Extension tube to fit QB/TF or Crosman 12 gram CO2 rifle Models 160, 166, 167, 180, 187, 400, 1100, Mac1 bulk 622's & Sears Variants of early Crosmans. Made in USA by Mac1. Blued Steel. 11 for Tube nearly as long as the Barrel of the 160 or QB, 8" allows for the use of a Brake on the barrel & 5" stubby for extending Crosman 600, 150 & Rifles that you want to add a smaller bulk capacity, The tube is manufactured with the QB Metric threads on one end and Crosman SAE thread on the other so it can be fitted to a wide variety of CO2 Airguns. CO2 Extension tubes are meant to add CO2 capacity to Bulk CO2 systems or air systems regulated to CO2 pressure levels of 800-1000 PSI. This is not recommended for High Pressure Air Applications.
Recently QB adopted a new version tube with vent hole about 1/2" down the tube threads rather than the last few threads. I refer to this variant as QB 2013+. If you need a 2013 version of the QB oring coupler it is no extra but you need to make that option choice/Version. It will fit all so if you do not know for sure the 2013 o-ring coupler will fit all QB & Crosmans but it is needed for the new QB guns for the gun to seal to the extension tube. Original o-ring couplers don't reach far enough to get past the new vent hole so I made a new one. The long side of the new o-ring coupler needs to go into the guns tube and the short side goes into the extension.
