ASG H-22 STC Hybrid GBB rifle with HERA Arms chassis, 427 FPS, TDC hop-up, 29-round mag, and RogueWorx customization.
The H-22 STC brings a real‑steel tactical feel to airsoft with a HERA Arms chassis built on the proven KC‑02 / Special Teams Carbine platform. Designed for players who want realism and modularity, the H‑22 STC ships with a full Picatinny top rail, M‑rail mounting points and an EVO carbine flash hider so you can kit it out for every CQB or field role.
Performance is driven by a reliable Gas Blow Back system that delivers authentic recoil impulse and consistent operation with ASG‑compatible gas magazines; a CO₂ magazine option is commonly available for higher power or different weather conditions. The TDC adjustable hop‑up and a 14mm CCW threaded outer barrel let you quickly tune groups and add suppressors or tracer units as needed.
Comfort and ergonomics are front of mind — the HERA buttstock includes a removable cheek riser, rubberised butt pad and side panels for a tailored fit, while a stock spacer adjusts length of pull. The metal handguard and RogueWorx compatibility make this platform ideal for players who plan to customise with high‑end aftermarket parts.
Whether you’re a kit‑fat player who demands looks and function or a serious marksman wanting a stable GBBR platform, the H‑22 STC balances precision, modularity and field‑ready durability in a single package.

Very good quality and services 👌 Thank you
Great value
Cold Steel 92FK FGX Kerambit-fixed Blade Knife.
Was sceptical at first, being a plastic knife and all.
Now I love it! It has a purpose and is not ambiguous about it at all!
A great way to experience the Kerambit before committing to the "Real Deal"
Very good and fast to be delivered
Received my fragrance! Very happy and would definitely buy again from this shop
Doing fine with the inverter

Kind regards Dawie
Great product
Very consistent cycling whitout any issues
This AKSA AK21 is an incredible replica. Initially, I struggled hard with it—every attempt to chamber a round resulted in a severe Failure to Feed (FTF). I hadn't even fired a shot yet and was ready to pack it up for a return. After discovering it just needs to be aggressively snap loaded, it feeds perfectly. Definitely recommend
Best price anywhere on the internet. Speedy delivery
Quality products and excellent turn around time.
I received my Ekol f92 in 4 day and it fill like a real gun
At first i thought it was a scam because of the review I saw on Google reviews. But it turns out people who are getting the worst experiences are not from the gun sector. This company knows how to keep its customers happy.
The quality of the gun, the looks of the gun the feel of the gun is very appealing. But I am a bit disappointed with the oil of the gun because the gun already came already oiled and I thought I was supposed to get the oil myself
I will definitely be buying again from this website. Uzi, tr92, CZ72, s56, and f06 here I come
