Wgp trilogy autococker …gun worked well when I used last(full day at the field) but that was 7-8 years ago and I don’t have any air to put into it to test but if u hook it up and it happens to leak air worst case is it would need an o ring or something from it being dry from no use in 7 years(there easy to work on)…was always a fun gun to play with and good way to see if u want to get into autocockers without diving head first and getting a real expensive gun and end up not liking it or if u just like autocockers it’s a great fun very upgradable…comes with barrel plug…
