[QUOTE="quigley257, post: 3059144, member: 84442"] If you buy the lapping fixture or borrow one. the procedure is quick and effective. Some uppers require only a light touch to get complete contact while others are quite a bit more out of square. I've seen "name brand' uppers that needed more lapping than the cheap ones. I use the green Loctite to set the barrel in the upper. The 6mm ARC I built using random components and an EABCO accuracy barrel shoots fantastic. I also made a spring loaded 6ARC cartridge to make lapping the bolt and lugs easy. None of these things are hard to do and seem to help with accuracy and consistency. There is a great sticky thread on AR15.com that details all the tips and tricks for building an accurate gas gun. Nearly all these things are doable by the DIY builder in a home shop environment.
