BCA barrels?

[Lastrites]

I just ordered this:

I was going to make my own from rebar rather than spend $100 on the Geissele.
I figure $50 is a good deal. There is a cool video on this page on how to use it. Upside down.

On my way to the range to shoot the BCA. I will report back later.

That also allows for a 1/2" end socket to be inserted in the end of it to mount in a vice. Don't recall the size off hand.

Also, Botach sells one for $60 that has flats on the side. I do recall shipping issues with Botach many moons ago, I won't vouch for them.
