My TSD L96 dosen't shoot straight.

[musicman]

This post follows my previous post "TSD L96 muzzle tip removal"

Even after having realigned the muzzle tip with the inner bore, the gun doesn’t shoot straight at 100 feet. I use .25 g bb’s. Should I try 0.3g bb’s?

I have noticed that the inner-bore is little bit arched because when I let it roll on a flat surface there’s a small "wave". Does it affect the trajectory? Should I try to straighten up the bore?

Also, it seems that the up-hop has no "zero" position. The bb’s tend to fly toward the sky even with lowest adjustment possible. As soon has I try to turn the screw, it becomes worst! I’ll try to clean thoroughly the up-hop.

Please, I will appreciate other advice on how to improve the efficiency of my TSD L96 without replacing all the original parts!!

P.S. Sorry for the quality of my written English. That’s the best I can do.

If your inner barrel has a curve in it it will cause the bb to look like it has too much hop. The bb is probably hitting the side of the barrel at the curved point which puts a spin on the bb just like hop up does. You'll need to straighten the inner barrel or get a new one. You may be able to roll it on a super smooth surface with a heavy wide object, that may or may not work.

like in the other post:

just get a new barrel, you can go with a tighter bore at the same time.

*edit* I have 2 stock barrel if you need them, along with a stock hop-chamber I am not using anymore.
