Number of calibers the AR-15 can be built into?

[LeadSled1]

.17 WSM is a pretty neat one but holy crap are the uppers expensive.

It's the shiny new thing....it'll come down after the new wears off a bit.

Hahahhaha without reading the whole thread I saw your post in the preview. It lead me to google 308 Ragnar

how about .25-45 sharps

Yes....I have done a lot of reading on this caliber. Talked to a former local shop owner about it, and he said after shooting it, it is ****. I was looking at the parts for a build and it isnt too hateful. Would love to have one for deer hunting out west.

Greg, not counting wildcat cartridges. There's a lot of options, and these are the ones off the top of my head....

.22lr
.204
.223/5.56
300blk
7.62x40 hrt
7.62x39
6.8spc
6.5grendel
.458 socom
.50 beo
9mm
.45acp

Add 7.62x51NATO to the list.

Darn if the 25-45Sharps doesn't sound just like thr older .25Copperhead .

And even with factory ctgs being criteria add : 10mm , .45acp , WSSM in .223 , .243, 257 , .35 for sure , probably the inbetween ones also , but confirm with DTI .

And in the big bores , before there was the Beowoluf , there were AR's in .50AE . Fired one ( way cool) , almost bought one , but didn't have the cashflow at the time my friend was selling.

But not in an AR-15 lower.

I kept my 'off the top of my head' list to calibers that'll fit within the limitations of the AR-15 lower.

There was also the short-lived .499 LW, which was a brain-child of the founder of LWRC - and I'd suspect what may have given Bill Alexander a starting point for the .50Beo.

Don't forget 375 Reaper.

6mm HAGAR. For now, it is handload only but Creedmoor Sports has dies and factory brass available. High velocity, low recoil and outstanding accuracy!
