yea its 223. stag has been around a while. Ive not seen/held one. these things jumped in price oh about a year ago for the life of me not sure why. did you see the remington? they have a stainless/camo at my local shop that keeps calling my name but its a little more than i care to pay. i look at these guns for the most part as guns built for rounds down range, which is the reason for a 30 round mag. thats why i went with the cheap ammo of the 223. this dpms 308lr one the other hand is built for a different reason. its heavy 10 lbs plus and very stable on the bipod
