I was looking at going 6.5 Grendel for this SNEK build. Something different than 5.56. How prices really jump when you step outside the mainstream eh?

You're telling me.... I have been quietly eyeballing some stuff and yeah... it makes me wonder what I really want to do and which calibers I want to commit to.

Yeah.... Either this is going to go on the back burner or I'll be doing it in .22. I've been wanting a .22 AR for some time now, too. We shall see.

Depends what you want to do. These days I prefer calibers that share the same bolt and mags.

Me too but .300 in a 16" barrel seems pointless. There are other calibers too but they're all pricey to play with.

In CO, a 300blk gets you in the woods at least. And with an AR pistol it's legal to hunt with the shorter barrel (but not SBR). I take it you're against the pistol approach.

The problem is, this is a serial-less lower so no pistola, already though about a .300 pistol. Ha

I've never heard a serial-less lower can't be a pistol...!! Do you have a document on that?

That would suck for all the 1911 80% folks.

Sorry, I live in Michigan. Pistols have to have a serial number.

Good to know. Okay, back to a pinned 14.5" 300 blackout. Haha

Actually, for a more common round that justifies a longer barrel, 6.8 may be the thing.

That's what I'm looking at mostly. 6.5 or 6.8.

But...why? The perception is that "because I can, I must", regarding 300BLK and barrel length. In a 16" weapon, the solid BC of the 300BLK projectiles turns it into a .30-30 around 100-150 yards or so. Before that, it's like some of the "LITE" .30-30 loads. It's very viable and sensible.

When you form 4 it, you can give it any serial you want. Just have it engraved first because they'll want photos with it not being a previously sold product.

The point being from me, I don't want to serialize it. :)

I COULD SBR my SMOS and throw a .300 barrel on it.

The .300 performs OK with supersonic ammo. Basically a AR 30/30. But honestly unless you are looking for a SBR shooting subs the 6.8SPC walks all over the BO at supersonic performance. Not a fan of the Grendel. Chamber pressures are far too high for the case dimensions. By time you remove enough material from the bolt to fit the cartridge the structural integrity is gone. Lots of band aids as a fix but ultimately the cartridge is handicapped by the required lighter loads to keep the bolt in tact. The case diameter would be much better served with a .308 sized bolt face.

That reminds me I have a 6.8spc and over a thousand cases I have been neglecting for several years .

Much rather go Lg. frame/6.5 Creedmoor, as it's prized for its long range terminal ballistics, but I can't justify that caliber in an AR format, and I really can't justify the caliber for lack of super long shooting distances.

A friend and I are planning an Elk trip to Canada and he's taking his Christensen in 6.5 CM. I hope to witness the kill shot of the year.

He is asking about a caliber for a lower he already has so why even bring up the 6.5CM?

The Creedmoor performs like it was purpose built for a .308 patterned AR anyway.

And I will be on a elk hunt in 8 days with either a .338 Federal or a 6.5CM, both in a suppressed AR format.

Next rifle will be a something larger, .308, ect.

Just not in the cards at the moment.

Pyzik, 6.5 G gives you better ballistics than a .308 when you get out there, so if you're planning on any long distance stuff, that's the ticket. If you're staying around 3-400 yards, I guess 6.8 Specialsnowflake is okay. You can also get plinking ammo for the 6.5G for about $150 for 500.

I found this blog and I am loving it. This is some good stuff. Check out this link though...I don't think you can go wrong with 6mm or 6.5 either or.

I am thinking that the bolt gun I have in mind might come in of those two calibers.

Check out the 6.8 SPC. The Federal XM68GD (Gold Dot) were going for $10-$13 a box and even cheaper if you could get the factory seconds/blems. It's an excellent all-around round. I used it to harvest a deer last year and what I'll be taking to the field again this year. If you hand-load you can get much better performance as the factory loads generally don't live up to the full potential of the round due the mishandling of the SAAMI spec by Remington. The downside is you do need dedicated bolt and mags but the pay off is an extra 100-200 yards over the 300 BLK
