AR-15 caliber list

[MeekAndMild]

How about an AR-15 caliber listing challenge?

I'm going to ask each person who reads the thread to add a post with one single factory caliber which is available for the AR-15 and the trade name of an AR or upper in that caliber.

Please don't repeat calibers that were already mentioned or list a bunch of calibers in your post.

It's OK to count military and civilian calibers as 2 different ones (but please only list one in your post) and its OK to include single shot factory uppers. But no wildcat uppers please unless you know a factory which makes them. For the oddball calibers weblinks would be appreciated.

I'll go first with my favorite:

6.5mm Grendel, rifles made by Alexander Arms.

450 thumper - Bushmaster

[Double Naught Spy]

Beowulf .50, Alexander Arms http://www.alexanderarms.com/beowulf.htm

[globemaster3]

6.8 Remington SPC - Model 1, + lots of others, etc.

[Dezynco]

Here's a couple from SSK industries?

300 Whisper
7mm TCU

Plus several others that are interesting.

[dieselmech]

.308 win

[Arabia]

.308 win
dpms

.308 is an AR10 rifle. The OP wants AR-15 calibers.

.204 Ruger, JP enterprises, among others.

[armedtotheteeth]

uhmm..223/556 NATO.. From Colt. I wonder if anyone thought of that one. :D

[zippy13]

Duhh... .223 Remington

[Forwardassist]

Too many too list. There must be at least three dozen calibers available in the Ar15.

.22LR; Spike's tactical. Maybe a few others.

9mm; RRA, CMMG etc.

[Rant Casey]

458 socom
.50 bmg (bohica etc..)

[bigghoss]

5.45x39mm smith&wesson

[MeekAndMild]

.308 win dpmsOK, for this game we only give credit if you can find a manufacturer of single shot .308 uppers for the AR-15. As Arabia says, the semiauto platform for .308 is the AR-10. The AR-10 has a longer magazine well than the AR-15.

For my next round I'm going to mention .338 Lapua, which is found in a Bohica Arms single shot upper.

[ActivShootr]

DPMS makes a 6.5 Creedmoor.

[Arabia]

DPMS makes a 6.5 Creedmoor

6.5 Creedmoor, .300RUm, .243Win, .338Fed and the .260Rem DPMS uppers are for the AR10, not the AR15. They won't work on a AR-15 lower. We are discussing AR-15 caliber conversion uppers.

Here's another Ar-15 upper
7.62x39mm: DPMS

[VUPDblue]

Olympic Arms

[Forwardassist]

.40S&W & 10mm. Olympic arms.

[armedtotheteeth]

[Mach II Sailor]

.499 LWR - LWRC, the biggest caliber and OAL cartridge for the unmodified lower !!

Damn just saw someone already said this hmmm I dunno looks like most have been covered.

[shaman]

what about the wssm calibers? is that still an ar 15 standard lower?

sorry, i dont know beans about those wssm rounds, i just remember seeing someone makes an ar in the 243wssm. i cant for the life of me remember where i saw it though...

[MeekAndMild]

So far so good. I don't vouch for the accuracy of this list but this is what I counted so far, though some of the entries are difficult to find on the internet. Who has links? We can only count the .308 series and WSSM calibers if you can name a manufacturer. Sorry.

22LR - Spikes Tactical

.223 - Remington- DPMS (one maker added by me as common knowledge- there are probably 50 other makers)

.222 Remington ARs were produced by Colt, and I think there are some other manufacturers that still make them. They evidently are popular in foreign markets where civilians cannot own weapons in "military" calibers.

EDIT:

[Yellowfin]

Anyone selling the 5.45 other than directly from S&W? I'm really wanting one if the price can work for me.

[Barber2678]

AR15 Performance should get the credit on the 6.8 SPC (not 6.8 Remington SPC). Model 1 Sales is low end stuff and has not performed any development.

[globemaster3]

Model 1 is just a manufacturer (or assembler if you rather) of uppers in 6.8 as well as J&T Distributing, CMMG, and a couple others. Who created it? Don't know. I thought the OP was looking for suppliers based on
trade name of an AR or upper in that caliber.

However, to counter Barber's barb (pun intended) 6.8 SPC/6.8 Remington SPC, come on! Google it and what do you find? Even look at the website dedicated to it http://www.68spc.com/ and what's in the title line? 6.8 Remington SPC.
