Well, I finally got my Mad Bull 6.01mm Tight Bore inner barrel (509 mm) installed in my CA M15A1 and got it tested. Since a picture is worth a 1,000 words, please see the attached.

Other than the barrel, I'm using all the standard stock CA X Series parts (hop up, bucking, etc).

The standard CA barrel (6.08 mm?) shows a 4.5" grouping of 10 at 65 feet while the Mad Bull 6.01 mm shows a 3" grouping of 10 at 65 feet (note: gun is NOT benched. This is me holding it).

Not bad, I was hoping for better.

What really shocked me was the increase in muzzle velocity (0.2 g bb)

Standard Barrel:

370 fps
377 fps
364 fps
373 fps
373 fps

Mad Bull 6.01:

410 fps
393 fps
402 fps
405 fps
410 fps
