    Could someone please explain to me what NTFE Nickel Teflon Coating is exactly?

    I am interested in a bolt carrier (Like DS Arms sells) that is coated this way.

    Is this just a gimmick or are there any real advantages? Any downsides? Does it wear well?

    I think Robar's NP3 might be a type of that.

    EDIT: Buy a quality phosphate bolt carrier group and spend your money somwhere else. I have a few coated ones, and it's totally not worth the money.

    The DS Arms "Sand Cut" carriers are very well made. I'm not convinced the coating is an improvement but the carrier bore and gas key is still Chromed on those NTFE models (Or was on the units I have inspected and own).

    It is really not the money in this case. I am looking at the DS Arms FN FAL bolt carrier. It is a $10 difference in price from the NTFE one and the one with the manganese phosphate finish.

    only issue with Teflon is that over 530F the Teflon starts to breakdown and outgas and inhaling enough of the fumes could make you ill with Teflon Flu which I assume is similar to when you weld or heat galvanized items and get flu like symptoms. I do not know if milk will help with Teflon like it does zinc
