Next AR build: 300BLK or 22lr ?

.223/5.56mm

If it was my choice to make I would lean toward the dedicated .22 upper just for the added benefits of LOTS of cheap training on the AR platform over the fun and novelty of the 300 BLK. Don't get me wrong-I do like the 300 BLK, so I can understand why you're torn. It's just tough to justify IMO.

I voted .22 but that's what works for me. I have two dedicated .22 uppers. Those two choices are 180 degrees from each other. If I could have a can here in VT I would get the .300AAC w/o the can it doesn't make as much sense to me.

I voted .22.

But don't build it, buy what works. An M&P 15-22.

I've already have found its nice to have a mini-me rifle for practice.....cheap practice.

[usmcvet]

Well I guesse I have three. My son has a 15-22 and I have two CMMG uppers. I don't like how light the 15-22 is. But it is a very cool gun. The mags have been impossible to buy lately.

There's ways to add weight.

There's ways to add weight.

Absolutely. I use my .22 uppers on my SBR's, another reason the S&W wasn't right for me.

What would be the intended use for the 300BLK? I see it as having a very narrow niche of usefulness.

Yep, the same narrow niche as it's ballistic twin, the 7.62x39

If you are referring to 7.62x39 in an AR I agree.

That's what AK's are for.

At least the 7.62x39 isn't a specialty round.
