I have a kit that I purchased awhile back from Gun Broker. The seller said it was a Bulgarian 5.45. I sent it out to Troy at inrange to have it built. So Troy calls the other day and says its finished and says it runs great. Then he says it liked the M193 Lake City the best. I asked him if it was a 5.45 and he laughed :roll: You didn't know it was 5.56. Now I have to buy more mags. Should I keep it or sell? Whata you think. If I keep it I will Form 1 it.
