all 4 are M3 size tubes.
the 25x36 is the new style powder coated with metal endcaps
the 3 25x33 are the older, annodized aluminum style with metal encaps
all 4 are in good condition, and not overly dirty.
will trade for 4 23x31's with metal endcaps.
let me know quick, otherwise this time next week, I'll be pulling the encaps and taking them to the chop saw to make the 23x31's
