UAR 501 Assault Rifle Replica - Black

UAR 501 assault rifle replica by APS is an innovative construction equipped with a special hybrid gearbox called "APS Hybrid Gearbox". The abbreviation UAR stands for Urban Assault Rifle, that is a model designed with MOUT (urban combat) and CQB (close quarter combat) character scenarios in mind. Compact design and high manoeuvrability of the rifle were achieved due to its bull-pup construction. The insides contain and efficient, 385 mm outer barrel while the full length of the replica is barely 645 mm.

Practically the entire receiver was made from reinforced polymer. Thick stock pad was made from rubber. The replica features a long, top, RIS 22 mm mounting rail as well as three handguard rails. This allows to mount a wide array of additional attachments on the replica, starting with optical sights, through grips and tactical lighting and ending up with laser sights. 

The replica is incredibly functional - it features three magazine release buttons: one at the magwell and two near the pistol grip - they can be used with an index finger. The fire mode selector is double-sided and the charging handle can also be operated from both sides, which allows for easy operation to both left- and right-handed users. Once the charging handle has been pulled back, the user can access the Hop-Up chamber. The bolt-catch release button is located at the top of the stock.

The battery is stored inside the stock, under the stock pad. The pistol grip is hollow and there is room inside of it for 2 spare 123A batteries. The replica comes with two Hi-Cap magazines with a capacity of up to 190 BBs.

The new V.3 “APS Hybrid” gearbox constitutes the heart of UAR 501 replica. Designed and manufactured in an innovative and most user-friendly way, according to comparative tests conducted by manufacturer it is 33% more effective when it comes to energy consumption than a standard system. It is equipped with a Fast Spring Release system that allows the user to change the muzzle velocity of the replica without having to open up the gearbox. The set includes 2 main springs: one allows to achieve a muzzle velocity of ~320 FPS, the other ~350 FPS.

Reinforced gears were mounted on 7mm, metal bearings. The electric system consists of a silver-plated, low-resistance wiring that provides stable operation of the circuit, while the replica’s motor has a metal core. The cylinder and semi-precision internal barrel with a diameter of 6.05 mm were made from stainless steel

A reasonable for an assault rifle replica muzzle velocity of ~350 FPS  together with an optimal internal barrel length and a decreased diameter make this replica ideal for assault operations and medium- and close-ranged combat with high efficiency and focus. 

The set includes:

- replica
- 2 magazines
- additional main spring
- cleaning rod
- manual

Velocity [FPS]:

It is the spped of bb, while its leaving the innerbarrel of replica. This speed is measured in FPS (Feet Per Second).

1 FPS = 0,3 m/s

1 J = 99 m/s

1 J = 326,7 FPS

Propulsion / Powered by:
Gearbox version:

Indications v2, v3, v6 does not mean the level of advance, but only shape of gearbox skeleton which was used and selected by the manufacturer depending on the capabilities of the body of the replica. For example, a models of the M4/M16 family, MP5, have a v2 gearbox, while the AK family have gearbox v3.

APS Hybrid Gearbox
Type of fire:
Single, auto
Diameter of bearings in GB [mm]:
Lenght [mm]:

The length of the replca is measured between the two most distant points of each other. Different models have several of these values, because of its design allows to increase or decrease it length (eg.  folding stock or extended flash hider).

Inner barrel length [mm]:
Weight [g]:

This is a value that includes the weight of the replica, magazine and other accessories that are include in set without a battery, charger, cleaning rod, etc., etc.

Magazine type:
Hi-Cap magazine
Magazine capacity [pcs]:

Hop-Up system is used for overclocking bb during the shot (putting it in rotation), through which, it extends its flight path. Acting laws of physics make that bb lift up, while the gravitational force take it down. Appropriate adjustment of Hop-Up, will compensate for these two factors, which result in long and straight flight for longer distance and be greater focus shot (to improve accuracy).

Yes, adjustable
Blow Back:

Blow back is a simulation system of the cocking lever - it imitates the work of it as the equivalent sharp. This system raises the realism and adds a lot more experience during shooting.

Battery included:

NiCd rechargeable battery is characterized by high efficiency current-carrying capacity, but there are disruptive effect on memory. Should be unloaded and loaded in the full cycle, ie, it is recommended to fully discharge, and after unloading must charge the battery immediately without leaving it for a long time in a discharged state.
NiMH batteries have a higher self-discharge over time and shorten the life - on the other hand, they earn about 30% more capacity.

Below are my opinions after refitting the rifle and my first game with this beauty: Pros: Great weight balancing due to the back mounted gearbox Relatively light Easy to move around with it, doesn't hinder movement After general refit it has decent accuracy Easy disassembly Cons: The cilinder was shorter than it should have been, it needed an immediate replacement. Upper front battery containment had no wiring, needed to lead the wires from the back of the rifle. The weapon fire mode selector is a bit tricky Some may say the gearbox is too close to the shooters ear and is too loud. (Personally love it) Although it's said that it gets along well with M4/M16 magazines, after trying 3-4 aforementioned types, it still gets along only with the factory shipped magazines (without modifying the other magazines)

Pros: -fires 328 fps out the box on 0.2g bb's, comes with an M120 spare -strips down in seconds via 3 pins, make sure you read the instructions though, you must do this in semi or it will cause problems! -completely ambidextrous -comes with 2, 190rnd high caps -QC spring gearbox is easily accessible -build quality is fantastic, plenty of rail space (these are true picatinny spec so chinese clone items don't seem to fit too well ! ) -gearbox comes with low resistance wire as standard cons: -these now come rear wired with a "larger" battery space in the stock - not true, you can't even fit an 8.4V NiMH in it, i'd relocate it back to the front and use a stick 8.4v or 9.6v - if you're a LiPo user then no problems -still VERY fussy with mags, but the APS ones are fantastic quality so you can just order a couple extra (not even that expensive) -very long trigger pull unfortunately, you may be able to adjust this by doing some modifications internally and it's very accessible -no ironsights as standard extras: -14mm ccw thread is hidden under a huge flash suppressor, don't worry it is there and this one doesn't seem to have the super glue on it as per the gen 1 versions - worth mentioning the flash suppressor itself has a CW thread hidden in the front of it, no idea why though -has room for 2 CR123 batteries in the pistol grip so far i'd say the quality and performance is fantastic, rare to get a gun exactly as described!

Very solid AEG; Bullpop configuration is great for CQB or fast action games. Full length barrel assures a good accuracy. The polymer is strong enough to take hard punishment during woodland matches. It can take M4 magazines, though there are some compatibility issues. Field strip is fast and removing the gearbox can be done with removing only one screw which can be great when you need to switch it out in case of a problem. Also, the QD spring system assures that you can be ready for any FPS limit within minutes.
