Hey guys, I looked a little bit an found some great stickies with some of this info I'm looking for.

But are there any good books that go into any detail concerning things like milspec, dwell time both in general and short barrels, pressures involved and gas port size? I'm looking to be able to expand my own knowledge bad as well as be able to pass information on to customers and inform them better.

I know there are several things I don't fully understand like extractor spring styles and why the BCG has holes in the side of it. Any help is greatly appreciated.

Don't know about any such books at the present, however, MIL-C-70599A(AR), MIL-DTL-70599B, and MIL-C-71186B(AR) are available for download in PDF format online (just google them).
