[Set] F1 Firearms BSF-19B - Black [EMG] + Mini Pistol / Carabine Red-Dot Sight - Black [JJ Airsoft]

Good, compact optic, with excellent controls, good glass quality and nice, clearly visible red dot, even has an auto turn off feature that kicks in in about an hour. Not sure how it will hold under rapid fire, as i am yet to take it to the field, but the construction seems sturdy enough.

Stunning Glock-style pistol with great looks and performance. It’s not ideal for larger hands, as the grip can feel a little small. Perfect for people with smaller hands. Shoots accurately and performs great straight out of the box. Definitely one of my favourites!

Lovely handgun. Very compact and mags from hi cap “combat master” can be used with this pistol. I recommend, and it looks and feels beautiful. Only thing I would say, if your hands are XL or large, it might be bit small for you.

Had this on a Shark full-auto pistol for a while and it worked fine until one day while shooting the glass just flew off. It wasn't damaged or anything just detached from the frame - managed to put it back with superglue and clean any mess on the glass with acetone, hasn't moved since (over 1000 rounds since then). To be fair, I had dropped it a few times before that, and the full auto blow-back on that pistol is quite violent, maybe on a NBB or at leas a semi-auto GBB it would be fine.
Apart from that it is decently build, and I haven't had any other major issues.
Overall quality is not amazing but not bad either - for the price it is decent.
The buttons are easy to access and it even remembers your brightness setting once you turn it off and back on.
The lowest brightness setting is still too bright, but sadly most red dots are like this.
The protective cap is made from clear plastic and if it is clean you can use the sight without removing it. It has an ear at the back for a string, but it is also a zeroing tool.
Comes with mounting plate for a pistol. Just remember to use the shorter set of screws when mounting it to the plate and the longer ones on the rail mount (comes with two sets). The screw that holds the plate to the pistol needs retightning once in a while. As long as it doesn't get too lose it keeps zero.

I've acquired this pistol solely because of it's looks. It has an interesting design. To be honest I was really impressed by the it's overall build quality, the finishes are superb.
The first thing I've done to it out of the box was a good clean of it's internals and just the right amount and type of lube to make it cycle flawlessly. This is because the gun was really greasy, probably for storage on the shelf purposes.

I already got around 500 rounds through it, around 300 without the RMR and the rest with it. Thus my first impressions are really positive. For such a tiny platform, it's really accurate. I've used G&G 0.25G for all my shooting, this being what I generally use in my pistols. I was extremely impressed by the trigger, it's really crisp, tactile and "loud" so to speak. When dry firing you can really hear it both on the 1st press but also after you reset it.
The gun's frame is made out of metal, but surprisingly, it doesn't feel heavier than a regular Glock.

Now, on to the RMR shooting experience, GBB Pistols tend to be affected by their slide weight, and this pistol is no exception, even with 30 degrees Celsius outside, on regular gas, it tend to used slightly more gas, that wouldn't be a problem, but I've noticed that on rare occasions the slide didn't lock after the last round, so, my solution was easy, I've switched to a higher pressure gas to Nimrod Black, which solved the issue and also made the gun cycle faster with the RMR on top.

For now, the only issue I could find is the slight low tolerance between the slide and the frame. It has quite some play, not sure if it affects much of it's accuracy on short distances, and for long shots, I didn't test it because I tend to switch to pistol mainly as an emergency when the primary rouns out of ammo.

To conclude, after 500 rounds and more to come, the run runs and performs exceptionally well, and I really recommend getting one.
