...the tko's are better... it'll work well on a benjamin discovery or maximus pcp barrel, too.... i spoke with texas airguns about his devices a week or two ago....there's also a place called airguns of texas out in abiliene , but they do mostly pcp stuff from what i recall. i bought my 3d printed device from a guy on ebay... $41 for a pickle to add onto the shroud of a benjamin woods walker carbine.... froggy's place or something like that... we was in louisianna , but now here in waxahachie, tx.... i had to get some the plastic 'hairs' and waste out of it with a brass barrel brush , but it was accurate after that... the plastic is not as sturdy as tko uses , but getting less expensive all the time... - paul. -ps: hey gunguy (gunsrus) , it would be really nice to see some photos of your sheridan 2260 when you get it shooting right.....
