Well the standard 5.1 inner barrel length is 112.5mm. If your suppressor 130mm, then your potential maximum length is 242.5mm. That's double the original length.

With stock valves and propane, I'd estimate 0.20g BBs to shoot from your gun at well over 350fps. Even a 2" increase over stock will put the gun shooting over 325fps, and that's already bordering the limit for the Tanio Koba Twist barrel's capabilities.

Longer barrels do have slightly more accuracy over the shorter ones. My 7" inner barrels are more accurate than the 5.1 Twist. I'd recommend going that route if it meets all your requirements.

This man is correct. With my TM 5.1 that has a 7 inch 6.04mm tightbore and everything else stock, shoots 340 fps.

what does a twist barrel do? does it do the same as rifling on a gun?

No. It puts a cyclone of air around the BB to keep it from touching the walls, like a cushion.

It's a weird concept, but strangely enough, it really works.
