ARP 556, Full metal, Electronic trigger, Black

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 with classic M4 magazines unlike the real gun. It is a very well made weapon, perfectly suited to the CQB.

The body of the weapon is made of metal (Intermediate serie) The retractable stock is made of durable polymer with a nice finish. The controls are the same as the M4 thanks the AR-15 platform. The ambi selector switch on the sides, the ambi charging handle on the top 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.

The magazine is hip-cap 450 BBs. You can choose other variants of hi-cap or low-cap magazines. See Related products below.

The stock is attached to the body using 2 strong metal rods. It can be secured in two positions - retracted and extended (by 9 cm). 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 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 8mm bearings, the ETU unit, a piston with a first metal tooth and a torque-up gear set with the G&G IFRIT 25K High Torque engine. Hop-up chamber is plastic with rotary ring. The barrel is, due to the length of the gun itself, short - 128mm, we have measured the muzzle velocity of 120 m/s.

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