I’m associated with coatings industry. DLC is done in batches by a third party coating firm and not Zev. Zev won’t know if the firm prepped and coated correctly in a batch until they are fired. I’d say the people doing that batch either did that one too thin or didn’t prep it right prior to PVD...
They aren't AR lowers made BY Glock they are made by various makers like Frontier Armory, QC10, etc and allow you to make 9mm ARs that take Glock mags instead of the traditional Colt SMG 9mm mags. I was wondering if anyone around here stocks them or distributes any brand of them.
Their ATF letter says it's ok to do over 26".
But the letter is addressed to them....so take that as you will. I personally doubt it would apply to you any different but do everything at your own risk.
I want to pick up a few soon and would rather pay a couple bucks extra to pick up locally/support LGS. Who has some at a good Price. Andersons and the like are fine....not looking for anything fancy. Just trying to complete a few kits I have.
