Pistol Caliber Carbines have been around for a while in various configurations as supplementary weapon platforms as a stop gap between an infantry fighting rifle and a sub-machine gun. In the recent years, the concept of Pistol Caliber Carbines (PCC's) have been expanded on and evolved to fill the ever changing requirements of the modern battlefield and operator. The idea of a PCC weapons platform is to offer similar manual of arms, functions, operation, as well as ergonomics to their full size counterparts but in a much more compact and manageable form factor more suitable for Close Quarters Combat, Vehicle Crews, Airmen, and Security Details. What this creates is a weapons system that will be immediately familiar to the operator and is easy to deploy in tight spaces and restrictive environments without compromising in combat effectiveness.

Early adaptations to the AR based Pistol Caliber Carbine was just taking a conversion kit to a standard AR receiver set. While this allowed a standard AR receiver to operate with popular pistol calibers such as the 9mm cartridge, it did nothing to reduce the excess bulk or mass of the weapon. Angstadt Arms approach to the Pistol Caliber Carbine was to completely redesign the weapon system while following the standard AR formula as closely as possible. The resulting firearm is significantly smaller, much lighter weight, but still retains all of the same controls as your typical AR.

The EMG Helios / Angstadt Arms collaboration project takes the same concepts and ideas behind the UDP-9 to create a training platform that mimics the feel and function of the real thing. The Helios UDP-9 utilizes the EMG/Classic Army compatible PCC stick magazines making it incredibly easy to carry more ammo onto the field. Do not let the small stature of the UDP-9 deceive you, this AEG retains the same performance and functionality of a full size AEG, the only difference is you are now lighter and more nimble, giving you the combat advantage in confined spaces.

The Newly improved G3 gearbox developed under collaboration between Matrix and S&T offers the same features found in the G2 series such as a microswitch trigger, improved steel gears, full steel teeth piston, and aluminum cylinder. New to the G3 series gearboxes is an improved QD spring system which makes it even easier to swap to different strength springs without disassembly. The inline MOSFET features over discharge protection and the electric trigger features a magnetic sensor for improved responsiveness.

"Keep in mind that I'm a fairly amateur player, I own and maintain a few airsoft guns so this is from my perspective.

The gun is great, its durable and light because its aluminum all around. It fires fantastic, better than any guns I have ever owned. It shoots pretty good w the included .23g, clocking at 370~fps (.25g at 390~). The polymer grip feels great, its very sturdy and got this texture that grips nicely. The hop up is easily accessible like typical in M4 platforms, and adjustable with the wheel. The charging handle doesn't lock back unfortunately. Ambidextrous fire modes are easy to switch around. The battery compartment is very easy to access, simply by pressing the flushed button and removing the cap on the back of the stock. Speaking of the stock, its not for everyone, but I find it comfortable for myself. It is very slim and designed for mostly for CQ fights. The magazine is straight up plastic, but very light, which can be a good thing for long term travel. However, these are mid caps so they won't hold up many BBs. In fact, loading them are a pain in the rear. There's no quick way to load BBs unless you have a speed loader. Other than that, they feed very well.

The whole rest of the package comes great with the Evike 32" bag that can hold two guns, and enough accessories for them. I can fit nearly everything I needed in the bag. It feels great and the fabric doesn't feel cheap. The batteries included are great too, the charger was able to charge them extremely quick. The package does come with 2 additional mags so its nice that they're included. Finally, the Red Dot, its decent and will get you by.

Brief List
-Gun is impressive w very good ROF and FPS rating. Nearly full aluminum construction from handguard to low profile stock.
-Included Evike Bag, Battery, Extra Mags, Charger, and BBs.
-Battery Space is enough.
-Good top RIS room for most optics.
-10.5" MLOK Handguard has enough room for most accessories.
-Good Trigger Response
-Magazines Feeds Well. Mag release is on the right, and magazine exits easily.

-Magazine feels cheap but not that fragile, kind of hard to load BBs.
-Charging handle doesn't lock.
-There's tiny wiggle room in the mag well.

Overall, its a pretty decent deal if you want everything in one set with a good AEG.
