UGS CO2 Inserts
Our CO2 inserts are manufactured for the UGS stock and have models for both the 12g and 33g disposable CO2 cartridges.
By changing out the stock's rail you are able to reconfigure your UGS from running the standard 13/3000 HPA tank to a low profile, Milspec buffer tube sized cylinder so you can use Milspec AR buttstocks.
So, you are probably wondering how many shots can you get out of these things? Based on an F2 running at 1.5J w/ .28g through a 6.05x380mm barrel, a 12g will average approximately 180 shots while the 33g will average approximately 500 shots. While these may not be the greatest if your playing style embraces the "accuracy through volume" concept, they are ideal for milsim scenarios where shots counts are lower and realism is higher
