VFC VR16 Saber CQB AEG Review

VFC recently updated the VR16 line of AEGs and added a few new models to the line-up. The VR16 Saber QCB is a welcomed addition to the VR16 family and yes, this one looks exactly like the KAC 300 BLK rifle. Its most prominent feature: the 8″ KAC URX 3 frontset.


VFC’s VR16 series has been on the market for quite a while now and this year, VFC has completely updated the gearbox and added a new stock called the “QRS Stock” to some of their models.



At first, let’s get a quick overview of the AEG. I mean, what can I say, it’s just another M4, isn’t it? It features an aluminum receiver in known VFC qauality, an aluminum URX 3 style frontset, a Surefire SFMB-556 style flashhider, polymer flip-up sights and the QRS stock, made out of polymer too.


The first thing that comes to your mind when unpacking the VR16 Saber CQB is: THIS THING IS LIGHT! I even thought it had a polymer body, I couldn’t really believe, that the AEG would be so light with a metal receiver. The Saber CQB weighs about 2.5kg, wich is way lighter than what I’m used to – full-steel AKs mainly.

Sadly, when inspecting the AEG, there’s one thing that dampens the initial euphoria a little bit. The QRS stock wobbles like crazy. I mean, I appreciate it, when companies try to create something new and innovative, but the feeling of the polymer and the wobble creates an immediate “that’s crap!” feeling. I mean, VFC is producing all the parts by itself, why not make the stock a tad tighter to fit the stock tube better? I’ve seen better, VFC!



The Receiver

The quality of the receiver is as good as one would expect from VFC. The surface is even, the paint/coating is sturdy, the engravings are not that sharp but what I really like is, that VFC declares the caliber as 5.95mm and not 6mm as most other companies do. 5.95mm is the exact caliber of the BBs we use.



The Frontset

The Saber CQB’s frontset is a clone of the KAC URX 3 8″ rail system. Biggest difference: the VFC rail is a one-piece design and screws onto it’s barrel nut where as the KAC URX has a two-piece deisgn and uses a way different barrel nut.


The flash hider is a clone of the Surefire SFMB-556 and adds a sporty look to the carbine. The URX rail features short pieces of picatinny rails on the front so you can mount your favorite flashlights, lasers, grips etc.


In the middle section of the rail system are your three URX mounting holes. Sadly, the URX system isn’t as widely spread as the Keymod system and accessories are quite scarce.

At the rear end of the rail system, on the 3 and 9 o’clock position are two QD mounts for your sling.


The frontset is held in place by just two setscrews. A quite minimal construction, could have been made a litte bit more solid in my opinion.


The outer barrel has a two-piece design wich is causing the outer barrel to wobble just a tiny bit. The front part of the outer barrel is mounted with 2 small set screws and this creates some sort of pivot point as the rear end of the front part of the outer barrel has minimal play inside the back part.

By using a one-piece design the wobbling could have been avoided but I guess this has some sort of production benefits, as the outer barrel and the front set can be changed quickly.

You can use a small piece of teflon tape to fix the wobbling. Just wrap around a small piece and push the outer barrel in, this will stabilize the pivoting.



The Stock

The so called “QRS” stock is a new product and it somehow reminds me of the STS Sopmod stock from IMI Defence. The QRS stock has two QD mounts an the lower back end, a traditional sling mount on top, a short picatinny rail on the bottom for mounting various accessories and the ability to remove the side pods, wich can accomodate a nunchak-type battery.

As I mentioned before, the stock wobbles heavily and I’d switch to another stock as soon as possible, because there’s nothing more annoying than a wobbling stock.

The buttplate can be removed and folds upwards easily to store your battery. It holds a wide variety of batteries. I had used a 3-cell stick-type 11.1v 1300mAh LiPo as well as a 2-cell 7.4v 1450mAh nunchak-type LiPo without any problems.


If you’re a fan of one-point slings, there’s a sling plate on the backside if the receiver.



The Flip-Up Sights and Hop-Up Chamber

Flip-up sights. They look nice on the gun but feel very fragile and cheap. They’re made out of polymer and fold up by them selfs when the button is pushed. A bit of a downer: you can’t just push the sights back down, no, you have to push the button again to allow the sights to fold.

The boltcatch workes and holds the fake bolt back when pulling the charging handle back. It’s a nice feature and adds to the realism a bit.


Something I really like is the one-piece hopup design with its rotating adjustment wheel. It’s a far better design then the standard M16 hop-up, it’s more failsafe and can be adjusted way better.



The Hearth of the VR16 Saber: the Gearbox

Let’s take a look at the one thing that is completely new: the gearbox. VFC has updated it’s previous version of the gearbox and put in some fine parts.

At first, we have to disassemble the receiver and remove the gearbox. This is quite easy: push out the two receiver pins, remove the bolt release, unscrew the mag catch, remove the motor and grip, remove the pin above the trigger and you’re done.


The motor has no label at all and looks quite unspectacular – it’s a high speed type though.


Ok, here it is: the new VFC V2 custom gearbox. Well, the only thing custom here is the bolt catch on the right side to be honest.


I have to admit, I hate V2 gearboxes. I really do. But this one has some fine features wich makes me hate it way less. Usually, when disassembling a V2 gearbox you have to be careful and hold the spring guide in place when removing one half of the shell otherwise the it will jump right out of the gearbox when opening the shell.

Not with this VFC gearbox. VFC added a screw to mount the spring guide to the shell and this prevents the piston from jumping out, it stays in place securely. Very well done VFC!


The trigger and anti-reversal latch do also stay in place securely. Something I appreciate very much and means, that the tolerances are very small.


The internals are top notch: a polycarbonate piston with 14 teeth and a steel insert, a aluminum piston head, a stainless steel cylinder, polycarbonate cylinder head and air-seal nozzle. The high-speed gears look and feel quite strong and sturdy.

With such internals out of the box, no tuning is needed for quite some time i think.


8mm bearings assist the high speed gears.


Nice to have: a delayer chip on the sector gear wich helps pulling back of the tappet plate a bit sooner to prevent feeding issues on high-speed setups.


Eine wirklich tolle Gearbox, die VFC der VR16 Reihe spendiert hat. In meinen Augen kann man das als Complete-Tuning-Gearbox  durchgehen lassen.

A very, very fine gearbox for such a low-priced AEG. I’d say this gearbox is as good as any complete aftermarket tuning-gearbox.

With it’s update of the VR16 family, VFC offers a comparable cheap AR series with internal parts, that make a lot of the pro-line guns out there look like sportsline variants. For 246 USD you’ll get an affordable, solid and very well performing AEG in known VFC Quality. Only the wobble of the stock is a little downer.

If you are looking for a base gun for your next AR build – give the VR16 family a try.
