whats a good upper/caliber for an AR

[breethwithme]

I'm gonna b buying a new upper for one of my AR's there both the standard. 223/5.56 which is a good round I.e cheap. It can probably take out a deer but I'm looking to get a better/ bigger round that is still available and good on the wallet. Cause I'm gonna be hunting in a rifle county next year and don't wanna mess around. I will also be using it for coy's. So I don't need a .338 mag either that's gonna turn the dog inside out when shot.

I have a bolt action. 308 and ammo is 30+ for 20 rounds of. 308 for decent stuff. I have found it cheaper online but from a foreign country.

You cant run a 308 upper on an AR15.

 

Take a look at 6.8 SPC. Its a very popular medium game caliber for AR15s. If you want bigger bore, theres always the 458 SOCOM, 50 Beowolf, etc.

What about a 7.62 x 39 .

I like that 450 expensive though at 43 bucks for 20 rounds

6.5 Grendel or .300 Blackout.  I'd say .300 Blackout.

[breethwithme]

I checked the blackout it has the weight but it lacks the fps. The 6.8 mm has a 115 grain bullet and still goes at 2500fps and has a high ft lb of over 1000. I have been looking at a bigger bore upper for a while just wanted to know if anybody has bought a different upper for one of there AR-15's and if they had an opinion

6.5 creedmore is the one I would go with.

6.5 creedmore is the one I would go with.

Plenty of ammo for the CM at $20-30 a box.
