Cyma CM503 M4 Carbine Replica in Blue


The CYMA Family of Airsoft replicas is the perfect choice for airsoft players seeking good quality products at a reasonable price. The principal factor that allows them to reduce costs is using high-quality plastics instead of metal for parts (for example, the weapon's body) in the manufacturing process.


But at the same time, keeping a metal gearbox that provides around 400FPS of heavy-duty shooting power and the other good quality mechanical parts inside the rifle make this CYMA replica as effective on the airsoft battleground as some of its more costly counterparts.


Just moments after taking the replica out of the box, you will notice a very precise fitting of the gun's elements as there are no loose parts or gaps, even in some of the key places such as the gun stock or front end/front grip that can be present in many other airsoft replicas.


This CYMA replica includes a set of the most necessary accessories such as the battery, charger and sling. The weapon is ready for action out of the box.


Most of this gun's core components are made from rigid plastics, such as the front grip, stock and sights.


The outer barrel is made of Alu, while the magazine's case and safety switch are made from steel.


Despite the usage of plastics, the shooter will not notice any obnoxious creaking of the body, which can be present in most cheap replicas.


cm503 features a removable top carry handle that fits on the universal 22mm RIS mounting rail.


It also allows for attaching an extensive range of telescopic sights etc. The replica also features an adjustable collapsing stock with an anti-slip butt that has several different positions to enable it to fit most users in comfort. At its end, the outer barrel has a 14mm left-handed thread that permits it to mount a suppressor.


Access to the hop-up adjustment system is standard (when you retract the cooking handle. Safety the fire selector is located on the left-hand side of the body.) At the core of this airsoft replica is a reliable, v.2 type metal gearbox with a set of steel gears, warped spring guide and 7mm bearings That enables for more or less 410 FPS muzzle velocity straight out of the box.


Shots fired from this CYMA rifle are precise and deadly accurate with a long-range due to the 360mm long inner barrel.


The replica includes a 300 round hi-cap magazine made from steel and plastics. This models battery is located inside the heat guard at the front of the bb gun.


All those features make cyma airsoft guns the perfect replica for those just starting to play airsoft. But want a skirmish ready rifle, so If you're looking for a solid m4 with good internals, high muzzle velocity, beautiful looks and all complete set of accessories, then Spartan is just for you.
