Wow, it’s been years since I’ve been on here can’t believe it’s still around. And really can’t believe I recognized your tag along with a few others. I just dug my blowgun out the closet and want to start shooting again. Looking at your post I’m interested in the pipes you ordered, have you used them yet? Do you see any difference in dart speed? Are these pipes polished inside? I’m looking for a 6 foot one piece .625 and at least 3mm walls.
