I own 2 Colt's, CAR 2764's, and 2 Bushmaster's, both are V-Match, one 16 inch the other 20 inch. The "4 ARE UTTERLY RELIABLE" not one instance of unreliability, in any way, shape, or form. One of the Colt's has a JP Enterprises fire control system. The rest are box stock. They all shoot my handload into 1/4 inch 25% of the time, 3/8 inch most of the time, and 1/2 inch with my eyes closed. Choice between the two, Bushmaster for the difference in cost. I don't see enough difference in operation or performance for the cost difference. I'm not counting resale or collectable.[:D][:D]
