So the other day i was getting 110 m/s with m130 spring with 0.32 BBs with around 1.88 joules , ran it through a full day of match and now its down to 105 m/s around 1.75 joules ... what happened !?!?! i checked the seal its perfect ! even submerged the piston in water to test it out and no leaks, the nozzle hits the silicone lips perfectly. Could it be the spring getting weaker and weaker ? Or the O rings fail under high pressure of the shot ? Could the tappet plate affect it ? Thank you in advance ! Edit: i got an upgraded Hera Arms Ar15 with 0 Cylinder, 455mm madbull barrel, Maxx nozzle ,piston head, hop up and cylinder head. basically DMR build.
Silicone grease, and spray to clean and lube your barrel. Vaseline, don't use it, it hardens over time and as it's oil based, will rot your O rings and hop...
