Free Spanner:

Green spanner is for removing the delrin bush from a Gunworks Suppressor when you have 1 suppressor for 2 rifles and you need to remove the bush in the rear to put in a different sized one.

This doesn't mark the back of the suppressor like a cresent will, and also allows minor adjustment of the bush fit but screwing it in tighter to reduce the hole diameter slightly.

How do I find out what diameter I need my bush bored out to?

Easy, put your Gunworks suppressor onto your threaded rifle (rifle must be threaded to get an accurate reading) and screw the suppressor on until it is nice and tight on the barrel.

Use verniers to measure the diameter of the barrel where the suppressor finishes (see pics) you can place a vivid pen mark at the same spot and remove the suppressor to take the reading if you wish
