AR-10 buffers & springs

[MovedWest]

N00b question, but the .308 platform is new to me. I'm building a .308 lower and am planning on using the Buffer Technologies Enidine Hydraulic Recoil Buffer. The Tubb speedlock springs appeal to me for their noise dampening ability and shot-to-shot recovery. I plan on using this rifle for long to extremely long range use (100yd - 1000yd).

Does anyone have any experience with either one of these items in the AR-10/.308 platform and can shed some light? Recommendations?
