i did not specify that...actually i didnt have darton do it for me. i ordered the sleeves through my shop and then saw i would need a cnc machine so i sent it to the shop that does all my cnc work....i think ive got 1100 into the sleeves and labor. i just had them install sleeves. i take it then that that is not a common practice even for darton to do?

edit: sry just did some quick math ive got 900 into sleeves and labor...paid 600 for the sleeves and im thinkin they told me it was 105 a cylinder for install
