M4 SA-F01 FLEX BLACK SPECNA ARMS RIFLE (SA-F01-BK)

The airsoft replicas of the FLEX ™ line are characterized by an attractive price combined with an innovative spring replacement system and high quality materials
Nylon fiber-reinforced polymer is used for the barrel, floating front, slide and enlarged SF stock, as well as for the pistol grip. Aluminum alloy and ZnAl were used for the barrel, flame suppressor, enlarged reload handle and manipulators. All the screws, the pins, the cartridge ejection window and the dummy lock are made of steel. Markings and serial number have been applied to the body.
The replica has been fitted very well, the user will not notice any play between the lower and upper body. The use of the lightweight body and front made it possible to reduce weight, making it perfect as a replica for CQB's dynamic games. In addition, the nylon fiber reinforcement makes the construction more durable than other polymer constructions.
