Airsoft rifle M4 SD Sportline 7" Alpha stock BI-TON (Gen.2) - BK-TAN

This Lancer Tactical M4 is, due to its low weight and price, especially suited to beginner players, but it will also be appreciated by the more experienced players due to its quality and performance.

Gun is equiped with new Alpha stock. Uunique design, which is made of lightweight yet durable polymer. It offers new opportunities. Notice the M4 magazine well, which means a possibility of a magazine ready to quick change. Altough it doesn't look so, the stock has adjustable length - four positions. And of course, the stock is of a well-designed ergonomic shape. There is a quick detachment sling mount on the left and the right. This Apha stock support storage of the twin CQB battery. Half is inserted into the stock under the tube and the other into the stock tube. See photos in the gallery.

At the end of the barrel is a silencer, which begins in the RIS forearm. In this case, the Socom type silencer is not only cool design, but also hides the inner barrel. It is well axially guided and is therefore about 39 cm long.

In the package, you find two magazines. One long classic AR-15 look. It is plastic, capacity 120BBs. The second, inserted in the stock magwell, has a modern look with a capacity of 70 rounds. We suggest to buy BBs quick loader. See accessories bellow. Gun is capacity with the common M4 magazines.

Quick spring change system

The gearbox and the replica body have QSC system - spring change takes few minutes. The QSC system (the quick spring change system), means that the spring guide can be removed from the gearbox without removing the gearbox from the body. There are locks on the head of the spring guide and the holes in the gearbox. By turning the spring guide, the spring guide and spring can be removed. This weapon has also a QSC system on the body - no need to remove the gearbox from the body - just remove the stock and unscrew the stock tube.

Cylinder and piston

The cylinder is polished for smooth piston action and increased performance.
The piston has a metal tooth for maximum durability with stronger springs. The piston head is plastic with rubber compound, for a softer and lighter stop and longer life.

Gears

Metal gears have a straight tooth that reduces axial forces. The piston gear is equiped with a BB supply cam for smooth BBs supply from magazine, even on high rate of fire.
