Replica Airguns May Mystery Box Unboxing – What Showed Up This Time?

No Comments

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:

1. KJ Works KP-13 CO2 Airsoft Pistol

A Glock-style pistol - but not a Glock.

First Impressions:

  • Very familiar Glock-like ergonomics and controls

  • Polymer frame with a metal slide

  • Trigger safety and integrated accessory rail

  • Front fiber optic sight, black rear sight

  • Full-size drop-out magazine (CO2 powered)

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.

2. Specna Arms SA-F249 Machine Gun (ParaFlex)

This was the standout item, and easily the most unexpected.

First Impressions:

  • Large, heavy, and very aggressive-looking

  • FN M249-style light machine gun “replica” (Non trademarked)

  • 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.

3. Specna Arms SA-F04 FLEX Electric Airsoft Rifle (Gen 2)

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
