Who here has an AR style rifle chambered in a cal. other than 223/5.56 and what do you have. I have on in 7.62x39 and I want one in .45acp or .45 super.
 
22lr, 5.56(several) 9mm, 7.62x39 pistol and rifle, 300 BO sbr and rifle, 450 bushmaster pistol and rifle, 458 Socom sbr and rifle, 50 Beowulf, 6.5 Grendel, 350 Legend.
I had a CMMG in 45 acp and was less than thrilled. It liked to jam a lot.

As for AR10 platform, 308, 6.5 Creedmoor, 8.6 Blackout so far.
 
For the AR rifle/ pistol the only round aside from 5.56 I have now is a 9mm and the only other cartridge I'm seriously considering is 22lr.

I jumped into 300blk about ten years ago (in a bolt action) and honestly I'm a bit disappointed in the round. I sometimes think I'd like to get into 6.5 Grendel but I barely shoot what I have now.
 
Got a few in 6.5 Grendel, prolly my favorite ar round

What do you not like about it? I’m thinking about building a supressed 8-10” for around the house.

Get a CMMG conversion kit. They’re awesome and a great way to do close range practice or plinking for cheap
 
BCA upper in 762x39 that was an excellent shooter. CMMG 22lr conversion that shot well even with the fast twist barrel. It was a cheep blast with a binary trigger.
 
I have some in .300blk, 6.5 Grendel, 9mm, and .22lr.
 
I have a 22lr that started out as one of those all plastic uppers. I took the barrel off and put it in a real upper with free floated hand guard. Couple 7.62x39 rifles and a pistol in same. Always wanted a 6.8 as it’s a great deer round. Just never got around to it
 
.224 Valkyrie from Compass Lake Engineering. Less than 1/2 MOA rifle, but the downside is you better reload. It was made to kill varmints or shoot steel past 1,000 yards. It doesn’t kick any more than a .30 M-1 Carbine. Better buy a good barrel with 1/6.5 twist, or accuracy suffers with heavier bullets.
Lot of internet lore, many idiots complaining, who failed to take the bullet weight and needed twist rate into account.
Unfortunately, Compass Lake no longer serves the public market, since they went to servicing only corporate entities.
Ok. Here is mine, now show me yours🤤IMG_0385.jpegIMG_0387.jpegIMG_0393.jpegIMG_0391.jpegIMG_0394.jpegIMG_0395.jpeg

300BLK
6.8
50 Beowulf
9mm
.45 ACP
5.7x28
.410
22LR (if an M&P 15-22 counts as “AR style rifle)
 
If we’re talking non-standard lowers, then 9mm and .308 s as well.
 
9mm "Colt mags", 300 BO, not really a fan of the AR platform, "Assembled" most of mine on Sendra lowers decades ago so the fad wore out long ago, it is what it is, more of a M1A, Garand, Barrett 50 person if you do semi. and others, 300 BO was a late to the party person, took the sit back and watch approach.
But that's off topic.

Oh yeah..from the past.. a box full of them RIA had to dump em, because Colt at that time was the "only" one, was sue n everybody have some marked "M15, XM15" Assembled a few XM177 clones, Colt A1 uppers, Colt Chrome Bolt carriers. So I was assembling them long, long ago. Friends owned a sbop back then, they freaked out when I said "order a bunch"
Those lowers were Like real cheap.

I had wanted to hunt suppressed and had misconceptions about how good a big heavy for bore cast bullet would perform at subsonic speed. Back before 300blk was a factory option I built a 45acp barrel for my H&R single shot and have a 357 barrel. I had played fairly extensively with suppressed pistol rounds and mistakenly thought the longer thirty caliber would behave a lot differently. It really doesn't. For dedicated suppressed shooting it's hard to beat the medium bore. 38/357/9mm is a sweet spot. None of them are particularly good on live targets. I eventually figured out that suppressed hunting is ok on small stuff like foxes and chicken coop raiders but really if I'm going hunting there are good reasons why rifle rounds are loud.

The 300blk does best on game with supersonic ammo. The best game rounds in 300blk are almost as good as 30-30.

So I'm no longer trying to make it do anything it's not doing. I did. I learned. And I spent a ton of money along the way.

As for an around the house AR it might do pretty well for what you want to do, it just didn't do what I thought it would. In my defense, back when it first came out there was a lot of people buying and selling a lot of hype. A decade plus later you have more available to work with. Also, a 300blk will almost always be more reliable than a pistol caliber AR because it's gas operated and a bottle neck cartridge. It's good for what it's good for, and it sounds like what you want to do is more like what it's good for. For defense and small animals in an auto loader with reasonable suppression it's good. I put an expensive can on an expensive bolt action and tried what AAC was saying it was good for in the early 2000s. It sucks for that.

I have one of those and you're right they are a great little gizmo. I like it enough that I think I want a dedicated 22lr AR. The drop in kit has been pretty reliable but the accuracy isn't really good. Cool for close up plinking but not enough for something like an Appleseed shoot or anything like that. A dedicated upper (or possibly dedicated rifle) will have a real chamber and will be much more accurate and therefore more fun.
 
Multiple ar’s in 22, 9 and .40 (Rock River)

There was a time I thought I wanted one in. 45; however; have two long-time buddies who both have had .45acp ar’s FOR DECADES.

Between ammo cost & availability, those ar’s never get shot

Ammo cost and availability are main reasons I went with 9mm and .40 (and the .40 will be sold once my half pallet remaining of that ammo is gone …)

Which brings up another interesting factor and that is mags for whatever “other” caliber one is considering. (Anyone tried finding mags for a Rock River .40 ar anytime in the last 10 years? A collector tells me the extra RR .40 cal mags I have are worth more than the rifle … which is good because I will never forget (or forgive) Rock River for the anti-2A mindset at their little shop in IL which I had to fight with them to overcome, in order to lay in a multiple lifetime supply of mags …)

Interesting take.
I had forgot about the 300 Whisper pre 300 BO, guess thats why the 300 BO was really nothing to me. Had a Whisper barrel for the TC Contender so when AAC came out with the 300 BO was like meh, really nothing new, just a few changes to the specs and a lot of marketing.. hype..etc. followed it, and waited..still no big deal, waited for things to get cheap(er) assembled one on the AR platform...and....
Still waiting for the "wow factor" just an opinion, it has its place. Its nice to have choices


To add I remember when AAC brought the 300 BO ..out ..people were saying basically its the 300 Whisper nothing more, only thing was the Whisper was a proprietary round for the lack of words, AAC market it to the military, throw in a dash a hype, a ton of marketing and done. H110 was the powder, so it became scarce. Heavy bullets, suppressed, etc.

Sorry off topic again
