Hey this is Tony thanks for the deal with the Colt 6601 put 30 rounds through it and it fired nice. Its a little bit differnet than the big old .308. when i bought ammo i was thinking dang these things are tiny but its been a few years since i have shot an ar15. Anyways this saturday i am taking it to the range and shooting an actual target. i will let you know how she does since you probably have been wondering how it shot for the last 19 years. lol
