Hey guys. So I'm finally getting my 18" upper built. I have an 18" Satern barrel that came with a "matched bolt". I'm not sure who makes their bolts but, to my untrained eye, it looks like a regular bolt. I'm using a JP FMOS bolt carrier and it came with a bolt that looks pretty trick, and is made from Carpenter 158.
My question is how "matched" are Saterns bolts to their barrels, and am i better off using their bolt over the JP unit?
Thanks
