I used this rifle for no more than 5 games and the trigger switch broke. I attempted to install a Jefftron Leviathan into the rifle but could not put it back together. I contacted my local shop and they told me it was a year wait. I have no more patience for this and just want to recoup some money. It works BEAUTIFULLY with an upgraded hopup but I never had the opportunity to run it with the Leviathan, as I am not tech inclined. The rifle worked well up until the trigger switch snapped so all this needs is put back together. Base gun was 350 and the Jefftron was 170 when I purchased it.
