I have been (somewhat irrationally) interested in a little carbine that takes Glock mags for a while now. Researching a bunch of platforms, I decided to stick with a pistol conversion kit, as most rifles in my price range seemed to be plagued with reliability issues. Most conversion kits weren’t much better, and those that seemed to be reliable, suffer from accuracy issues. The FAB-Defence KPOS Scout has a bit better reviews, and when I found a used low millage example, complete with 6 mags, red dot, and Gen 4 G19 for $900 CAD, I jumped at the chance.
It seems to be a well built little unit, with an aluminum top rail and muzzle cage, coupled with a plastic lower and stock assembly. The previous owner topped it with a junky air-soft riser and a Bushnell TRS-25. It does not come with standard back up sights. I’ll shoot it as is for now until I can determine if it deserves a better optic system.
It comes standard with a folding vertical grip that also doubles as a trigger cover. I guess Fab-Defence thinks this is a viable way to allow the user to sling the gun while loaded. After playing with it, it’s not as hoaky as it looks, but I personally wouldn’t fully trust it if you had to sling the gun and take your hands off it. I think it would be best sling only in condition 3. More on that later.
The folding grip extends to fully cover the trigger. The button in the middle of the grip has a twin on the other side and both must be pressed simultaneously to retract it. You can extend it in increments, and with the grip fully extended you can’t get a full firing grip.
Fully retracted, it exposed the trigger.
I prefer to keep it here, as it still gives decent coverage to the trigger but allows a full grip. On the range only, this would likely be the way I would “safe” the gun between drills. It’s pretty quick to open the grip and shoulder the gun this way.
To close the grip you have to press this button.
The vert grip works well to keep your hand away from the muzzle and it works well with the thumb rests that are integral to the picatinny side rails. The only problem with the grip is that it wobbles front to back slightly at the pivot point when open.
The folding stock is sturdy and does not wobble. To close the stock simply press on the button and fold it.
Closed, you can see the simple folding mechanism. It stays closed by friction, and to open the stock you just have to pull it away from the gun until it locks. The recoil pad is rubber.
It comes with one quick detachable swivel. It works well with the old Magpull MS2 sling I have.
Installing the gun into the carbine kit is simple. You slide it into the upper, making sure to engage the frame rails with the mating rails on the stock. Interestingly, it seems to be largely a friction fit system. You can see in the picture below the internal rails, the rubber pad and spring that the trigger guard rests on. Once the gun is in place you have to forcefully push the stock closed on the pistol, locking it in the stock. There is no up or down flex on the system when closed but I can detect very slight rotational movement on the gun if I force it. We shall see how this affects accuracy, but generally movement is a bad thing for accuracy. To remove the gun you have to press the large button and pull the stock open, which requires a bit of force to do.
The ejection port is very large.
Loading the carbine is done by a non-reciprocating AR style charging handle. This handle assembly extends the entire length of the carbine and engages the slide of the Glock just over the muzzle. Pulling it back charges the gun. Right now it requires a lot of force to do but I haven’t lubed it yet, so maybe that will help.
That’s all I have for now. Hopefully I can hit the range on Sunday and see if it works.
