Questions & Answers
Has it been shot suppressed? Or spinning jacket of the bullets

This question makes no sense but these barrels and the twist rate are designed for the heavier subsonic ammo , which is intended to be shot suppressed.

by Mr. Gazoo the gunsmith, Verified Owner, December 7, 2025
Is it Dimpled for the block?

No. You'll need to do that yourself.
