Mine struggled to make a pellet exit the barrel at first


Breech seal was nicked from new

Added a chopped down 14mm diameter spring guide from a Remington Express, added a new breech seal, put a pair of 5p's inside the piston and upgraded the piston seal and now it's doing 2.4 ft/lb with RWS R10 7g but oddly with RWS Hobby 7g it only does 1.5 ft/lb
