I am thinking it is time for an new AR for coyote hunting. I have a rifle in mind. The rifle i have in mind is an Oly Arms K-16. The rifle will come with a FIRSH (quad rail) Hand guard so that i can mount a light for night time coyote hunting. The K-16 is a 16" Heavy barrel with a 5.56 chamber. Oly is supposed to have really good barrels but i dont know for sure. I did own a SUM Oly barrel once but i wasnt all that impressed with it. A lot of guys talk like there Oly SUM barrels are hammers. Maybe i had a dud???? Anyway if anyone here has one of these rifles i am talking about please share some info. thanks Lee
