What caliber AR to build for 3rd one

[BigL]

Have a 6.5 Grendel and 300 blk. What would you build next? Why? I have a stripped lower just can't decide what to build.

[talleywack97]

.223, just cause

[hully1029]

223 - cause that's the original, cheaper, tremendous ammo options

its like owning every gauge shotgun but a 12.

[Outbreaker]

.458 Socom

[Garrett Starks]

.223 for sure.

6.8 spc for hunting. If you don't need another hunting AR. 223/556

223 Wylde. Can be supper accurate and can safely shoot both .223 and 5.56. I have 2 of these already. Now I'm really looking at building a 50 Beowolf. No reason at all but for I'm fascinated all the same.

I was going to 7.62x39. But you have a blackout already and they are close to the same. So I'm going to go with what others have said. 223 Wylde.

Got the same problem.
Been looking at the 6mmAR Turbo and the .224 Valkyrie

I am in the exact same situation you are with the 300 & 6.5. If I didn’t already have a Ruger 204 in a bolt gun I would go that route for sure. I will probably go something large like 458 socom just for fun since I already have the 204.

I’m thinking one in 243 would be fun. Ammo is plentiful and it’s a solid varmint/hog round.

Google THEHIGHROAD and search AR10 243 to read their discussions, opinions. There are disadvantages to the 243 in AR's, but I've always wanted one as well so just going on what I read, not owning one or even firing one for that matter.

308 AR-10 gets my vote. 223 or 458 both have pluses too

[BigL]

thanks everyone. Was leaning on the 5.56/.223 just because ammo is cheap and easy to find so y'all are helping push me that direction.
