Yo creo que internamente viene mucho mejor según pone, antes venia unos unternos plasticosos malos malos.
Inside there is a reinforced ver.2 gearbox, steel gears are mounted on reinforced 7mm bearings.
The spring guide is reinforced (metal) together with the bearing (note: guides v.3 are used), which makes the spring work easier - 120m / s spring, giving a shot force of about 400 FPS.
Polymer piston has metal teeth and the cylinder was covered with black nickel "SMOKED" on the copper substrate providing perfect smoothness of the surface.
A huge advantage is the silent piston and cylinder head set, made of aluminum and covered with a blue anode, the piston head has bearing.
The way how gearbox is functioning will surprise a user. It is also worth adding that the model is fully compatible with parts and accessories of other manufacturers, which is important for all types of modifications.
The replica has a powerful engine with increased torque equipped with neodymium magnets.
