Specna Arms SA-FX01 FLEX™ HAL ETU™ - Half Tan

The name HAL is derived from the principle of the so-called Hall effect, by which the unit senses the sensitivity of the trigger.

Specna Arms Flex

Are you starting out with airsoft and looking for a cheap but quality gun to get you started? Or are you just looking for a lightweight gun for your child for camp or airsoft club? Then you should be interested in this new Flex series from Specna Arms. That's because Specna has decided to dress up the Core line in a new all-polymer jacket that has kept the price of replicas to a minimum. The new guns come with a polymer foregrip, which also significantly reduced the weight of the replica itself, making the Flex series an ideal buy for kids who want a nice rifle but don't have the strength to run around all day in the woods with an all-metal replica. 

You don't have to worry about the gun being fragile and not being able to withstand anything. On the contrary, polymer is flexible and very durable. All of the functional parts inside the gun such as the mechabox itself, the wheels, piston gears, etc. are metal just like the Core series. The outer barrel also remains metal. 

The gun has the option of the QD ESA system, which means you no longer have to remove the mechabox from the barrel to change the spring. So you can change the spring through the tube right in the field. The gun can easily handle 7.4V or 11.1V LI-Po batteries, but we recommend using 7.4V in the base for longer life.

Batteries are inserted into Light Ops type stocks, so care must be taken to ensure that the battery you choose fits the stock.
