Which AR to build next?

[Lennyjoe]

Have a couple lowers in the safe and am contemplating what to build next. Have AR's in .223 (x2), 6.8, 7.62x39 and .300 AAC Blackout with a suppressor. I've built all of the ones I have and several others for friends so building AR's is a piece of cake.

I am an avid reloader so no worries about ammo availability so I'm thinking of one in a 6.5 Grendel.

What other calibers may you suggest? I have boo koo ammo in all the ones listed above and was thinking about another in 6.8 SPC.

Suggestions?

6.5G is great, but IMO if you already have a 6.8 and ammo, then go with another 6.8

My other suggestions are the larger calibers like 458Socom or 50Beowulf.

You already have one NFA item...why not go the way of a SBR in your chosen caliber?

Build a 9mm with A 20in barrel and fixed stock

6mm Hagar. It uses the same brass as the 6.8 but it's resized for 6mm. 6mm bullets are plentiful and offer a great selection.

I have a 6.5 Grendel and bought a 6mm AR Turbo which uses Grendel brass resized for 6mm. If I'd started with a 6.8 I'd have gone with the Hagar.

why not stick with 5.56 and build a varmint/bull barrel/long range rig?

Avid reloader with a solid foundation of existing AR chamberings? Time for something a little more exotic.

7.62x39 necked to 6mm.
A 6.5x47 trimmed and sized to fire a 130 gr .277 @ 2750 from a 20" barrel.
.338 Spectre
and so on.

6.5 grendel is on my wishlist. The 300blks is cool, but its short range turns me off. The 6.8 is a good choice, but the 6.5 has further reach.

Have you seen the uppers chambered in .410? I'd love to get my hands on one just for fun, plus it's pretty unique!
