Here is our selection of target refills to fit our airsoft trap targets when buying the refills please make sure that you are buying the correct size. They come in two sizes either 14 cm or 17 cm. The SMK type of refills are mostly made of card and are for use with the metal type traps. But you could still use them by sticking them to a cardboard box all a tree etc. The paper type of refill targets are mostly for the BB gun trap targets like the Swiss Arms or well net target we sell. And remember we are never beaten on price so if you see it cheaper just let us know and we will quote you happy.
