“Melonite coating was a little thick. Makes difficult to insert into gas blocks with a tighter tolerance. like a spikes tactical gas block for example. Other tubes slid there fine. I had to buff the coating off of this tube in order to get it to fit in the gas block.”
Hello, Melonite / QPQ is a surface treatment rather than a coating and doesn't add any OD to the item. If you ever have a problem with something fitting simply contact us. We're glad it worked out for you with a little buffing.
