@grdwaste The double barrel and barrel to funnel are very similar. They have a pretty smooth pull with a small amount of chug. The barrel to funnel chugs a little more than the double barrel because of the restriction from the longer uptake tubes. However, the barrel to funnel is a proper recycler where as the double barrel is more of a half recycler.
I haven't used the Klein incycler but I would say wait for Stevens version as I'm sure it will be better since
@blankrider is helping tweak the design.
I can post a video of the double barrel and barrel to funnel when I get home in like 6 hours.
