Hey guys, new to the forum and looking for some advice. I'm building my first AR and want to build a high quality tack driver. The main thing I will be using it for is coyote, antelope and deer hunting. I'm wanting to be able to shoot out to 600-800 yards, I am getting it chambered in .223 wylde and am planning on purchasing a Krieger barrel 1:7.7 twist. My first question is; Is it worth going with a Krieger? I've heard alot of good things about them but are they worth the extra $$. Secondly, if I go Krieger is it worth getting the chamber and headspacing done by them? Lastly, I'm torn between 18 and 20in barrel. I don't want to lose velocity or accuracy since I'll be using it for long distance hunting, but I'm concerned about a 20in being too heavy to lug around, especially since there is a good chance that i will be suppressing it in the near future.

Any thoughts or experience would be greatly appreciated thanks guys!!

Definitely a 20" barrel but have you considered the 6.5 Grendel? 6-800 yards is pushing it for 223/5.56 some ammo starts the tumble effect at that distance.

I have a 20" and it's not to heavy for myself but I would invest in a great sling.

I have thought about the 6.5 Grendel but like the availability of ammo for .223 and option to shoot 5.56 Nato. Any experience between the two?

Well 6.5 is optimum for hunting out that far and .223 is more accurate but has less velocity normally than 5.56 both will touch out that far but your def. going to have to practice a lot with those rounds since bullet drop is more

BB:  For accuracy, Krieger is among the very best, highly regarded for the NRA National Match Course.   Get the 20" for sure, don't mess around. Let Krieger's shop do as much of the work as possible, esp a matching bolt.   It will be heavy though.  

Bear in mind the limitations of the little .223 round.  Its good for shooting rodents and maybe a coyote, but not for deer and antelope at extended ranges.  Check out the 6.8 round for hunting, maybe not at 600 yards, but within 300 yards or so its a very good choice, IMO. - CW

PS:  FWIW, I love coyotes.  Hereabouts I shoot grey squirrels, an invasive species, and put them out for the local coyotes who roam the neighborhood at night policing up little dogs (another invasive species) and unwary cats.

You won't be killing coyotes consistently at 600 yards thanks to the energy and bullet performance of a 223.  You're going to loose a lot of dogs. The best BC bullets just won't do it for you as the SMK will not do it on expansion  

You would be better served by using a 6.5 or even a 6.8. Bullet weight will help a great deal but to me the challenge of reading conditions and range estimation would preclude me from doing a whole bunch at anything past 400 yards. It takes a heck of a good rangefinder to handle them out that far.

A Bartlein barrel from Compass Lake will be as good as if not better than Krieger, but it's splitting hairs.
