This is a new trigger that is out on the market for the TIberius Arms line of markers. I pre-ordered the product and had about a 2 month wait before it was available but once I had it installed it was a night and day difference between this trigger and the stock trigger. This trigger has a much lighter pull to it and feels much more natural than the stock trigger and it looks awesome on the marker as well. It's also made out of aluminum so it doesn't have the cheap plastic feel to it. The only cons to the product was that I had to file a little of the plastic off of the safety mechanism for it to fit but the safety still works and the trigger is awesome!
The Scythe Trigger for Tiberius Arms Tac 8 / T9 Marker is older, so while it may be available used and in a few cases new, it is not commonly available anymore.
