    Very good BUT...

    I received this gun a few days ago, and i have really enjoyed it , i have thoroughly weathered it and made it look much more authentic, however they shipped it with a spray painted orange tip. Why would you spray paint it :(,i have been trying to sand off the paint and refinish it for a few days now. :(:(:(, surely there are better ways to put an orange tip on.

    I could not be happier with this purchase. The gun looks absolutely beautiful and shipping was fairly quick considering the distance it traveled. I would Definitely recommend this gun and Swit Airsoft.

    Excellent Quality

    This gun has incredible build quality and the upgrades done are just as good, its very satisfying to shoot and I find it has great performance with 0.4 gram. I recommend this gun to anyone interested and I recommend Swit airsoft as a company.

Product FAQs For Buyers

1. Can you ship this item to my country?

Absolutely — we ship to most countries worldwide using trusted couriers like UPS and EMS. Delivery is fast and fully trackable. If your region has special import rules, our team will guide you through it. 👉 Check our Shipping Guide for details or message us — we'll confirm right away!

 

2. What is the VT upgrade?

The VT Upgrade is one of our most popular performance options — it includes a precision 6.03 mm stainless-steel barrel and enhanced hop-up unit. It dramatically improves accuracy, range, and consistency, allowing you to shoot heavier BBs with stable trajectory. Many players call this the "must-have" setup for competitive performance.

 

3. Do I need to install the upgrade myself?

No worries — everything comes pre-installed and tested by our techs before shipping. If you'd like extra tuning or specific custom parts, just leave a note at checkout — we'll build it exactly the way you want. Each gun is test-fired and QC-checked before we pack it.

 

4. Can you adjust the FPS (power)?

Yes! We can fine-tune FPS from 300 – 600 FPS depending on your local field limits or personal preference. Just add our FPS Adjustment Service at checkout and tell us your target FPS — we'll handle the rest. Perfect for ensuring your gun is field-legal the moment it arrives.

 

5. About the orange tip — can it be removed?

We totally get it — nobody likes a bright orange tip on a realistic replica. All our orange tips are super easy to remove or replace. If you want both orange and black tips, we can include both so you can switch anytime. Collectors love this option — realism for display, orange for field safety.

 

6. My shooting performance feels off — what should I do?

Most performance issues come from hop-up adjustment.

  1. Reset hop-up to zero (fully back)
  2. Fire a few shots
  3. Gradually increase until BBs fly straight

If the issue continues, contact us — we'll help you check BBs, gas, or inner barrel condition. Our tech team replies fast and helps you troubleshoot like a pro!

 

7. Can I get help after I receive my gun?

Of course! Every order comes with after-sales support and warranty. If you face any issue — performance, shipping damage, or setup — simply contact us with your order number. We'll guide you step by step or arrange repair/replacement if needed. We stand behind every build we ship.

 

8. Still have questions?

Message us anytime — our techs are active players too. We'll help you tune, upgrade, or choose the best setup for your field. 100% tested before shipping. Trusted by airsofters worldwide!
