Got two DQG Hobi/Spy/etc extension body pieces. Titanium non-through hole which is brand new and a used Stainless through hole extension piece (knurled). They didn’t come with o-rings or I’d include them 
. EDIT: found a new o-ring in a plastic bag, titanium extension will come with an o-ring now!
$10 shipped for the Titanium one (cost me 9.50 or something like that from banggood).
Free plus shipping on the SS one.
