CO2/HPA Conversion kit 12g Cartridge Converters HPA Kit, S-TW and RG Threaded, 8mm Quick Disconnect

works great, fits the Umarex Brodax without any issues,but package didnt not come with any sealant lube as some youtube videos said it did.

Got the RG Thread for Elite Force 1911 Tac and ASG CZ P09 CO2 airsoft pistols to use HPA tank with 800psi. The cartridge fits a newer 1911 Tac Mag, but it required a bit of shaving at the bottom to fit into CZ P09 mag and an older 1911 Mag. Once I got it to fit in, it works great. Looks to be solid and no leaks. Happy to be saving money from buying C02 cartridges.

This has not leaked at allIve got my regulator se at 2000psi. Needless to say my cross dpms shoots 520fps no problem.But the threads on the rg version and the st-w are slightly different then the crossman dpms. The bug blaster uses the st-w version. Same thing the threads are slightly different. Probably metric and standard. So close that I just force it to cut threads. Not advisable. But I've done it now 4 times and it works. It would be nice if the threads matched.

Didnt thread well
