Nothing really wrong with a COLT, My HBAR was a dependable shooter just under 1 MOA with pretty much any match bullet I ran through it. If you can possibly have a gunsmith bore scope the first couple of inches past the chamber for heat checkering and wear. I get nervous when I see a 100 round magazine. A guy that likes to really let them fly can get a lot of leade/rifling damage from heat build up.
