Richard, member, from TX, United States, asked on April 22, 2025

What threaded barrel is needed to make this flush mount?? I purchased a set but my ( threaded barrel) extends out too far). I have the hellcat pro.

Answered by Matt, member, from MI, United States, on June 22, 2025

I have the hellcat Pro too and they have a really nice comp for it but they do not have a barrel for the 3.1", which takes a 3.7" 1/2x28.
The same thing happened with my SIG P365X Macro, it has the same size barrel as the Hellcat Pro 3.1" and I bought the barrel they recommended and had to return it. I ordered the threaded barrel for the SIG 365XL and it fit like a glove.
