When I opened it up, i realized that it has a fairly large plunger chamber, NF size. It also has a longer, stronger spring. The reason that it gets such crapola ranges is because the air has to go through a small tube, around a kink, and THEN push the dart out of the barrel. It gets better range with the barrel extended up only partly because it is pointing up, also because the tube isnt bent as much, so there is no kink, like if I have the barrel extended up but puting the barrel flat, it gets some remarkable ranges compared to the barrel not up. So if I maybe get a larger tube to connect the barrel to the plunger chamber, it could get possibly NF type ranges. OH and I am also using stock micros for these ranges. Stephens will get better, but I havn't had a good stephen to use in a while, I'll have to make some new ones.
oh and sry but how do you put pictures directly on the post instead of putting a link? I tried and it said, that is invalid, then it had a example website that said, domain or something.
