Great Professional Service. Thank you
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

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
