It’s that time again, another Mystery Box unboxing for the Replica Airguns channel. As usual, no idea what’s inside going in, but this one lines up right after SHOT Show season, which usually means some interesting gear starts showing up.
This isn’t a full review, just a first look at what came in. Detailed Table Top and Field Test videos will follow once everything gets properly looked at and tested.
What’s in the Box?
This month’s box included three very different airsoft products:
It also came with a barrel extension, but it arrived with damaged threads. Not a huge loss since those extensions tend to be fragile anyway and aren’t essential for most users.
Takeaway: If you're looking for a Glock-style platform without licensing restrictions, this fits the role well. Likely compatible with some Glock holsters depending on fit.
Battery-powered box magazine with hopper feed system
Integrated bipod and carry handle
Multiple Picatinny rails
Includes extra spring and accessories
The feeding system and internal layout aren’t immediately obvious, it’s one of those guns that clearly requires some setup and understanding before use.
Takeaway: This is not a casual backyard plinker. It’s a full-on support weapon platform, something you’d expect in a tactical or milsim environment.
A much more approachable and practical option compared to the F249.
First Impressions:
AR-style AEG platform
Mostly polymer construction with some metal components
Adjustable stock (buffer tube style)
Picatinny rails and M-LOK compatibility
Comes with both orange and black flash hiders
Includes extra spring (M90) for velocity tuning
Dean’s connector
Takeaway: This looks like an entry-level to mid-tier rifle, compact, lightweight, and ideal for someone getting into Airsoft or wanting a versatile CQB setup.
Overall Thoughts
This box had a good mix:
Pistol platform (KP-13) → familiar, practical
Entry-level rifle (SA-F04) → accessible and versatile
Heavy support weapon (SA-F249) → niche, but very cool
The F249 clearly stole the show just based on size and complexity, but the SA-F04 is probably the one most people would actually use regularly.
What’s Next?
As usual:
Tabletop reviews will come first (closer look, specs, handling)
Field test shooting videos are stacking up and coming next
Where to Find These
If you're in Canada, these should be available through:
Type: GBB Airsoft Pistol. Manufacturer: Cybergun Model:FN Herstal FNX-45 Tactical. Materials: Metal and polymer construction. Weight: 1.8 Pound (820 grams). Barrel Length: 4.8 inch (12.2 cm). Total Length: 8.9 Inches (22.6 cm). Propulsion: Green gas or propane Action: Single and double action. Ammunition Type: 6mm plastic Airsoft BB’s. Ammunition Capacity: 25 round magazine. Max FPS: 380 fps.
Trigger Pull: The Cybergun FN Herstal FNX-45 Tactical GBB Airsoft Pistol has a single and double action trigger setup. Both feel pretty good with a surprisingly light double action trigger pull, the blowback action will cock the hammer between shots allowing for the vast majority of your shots being single action which you will find are short and very light. There is a little bit of take-up followed by a crisp light release.
Accuracy: So far I have not made my Field Test Shooting Video for the Cybergun FN Herstal FNX-45 Tactical GBB Airsoft Pistol. Keep posted for my upcoming Field Test Shooting Video for the Cybergun FN Herstal FNX-45 Threaded Barrel GBB Airsoft Pistol, until then I can not really comment on the shooting results.
Build Quality: The build quality of the Cybergun FN Herstal FNX-45 Tactical GBB Airsoft Pistol feels really good, it has a nice weight to it and feels really solid in the hand. The materials used look good and have an excellent finish to them. There is just a bit of a slide wiggle but not excessive. You will find metal parts where you would expect them to be like in the slide, barrel components, magazine, slide catch release, take-down leaver, hammer and lots of internal parts.
Realism: In terms of realism the Cybergun FN Herstal FNX-45 Tactical GBB Airsoft Pistol is pretty much the spitting image of the real steel version with all the markings and licensing in all the right places. Mechanically everything works about the same including full field strip-ability with full ambidextrous controls.
Pros:
Build quality feels really good.
Full length blowback action.
Accurate licensed TFN Herstal FNX-45 Tactical replica.
Trigger pull is nice in both single and double action.
Picatinny rail for adding accessories like a tac light or laser.
Double stack full size drop out metal magazine holds the gas and 25 Airsoft BB’s
Comes with additional back-strap in smaller size for smaller hands.
White dot high rise front and back sights suitable for compensators.
Fully ambidextrous controls.
Easily Filed Strippable.
Tip is easy to remove for addition of a mock compensator.
Adjustable Bax Hop-up
Cons:
Sights are not adjustable.
Just a little bit of slide wiggle.
Comments: The Cybergun FN Herstal FNX-45 Tactical GBB Airsoft Pistol is a really great looking gun. The quality is on par with KWA and KJ Works in my opinion. I’m not sure who actually makes it as Cybergun is the license holder and distributer but I feel like the Cybergun FN Herstal FNX-45 Tactical GBB Airsoft Pistol is a step up from the standard KWC gun often used as the base. I look forward to testing out the Cybergun FN Herstal FNX-45 Tactical GBB Airsoft Pistol in the Sea Can indoor Airgun Shooting range to see how it performs. I’ll be testing with the short barrel and with the barrel extension installed to see what the fps difference is between the two.
My Vimeo Table Top Review for the Cybergun FN Herstal FNX-45 Tactical GBB Airsoft Pistol:
In this Table Top Preview video I take a look at two Blowback Airsoft Pistols one Distributed by Cybergun and the otters Distributed by ASG. Both are very similar in that they have threaded barrels which makes them much suppressor ready the big difference being that the ASG CZ P-09 is CO2 powered while the FN Herstal FNX-45 is Green Gas or Propane powered. IN this video I talk about the specifications and details and also show both Airsoft Pistols up nice and close.
