Hop up rubber question.

I've got my pistol hop up dialed in for distance and a nice fairly flat trajectory ( about 27-30 meters seems to be where my accuracy begins to falter). I've noticed a tendency for the bbs (when not on target) to swing up to the side.

Removing my barrel and taking a peek... I seem to see the hop up bucking sits at an angle in the barrel. Should it be perfectly horizontal? To my brain this seems like.. Well... A no- brainer, and the answer is "yes". But, not having owned a dozen airsoft guns, I just want to know if I'm making too much of it.

It's a TM G17 custom, bone stock. .2 g Bio Devil Ammo, propane.

Thank you.

Yes, the bucking that is sticking down into the barrel should be completely level to give you a straight trajectory. If it's canted to one side you'll have BB's veering off to one side.

There should be a "line" on the barrel and the bucking that will sit in the groove so that your bucking is right side up.... If it's not then that would explain the veering to the right consistently. As far as better accuracy, use .28 if not .30g. It does make the BB move slower but IMO the tradeoff in punching power to go through brush and the increased accuracy in effective range are worth it. (NB: Going to a heavier BB actually lowers overall maximum range however increases effective range).
