.593"ID - .664"OD

The carbon fiber extension tubes you made and delivered to me are great! Just what I wanted and needed. Thank You! I'd like to see an offering or two around the .450 to .550 inch ID range. I like to extend blanks in the ML, M or MH range that have butt OD's of 0.450 to 0.550 inches. I like that you offer the same tubes in a choice of lengths, too. Great product! Les Cline
