Faulty Product?! Unfortunately that is part of life but be rest assured we are here to help! Contact one of our friendly staff via phone or email. Stating what the problem is, if we can resolve the problem via phone or email great if not then they will advise how to send it back and what details we require.

Two tone
We can two tone any weapon we sell at Bespoke Airsoft. The purpose for two toning is if you do not hold a valid defence under the Violent Crimes Reduction Act (VCRA, 2006) which is to prevent the misuse of Replica Weapons, which applies in England, Scotland, Wales and Northern Ireland.

The gun will be sprayed 51% in a bright/primary colour (we do only blue currently). The process of two toning currently runs at 2 working days depending on Drying Time, which is effected by Ambient Temperature and Weather. and currently no express delivery is available for this even if you select it at checkout.
