New Oregon 24AP is the new 1/4 .043[1.1mm] super fine mini chain from Oregon… Is it better than the Stihl 3670-71PM3? Unlikely… Is it better priced – yes. Does it have the bumper drive link – yes. Is it worth a try – absolutely! Not available in reels only the sizes as per website so if we ain’t got it you ain’t gonna get it!
