, a reinforced cylinder head, and a counterpressure piston head (parts identical to the earlier Blue Edition). The ProWin-style Hop-Up chamber is plastic, one-piece, and rotary. The accurate and precisely polished 6.03 mm inner barrel has no additional unwanted surface treatments that could significantly impair accuracy and grouping. The silicone Hop-Up buckings are PDI style with modern Omega nub.

The replica is equipped with a modern ETU microprocessor control unit with an integrated MOSFET, which is used to switch the guns electronically. This solution ensures a short trigger pull and a very fast response of the entire assembly after the microswitch is activated.

The package includes a plastic barrel cleaning rod and a high-capacity metal magazine for 300 BBs (Hicap). The replica is equipped with a T-Dean connector and is fully ready for use with a modern 7.4V LiPol battery in CQB design. The battery and charger are not included in the package.

What is Cyma Sport Edition?

Forget the old manufacturer's labels such as Blue Edition, High Speed Edition, Limited Edition, etc. The manufacturer has completely switched to a new and more logical division into three product lines: Sport, Standard, and Platinum.

Since 2025, Cyma Sport Edition has undergone several improvements compared to previous versions. The bodies and external parts are now made of higher quality materials. There have also been several improvements to the internal parts, such as new Hop-Up buckings, in some cases even entire chambers, new gearboxes, and load-bearing internal parts.

Cyma Sport Edition is the basic product line of airsoft guns, aimed primarily at novice players and recreational use. It offers affordable electric (AEG) replicas with a simplified design, but still with good reliability and functionality.
