I bought a Ruger 22 Charger and this CGS Hydra can from United. SBR'd the 22 Charger (10.5" barrel) and added the can. Took almost a year wait from ATF. Very happy with the results, and United was perfect.
Here we go - the Ruger 22 Charger SBR reboot; a FAB Defense stock. much better. If you decide to SBR a 22 Charger, get the take-down version. You will have more options.
