[bongo321]

hi what is the polite way to add a sound mod onto your license that i own , i did it with a mod i had before ,But they did a 1-1 airgun one ,??long story they got all mixed up , but in the end they put a mod down as a misc for my rimmy i had a slot for allready .I get the feeling They really want me to go to a RFD buy 1 and add to my ticket but ive got 7 suitable mods to use so how ,, Even if i buy one off the forum how would you add that to your ticket , ive got a note in to them saying ive got a pre-owned mod that i intend to use it ,BUT im not sure if to post hence asking for advice here or is it easier to count my loses and buy another mod ta gerry

I'm slightly confused, but first off you must have a slot.

 

If you buy/or already have a non FAC mod that you wish to attach to a FAC tool then simply write to your region and tell them.
