Free float barrel nut

[Rinodods]

Anyone know what thread dimensions a standard free float barrel nut uses? I keep looking online and can't find it called out. Thanks for the help.

There isnt a standard for the most part.

Calling the manufacturer is going to be your best bet.

What Hoser said- Most barrel nuts are proprietary to the manufacture but the receiver side is 1.25 x 16 TPI
