In 2020, APS brought to you a new End Cap device – 1 Step End Cap. (Item code AC095)

In this new end cap, user no longer needs to turn outer or inner part by the use of coin or tool. User can simply use a 6mm Allen Key to turn the cap. After a full secured turn, wait for 1 minute to let the Co2 flows within the magazine, the pressure will then be stabilized, thus giving you a stable shooting velocity on each shot. This new device works perfectly in most situation. However, if you were living and playing our Co2 Pistol in cold weather, say < 10 degree celsius / < 50 degree fahrenheit, we still recommend you to use our old end cap which work best in all situation.
