    Two new lowers had holes drilled after anodization (pic)

    After speaking with the company all is well. lowers were anodized and as others pointed it it was due to a bubble preventing the dye from reaching the hole

    Someone with more knowledge should be along and may correct me if I'm wrong. I think the buffer, when rifle is fully assembled, will be "hammering" on the BCG not the retainer. When you push the upper into the lower the BCG sets the buffer back a small amount keeping pressure off the retainer. It only has pressure on it when the lower is separated from the upper.

    ^^ The buffer never hits the detent when you're shooting, it just keeps it captive when you separate the lower.

    Functionally it probably doesn't matter. You could try some of that aluminum black or alumahyde from Brownells.

    More and more things being rushed through production.

    Yep, the buffer doesn't hit that detent during operation, so no wear point.... BUT, that is a carppy solution that manufacturer did. Makes me wonder how everything else lines up...

    a well known and respected one. I'd rather not say yet since I haven't yet reached out to them.

    Blind holes can trap a bubble during anodizing.

    If it were my lower I wouldn't worry about it.

    I'd say a bubble might be possible as well but this is on both lowers and both have identical scratch marks from the tooling after it was anodized.

    Thanks well, I sent an email to the company already so I'll wait to hear what they have to say. It's good to know they are good to go thou.

    As for pricing I paid $233.00 for both shipped after transfer fees.
