Listing Detail Tabs

Auction is for:

1 x spanner and
1 x Gunworks standard rear hex suppressor bush bored to 16.1mm

Free Spanner:
Lightweight Green polymer spanner is 6mm thick

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.

To combine freight on two items when using 'buy now' when freight charges are different. Pay the larger freight amount on one item, & on the other item (with the smaller freight amount) choose the 'pick up' option

If the freight amount is the same on both, just pay one lot of freight & choose pick up on the other auction(s)

We don't offer free freight, as its never free so lets be realistic about that, even if TM isn't!

All prices are as stated in the listing thanks
