Got the 1322 , installed the ftp kit, and lubed the trigger parts, with a good quality synthetic lube, and its fine for good accuracy. If you mod much more , then a longer barrel is required, as the pellet is long gone before all the air is used up...so wanna spend 500 bucks to make a carbine, or just go with the ftp , and enjoy a hard hitting compact unit, at low cost, and less pumps..
ps, did crown the barrel when I had it apart, and it shoots into the same hole at 10 meters with 14.3 grain premier pellets.
the sights, rear I swaped ends, and went for the peep, and dished out the plastic front , and jb welded a fiber optic rod on it...
Cheers
