FAQs
Quality Standard
In the airsoft world, absolute perfection is neither possible nor practical.
While we constantly work on optimizing the processes, it's still very difficult to achieve perfect results with limited manpower.
Minor tolerances, marks, or finish variations are natural in precision mechanics and never compromise performance or quality.
Support
We take every piece of feedback seriously – but only if it actually reaches us.
Customers who contact us directly will always receive full support: replacement, additional shipment, or refund, handled promptly and without complications.
What we cannot do is monitor complaints posted in Discord servers, forums, or YouTube comments. In those places we see no order number, no details, and therefore we cannot provide a real solution.
Shipping
We aim to ensure fast and reliable delivery to all our customers, whether you’re in the EU or elsewhere in the world.
Shipping is either from our Latvian or Asian warehouse, according to the inventory availability
We will always pick the best lane for your country/area. The average delivery time to EU and UK is 5-10 days, to USA and Canada is 10-14 days, South Korea and Japan 5-7 days

- Orders not yet dispatched can be canceled free of charge.
- EU customers are eligible to initiate return process within 14 days upon the delivery of the parcel
- Returned items must be in resealable condition, otherwise we have the right to refuse the return or reduce the refund amount
- If the return is not caused by our own mistakes, customers are always to bear the return cost
I'm giving this an 8/10. This is an extremely realistic piece, and a great copy, but a noticeable replica. It's much better than the stock VFC G36C style top rail. I would gladly field this, over that. Mine showed up with a very minute defect in the finish. Doesn't affect the function. I will gladly purchase another one. If you're looking for a high quality G36 rail, this is it.
I love it 100 % real
Almost identical appearance to the real HK parts.TM screw kit is applicable.
The real thing is very hard to get, but thanks to CLUTCH PRECISION, I was finally able to get my hands on the KA4 upper rail. Compared to the real thing, it is made with great attention to detail, and I am very satisfied with it. What's more, it's not too expensive, which is nice. The only drawback is that it cannot be installed unless you rub it together. I was able to assemble it successfully by rubbing the rail part of the product rather than processing the upper receiver, but I felt that it might be better to leave a little more clearance.
However, apart from that one point, there is no doubt that it is a very satisfying product.
I can confidently recommend it to users who can adjust the rub-in themselves!
