I have a CZ Scorpion that I SBR’d and got the HB Industries K conversion that came with a new 5.3” barrel
I’ve put about 300 rounds through it (100 suppressed) I cleaned the barrel for the first time and noted a pronounced white streak along two of the rifling grooves. I can’t tell if it’s a divot or discoloration. Is this a normal imperfection type thing?

I am not sure if it is "normal" but I have seen similar in several of my guns when shooting jacketed ammo

It's bullet, carbon, and powder fouling...... In short, a dirty bore.
Clean your barrel thoroughly with a brush, patches, and a good bore solvent. Even after a good cleaning it's normal to see copper or other dark colors against the rifling. |
