bought a barrel from a sponsor here that is melonited. Was told the manufacturer was bulldog barrels.

Question is - Why is the bore grey/silver?

Melonite turns the metal black. The outside is black. Al other melonite barrels I have owned were black inside/out.

Was this melonited and then rifled? Why would a manufacturer cut the bore after meloniting? Am I missing something?

It should be black inside and out.  



When you patch it, it should come out dirty with a brownish tint, clean the hell out of it before shooting it!



It should feel slicker than any other barrel you have ever patched.




That's how mine are.

Bumping to see if anyone has more info on this. I tried to contact Bulldog Barrels, but their website and phone number do not work

Melonite barrels are treated inside and out (usually black in color).

Ionbond barrels are only treated on the outside leaving the bore it's natural color while being black on the outside.

Do you have any insight on bulldog barrels?

Ok, thanks.

I contacted the place I got them from and they agreed that it should be black inside/out. They are exchanging them for me.

Has the barrel when shot or used?

my S&W ar15 sport claims a melonite barrel and the rifling is shiny.

Depends on who did it; nitriding all by itself is gray. Usually the black finish is phosphate/oxide on top of that. the Melonite QPQ process adds a black finish, but just just because it isn't black doesn't mean it isn't nitrided.

I can guarantee you the bore wasn't rifled after meloniting. It would be nearly impossible to cut the rifling afterward, and even if you could, you would lose the protection the meloniting added.

My guess is you are returning the barrel for nothing.

There are different forms of Nitriding.

I've never seen a barrel that's been Nitrided AND Phosphated.

Or the new finish they have gone to.  They have deviated from the shiny black finish back to the phosphate finish again.

Is it gray or black? The flat black is oxide; the old gray finish is phosphate.
Looking at some Gen4 pics online sure looks like gray phosphate again.

I have seen many melonite barrels. Mostly from ARP and Adams Arms. They have all been black inside/out.

Like I said, the bore was almost a white color it was so white. The rep where they came from even agreed they should be black inside/out. That is why they are taking them back.
