What is the diameter of 1/2" FBR? Is it 1/2"? I'm buying PVC from McMaster, and I need to know. And I have no idea on how to measure the diameter of it, my ruler is too inaccurate.

It varies. Tell us the brand of your FBR and someone may be able to help you. However, I can tell you that most FBR is not 1/2" in diameter, usually a little more.

I broke my clippers trying to cut the spring. So I couldn't break the spring with my bare hands so I used a hammer to pound the clipper handle and one of the clippers broke off.

If you bought (or are going to buy) your foam from mcmaster then you want part# 48855K21 to be your barrel.
The Barrel ID needed to shoot 1/2" FBR is anywhere from .505" to .545" depending on the foam you're using. I use Dennis brand "Caulksav'r" polyethylene foam rod from mcmaster (part# 93295K33 or 93295K43) and my preferred barrel ID is roughly .53"

The little critters of nature, they don't know that they're ugly. That's very funny, a fly marrying a bumble bee. I told you I'd shoot, but you didn't believe me. Why didn't you believe me?

Thanks, Captain Slug. That's the barrel I already found, and K33 is my FBR. Is that a tight fit or a loose fit? I'm looking for a loose fit - it's for an air gun.

I haven't heard of K33... how does it fit in your stock barrels?
