Then I got gready and upgraded the stock spring to a OMW 8kg swarmfire one, as well as keeping the 8kg SG nerf relatiator spring. the swarm fire spring is almost spot on the size of the origanal but when compresed it is longer.
Now the gun has a hell of a lot of spring load ( watching my GF try and cock it is funny ), but acuracy and power seem down.
One problem that i think is irrelevant, but ill mention it incase im missing something is, even though the brass barrel seems a tight fit in the gun, shooting the gun now pushes the barrel out a little, but even when holding the barrel in place power seems down.- ( yep i get the physics on the barrel being pushed out losses energy, and a spot of hotglue will fix this )
also there is some spring noise when fireing. Im thinking the springs are touching on fireing??? I have checked the internals for any leeks/breakages, and they all look ok.
Any help here before I operate as i superglued the plunger head up to hold the spring load would be apreciated.
