ya, getting an adjustable gas block and a lw bcg, you'd probably want the lightest buffer. I doesn't make any sense to get a lw bcg and a heavy buffer.
The lighter you can get your system, the faster you can get it to cycle, the faster you can get hits on target. The better you can tune your system, the easier it will be to control your muzzle, the more shots you can keep on target.
For the ultimate headache, well tinkerer's dream, get an adjustable gas block, with Effin A compensator and a reloading bench. Should keep you busy for a few years.
