LRB No 2 that I put together a few years ago. They had just started to sale the Criterion barrels. I searched long and hard for the best parts and ended up with H&R pretty much on everything except the barrel and receiver. Ordered the flash suppressor from Elmer Balance (first manufactuer of Springfield Armory M1a's) in Texas. He was still selling a few parts as late as a few years ago.
Also have a 1990 build SA M1a, 7.62 heel marked that has a SAK barrel, TRW bolt, TRW op rod and complete TRW trigger group. Great shooter.
Both rifles were are rack grade weapons. No National Match parts or enhancements.
