9mm AR Barrels Twist Rate

[deltaenterprizes]

I haven’t a PSA 9mm AR with a 1:9 twist rate barrel. This is not optimal for cast boolit shoot unless using 147gr boolits.
Does anyone make a 1:16 9mm AR barrel?

You can get a blank here, https://www.shilen.com/calibersAndTwists.html . The blank will need to be contoured, chambered and threaded and a gas port drilled.
