請問壞處係........
thx

Red tube is "full cylinder" scale, it should be used for 509mm, M16 full size barrel. It produces too much air for 10.5-14.5" barrel, extra air will disturb the BB.
Used back blue (M110) or gold (M130) tubes. They both have a small slot at the front, and less air will be produced
