Yup. I bake after each color, which is where it can get really fun when you're doing a pattern, and why you might notice that none of my guns except for one has any kind of a pattern on it. It's actually faster that way than waiting the amount of time that it takes to let the H-series air dry to an acceptable level, and I need to be able to apply templates and handle the parts when matching the pattern.
I wish my little 16" looked like the 20" above.

In most of the uppers I have put together the extension does not fit in the tunnel as tight as I would like. I was thinking that a coating would be a good to tighten the fit. How thick can you build up the tunnel? Is there something else you can do? Dont laugh maybe a a layer of aluminum foil? I do not like the idea a blue locktite.
This is why some companies specify certain ID's when having their uppers made for them, or machine shops that make billet sets cut theirs with tight extension tunnels, like JP & Mega, requiring a temp fit. Tight fit and temp fit seem to be the best approach, with bedding compound being the next best. All should be square.
I think I have seen at least one person use aluminum foil and blue loc-tite. There really isn't an issue with using blue loc-tite, other than needing a little bit of heat and some Kroil or thin penetrating oil that is allowed to set overnight when you want to remove the barrel.
