Put a new upper together today and stuck the borescope down to line up the gas block. Never seen a barrel that looks like this. Thoughts?

Chrome plate over pitting?

Reason #10,000 to never scope a bore.
That almost looks like it was full of tiny bubbles when they plated it. |

Almost like there was rust pitting on the barrel before chroming and it was ''cleaned up'' and chromed.

If I had to guess...
Something went wrong during the electro polishing stage prior to chroming. |

Ok thanks I didn’t think it looked good. I’ll contact the Mfgr and see what they say before calling them out. Things slip by, but if the blow it off or don’t make it right I’ll let y’all know

I can almost guarantee that if all of us on ARFCOM had borescpoes, at least 1/6of our rifles would have some type of fuckery that slipped pass QA

 Attached FilePitting or poor gas escapement are likely the issue/s. Hard to tell from pics if if concave/convex in profile. |

You should definitely buy one. @ziarifleman You.... have a funny mean streak... Lol and in the spirit of funny mean streak's... be sure to use the "I can't believe you didn't have the Local Oil change place , change the air in your tires... have you ever had it done ? They should be doing it every time... dang.. how long has it been ? NEVER !?.... omg....." When well played... on the less knowledgeable... you can milk this harder then Canned Steam Back on topic.... I kinda want the barrel... I'd love to see if the pitting would completely beyond belief jack up accuracy.. before the pits were filled, and then after the pits were filled. |
