| Systema expands their P.T.W. range with this TW5-A4, which marks a change from their range of M4/M16 P.T.W.s. Obviously, the Systema quality still remains and they have even improved the durability of the product even more.
This TW5-A4 features a one-piece die-cut metal body that has been produced to realize an unimaginable levels of strength and durability. Like the other guns in the Systema P.T.W. range, the TW5-A4 replicates the dimensions of the real steel equivalent; the main receiver has the same dimensions of the real one, thus parts used with the real steel, such as a scope mount, can be used with no hassles. Even with parts such as the grip frame, share the same dimensions as the real one. All this helps to make this a premier training tool of choice.
The control unit is adopted from the previous gearbox system, although has improved performance, able to endure a higher temperature generated thus making it even more reliable than before. The computer also allows the TW5 to operate in semi auto, 3-burst auto and full auto modes. Note that this is the first one on the airsoft market with 3-burst mode! The motor utilizes a steel magnet case and an exclusive TW5-specific 480 type motor. The PTW5-A4 MAX will come standard with the M1500 Spring Cylinder Unit.
Like the previous M16 series, this TW5 maintains an interval dimension, between the outer and inner barrel of only ±0.05mm; the outer barrel is produced using Systema's method of metal shaving. The inner barrel incorporates an internal diameter of 6.04mm.
Systema recommend using a 9.6v 2400mAh battery, the stock is plenty of room to store a large battery and the maximum sized battery that can be used is a 12v 2400mAh battery. Battery not included.
