I am building my first AR based on a Satern match barrel in 264 LBC and a Mega Arms Billet upper. There is a ledge where the ramps in the barrel extension meet up with the ramp extensions in the upper. Mega tells me this is not any problem and ammo will feed fine. The retailer I bought the upper from says that it is normal to have to dremel ramps in a barrel extension to get them to mate up properly. See the attached image below -

Any help or advice would be appreciated. I am putting too much cash into this build to have anything other than perfect.
Thanks!
