Spare fartflap + knife

Spare set of 3 fartflaps for your Silencer + sharp knife for making the cross cut

-Model Core & Big Boy (fartflap = 32 mm)

-Model Inset (fartflap is 25 mm)

you need a very sharp knife to make the cross cut. A hobby chirurgical knife is the best. 

(if you order the spare foam set, fartflaps are already included in that set)
