ARP 9 2.0, Electronic trigger

Modern weapon UDP-9 (Ultimate Defense Pistol) was developed by the american company Angstadt Arms and as a flagship is currently deployed in over 30 countries worldwide. The Angstadt Arms UDP-9 is a lightweight, compact AR-15 style firearm chambered in 9mm and fed with double stack GLOCK magazines. It meets the PDW (Personal Defence Weapon) parameters - it is compact and lightweight, ideal for fighting in buildings.

G&G ARP-9 is an UDP-9 airsoft replica. It is a very well made weapon, perfectly suited to the CQB.

The body of the weapon, including retractable stock, is made of durable polymer with a nice finish. The controls are the same as the M4 thanks the AR-15 platform. There are selector switch (pleasantly accurate) on the left side, ambi charging handle and shell ejection window on the right side - the access to the plastic high-quality hop-up chamber. Hop-up is adjusted using a rotary ring.

A special feature of this weapon is the magazine and its magazine catch, which is the same style as the AK - under the magazine shaft. The real weapon uses Glock magazines. The airsoft version imitates these magazines, but of course not it isn't possible to use a Glock gas magazine. The package includes a long hi-cap mag. You can choose other variants of hi-cap or low-cap magazines. See Related products below.

Version 2.0 has a larger battery compartment compared to the previous version and a new stock design. The PDW style stock features a quick deployment feature as well as adjustable length. The entire length of the stock can be adjusted, allowing you to find the perfect setup for everyone.

The stock is attached to the body using 2 strong metal rods. There is a plastic tip at the end of the stock tube, secured by a button. Under the tip is wiring with a mosfet, fuse and gap for battery. We recommend a compact 7.4V Li-Po battery see Related products. The space in the stock is approx. 3 x 2,5 x 14 cm.

The handguard is made of metal with M-LOK mounting standard. On the upper side is located classic RIS rail with removable metal sights (laterally and height adjustable). The flash hider is wide and short and works more like a sound amplifier - the shot is really loud and certainly many enemies will surprise.

And how does it look inside? You will find there a reinforced gearbox with a blue cylinder and 8 mm bearings, the ETU unit, a piston with a first metal tooth and a torque-up gear set with the G&G engine. Hop-up chamber is plastic with rotary ring. The barrel length is 168 mm, we have measured the muzzle velocity of 125 m/s.

Bottom line, a very good "balanced" weapon - in size and look, as well as internal components. Just CQB ready.
