Is lapping the upper face worth the trouble?

[QUOTE="ka30270, post: 3059022, member: 10067"] I have a few ar's and am about to put together a couple more. I'm curious as to whether lapping the upper face is actually beneficial to accuracy or if it's something that sounds good because it helps on a bolt rifle. Bolt rifles don't have an inch of barrel extension snuggly fitted into the upper to keep things "straight". I'm wondering if a properly mated upper and barrel would even torque it out of alignment if it wasn't completely square. Then you have also removed the anodizing and it could allow corrosion on the connection. Thoughts? Thanks all [/QUOTE]
