AR-15 OPTIONS

turkn8r1 · 05-07-2008, 09:34 PM

OK. I have over 60 firearms but have never been interestead in owning a "BLACK RIFLE". With the upcomming election I am worrying about restrictions on the horrizon. It could be nothing but I have started to accumulate lowers. I have 8 so far and am trying to put together 25 AR-15 lowers by the first of the year. I am going to try to fit at least 1 AR-10 in there and about 7 to 10 AR-10 lowers in there somewhere. So now that I have rambled on here is the question. What are all the calibers that I can build uppers for the AR-15 lowers? If there are more than 25 then I would like to know. I want to include pistol calibers. I know about some calibers already. .22 long rifle/ .17 HM2/ .204/ 5.56-.223/ .223, .243, .25 wssm/ 7.62X39/ 6.5 grendel/ 6.8 rem spc/ 9mm/ 40sw/ .45acp/ .50 beuwolf. I haven't seen others mentioned but know there are more.

I would guess you mean uppers that will still be auto-loading? because I have seen crazy looking uppers with 30-06 and even .50 bmg in a bolt action that pin onto a lower. other than that you about covered them all but you missed .308 or 7.62x51NATO.

I think you near covered it... I'd love to have an AR in .45acp

I know what I'm going to do with one of my AR's, but the second one I'm stuck on. C Products is now shipping 30 mags for a 7.62x39 build. I'm also thinking of building one that uses un-modified Uzi mags.

you forgot the 5.45x39... ammo is CHEAP!

Someone also makes it in 7.62x25, however I've yet to see one.

sell33 · 05-08-2008, 10:46 AM

isn't there a 458 socom upper?

at4rxj · 05-08-2008, 01:47 PM

Yes... there are many more also, but not with "commercially available" ammo... the grendel, beowulf, 458 socom, and a few others are questionable as far as that goes.

I saw one in the 5.7x28 round (fn magazines on the top, ejects through the magwell)

There's 6x45, 6.5/7/300/357 wssm, and a bunch others that are "wildcats" or stuff you'd have to handload for. You pretty much covered everything that has ammo you can buy as far as I can tell. There's probably a few others.

Deersniper · 05-08-2008, 04:10 PM

The 6.5 Grendel upper will fit an AR platform, and it is accurate, and if you reload, it would be my choice.

turkn8r1 · 05-08-2008, 06:02 PM

Thanks for the input folks. I intend to build one in each caliber. I do reload but am not interested in wildcatting. I was wondering if there are any uppers in .22 mag, .17HMR, and .30 carcine. Is the .300 whisper for an AR-15 lower or an AR-10 lower?

103M 95G · 05-08-2008, 06:20 PM

6X45

sell33 · 05-08-2008, 06:34 PM

I didn't even know there was a difference in lowers...i suppose long action shells wouldn't eject on a short action upper?

turkn8r1 · 05-08-2008, 08:23 PM

AS far as I can tell it has to do with the magazine well and maybe a little longer though I am not sure about that part. I do know that the AR-10 magazine well is larger than the AR-15. Other than that I don't know that there are any other differences. I only want to build semi auto rifles so as far as I can tell there are about 20 different possabilities . I figure that 25 lowers should be plenty and leave a couple extra.
