G39C IDZ GBB Open Bolt (AWSS Version) Airsoft -F-

G39C IdZ GBB Open Bolt Airsoft by WE The advantage of the Open Bolt principle is the significantly lower tendency to experience the Cool Down effect, as there is no brass cylinder installed, which can freeze at high rates of fire. Thus, the G39 can reliably perform its duty even at lower temperatures. The housing is made entirely of glass fiber reinforced plastic and is very stable. It gives an extremely robust impression. The light texture of the surface is very well modeled after the original, and the markings for the fire modes are applied very cleanly. The stock can be folded down if needed and locks securely and without play. Additionally, the stock can be adjusted in length in 5 stages. The soft rubber stock cap ensures a firm and secure shoulder position and dampens the recoil, which is almost comparable to the original. The top rail features a fully adjustable rear sight in height and side, while the front sight is fixed. Various optics can be easily mounted on the upper rail using a Weaver mount. Just like the real counterpart, the WE G39 can also be disassembled into its main components without tools (though initially, you may need something to tap it as the pins are very tight). This makes maintenance and care tasks significantly easier. The removable handguard is equipped with three Weaver rails and conceals the one-piece outer barrel made of aluminum. The gas intake has been excellently replicated and, in conjunction with the aluminum-made flash hider, conveys an extremely high-quality impression. The bolt of the G39 is made of metal, and due to its relatively high weight, the felt recoil is one of the strongest we have experienced so far in a GBB rifle. The G39 is suitable for both left- and right-handed shooters, as controls such as the fire selector lever and charging handle are present on both sides. Beneath the charging handle is the easily accessible hop-up, which can be adjusted very precisely. As with all WE models, authenticity was also prioritized here, as the bolt remains in the rear position once the magazine is empty. The gas magazine holds 30 rounds and is equipped with the typical tabs that allow the magazines to be coupled together. Unlike the M4 and PDW magazines, no dry fire function can be set here. However, it is possible to fire the weapon without BBs by pressing the bolt catch button intended for the original G36, located above the trigger. Unfortunately, the magazine's appearance is not quite as successful, but there is a great thread in the WE forum on how to enhance its look ;-) http://forum.weairsoft.de/index.php?page=Thread&threadID=1322 Shooting test: The propellant gas of the weapon is located in the magazine. We conducted a shooting test to determine the pressure drop when firing 30 BBs. We used 0.20g BBs and green gas for the test. This resulted in an energy of 1.41 Joules for the first shot and 1.08 Joules for the last (30th) shot. Thus, the weapon has an energy drop of 0.33 Joules, which we believe is quite acceptable.
