if you could have an AR made in any caliber to be shoulder fired... what would it be?

I would love an AR platform in a 338win mag or a 300 win mag. It seems lately even in accessories, I am looking at parts saying " if it was only a little more like this... or like that..."

An AR10 gone to the next step and made into a belted magnum. it would be a dream come true.

Yes I am also a recoil junkie.

.338 or .300 you get into long actions. I think those would be sorta heavy and awkward in a true AR platform. Maybe one of the WSSM's. But I bet you'd burn through barrels at an alarming rate. Anyway, I've got a Garand that satisfies my semi-auto recoil craving!

An AR in .357 Maximum.

Just sayin'.

AR16 7.62 NATO






Hey you said AR but you didn't specify which one

this; but I'd settle for one in .357 that actually worked

I agree. Maybe one day.

.17 HMR!!!

Sanely regulated and priced F/A ARs. In 458 socom.

F/A 458 socom? Holy shit that'd get expensive fast

I'm looking hard at a .308, other than that it's 5.56

if ammo were to ever become easily available and affordable I'd highly consider the 6.8

+1 on the 300 win mag.  I would like one in .30-06, too...always loved the BAR...will never be able to afford one.

I would like a Colt/Umarex .22 LR that actually worked... Hey you said fantasy rifle.

They already make a 338 Lapua Mag AR.

I just want a happy switch for 3 round burst on my 6921

Always wanted an AR in .30-30.


Don't know how it would work because of the design of the case, but it would be awesome.

An electro magnetic AR that fires 3mm depleted uranium rounds at about 40,000mph.

Maybe in the next 200 years

I'll take mine with a Skull and Bones logo, please.

My fantasy rifle would involve a can, an IR laser and a PVS14.

It wouldstill be in 5.56

i own my fantasy rifle.... why would i build anything else?

My fantasy rifle is whatever Chris Costa uses in any given Magpul video.

Oh hell yes

Why do you want such a huge caliber in a semi-auto?  With that amount of recoil it would seem pointless to have it in semi...  I guess what I'm getting at is that there would be no apparent advantage to a AR style weapon in those calibers compared to a bolt gun.  Could you imagine attempting a double-tap with a .338 win mag?  My idea of a fantasy gun is one that does something better than anything available, and a semi-auto .338 win mag couldn't do better than a .338 bolt gun.

So that's my question, your dream gun is a huge magnum AR.  Why?

10mm Caseless Explosive Tipped Light Armor Piercing

22-250 Rem or .22 WMR

22LR is cool but 22WMR would be cooler!

54r best bang for your buck

How about the WSM family.  .325, .300. and .270 uppers.

DPMS made a 300 RSAUM gun, and Accuracy Systems builds a lot of custom caliber AR's, including belted magnums like the 450 Marlin.

There is always the "Quasi-Ar" design of the "Bad News Semi Auto" which comes in .300 Win Mag, or in .338 Lapua it is available here
Although for a precision rifle, I had much rather have a magazine fed or even single-shot bolt-gun.

If you are wanting a .338 Win Mag, the only option I know of is to get a Browning BAR, and accessorize it however you desire. Most accessories for it would have to be custom one-offs though and the price would be preventative. I have heard rumors of them being converted into .416 Taylor, which despite commercial ammunition not being available, it would make for a good game rifle.

McCann Industries converted M1 Garand rifles into .458 Win Mag, but I think they no longer perform the conversions.

If size is not a problem then the 17 lb Vigilance Rifles offers a semi-automatic 5-shot rifle in .338 Lapua, .375 Cheytac, .408 Cheytac, or .505 Gibbs. Not by any means handy, but a SA none-the-less. They are available here

The Bad News by "Only Long Range . com" seem to be the closest rendition of an AR, when it comes to big-bore semi-auto rifles. If I need a long range, I will stick to my Barrett. If I need big-bore I will stick to a double-rifle. But for a true hunting AR-15 or AR-10 design, there is a number of good choices for a hunting rifle. For the short action (AR-15) I prefer the .50 Beowulf as a hunting companion. I know it will take anything I ask of it, especially when loaded with my 350 grain Solid Brass Spitzer rounds marketed as a "Dangerous Game Load". They certainly pack a wallop on most North American game, and provide for quick follow-up shots. Likewise, similar concepts including .458 SOCOM, and .450 Bushmaster provide similar muscle to bring game down inside of 150 yards.

Perhaps the best (In My Opinion) hunting style AR-10 chambering is the .338 Federal. I have used this little cartridge pretty extensively and have nothing but good results from it.  It recoils only slightly more than the .308 but packs a larger diameter and heavier bullet. A 210 grain bullet at 2630 feet-per-second with a .338" diameter will ruin just about any animals day, provided you do your part. In a pinch brass can be made from .308 brass, and projectiles come in many different flavors and toppings. Loaded in the AR-10 , I would feel confident to hunt any game any in North America, including having protection against the big bears. But this is just my opinion and yours may vary.

Hey!  Isn't that last gun the one John Wayne breaks against the tree in Green Berets??

Yup!!!!

I would want an AR in either 7.62x54R or .40 cal so that I only have to buy 1 or 2 types of ammo.

Why not? I love recoil.





There are a couple companies making 40SW AR15's
