Well,LRRPF52, I ment to say inhanced bolt with carrier...The upper was built by SAOD with the carrier they provided and seems to be a standerd type (not the light race gun type)...The stock has the typical A3 tube and spring and yes it is a rifle length system. I've been trying different weight bullets,100 gr nos.bul tip,120gr sbt and 123gr.horn amax...
So far the amax groups best at 1/2 min ... All the rest of the things you ask I dont really know. I will say that I've been running with a dry bolt, could that be a reasion for gas to prematurly escape causing a short stroke? Had an experiance with the .556 were oil found its way into the chamber causing a case seperation. So I try not to get too much oil in the carrier and slam on an empty chamber. Scary stuff.
