Heavy Metal Airsoft talks about these outer barrels for Hi-Capa GBB pistols from Sanctus Customs. These have 1mm+ internal threads for use with suppressors/tracers. They have non-tilting/non-shifting design; the outer barrel is fixed and does not shift like the stock outer barrels... "After 4+ years of use and abuse I can say these are the best bang for your buck!"
