Big big bore AR ... not 15

[Edwardteach72]

so there is a company that made an AR lower for 300win mag.

Well looks like (i have to read the article a bit more) they took that same platform and built a .458 Winchester Magnum

The Biggest AR Ever: NEMO OMEN .458 Winchester Magnum - Petersen's Hunting

It is no secret I like big-bore rifles. I also like ARs. So far, these two obsessions have been

Yikes!!!!!! I'm not a fan of big recoil anymore, I'd give this one a run though.

I wonder how "soft" (relatively speaking) one could get this beast to shoot.

Being piston driven, I belive with a tunable piston/gas block. And play with the spring and buffer weights

Nemo and Noreen have been making magnum ARs for a while. Noreen calls their model “Bad News.” Nemo calls their model “Omen.” I know Noreen offers a 5% military discount not sure about Nemo though.

Bad News (.338 Lapua Magnum)

Order the Bad News Gen II from Noreen Firearms – a piston-driven, semi-auto .338 Lapua rifle with 26” barrel, match trigger, and upgraded billet receiver. Built to order.

Geez you would think for 6 grand and change they could do a little better than a stock A2 grip!

That looks bad ass and I'd love to have one.

I definitely still want a big bore AR.

450bm is a fun choice and most parts are interchangeable with standard AR15 parts (really just need a barrel and bolt and mag follower, or one of the few 450bm magazines)

That was one I was thinking of building, but don't you also need an upper with an enlarged ejection port? I was thinking 458 socom also.

Yes and no.. people have gotten away with normal uppers, but for more reliable use they recommend using a larger ejection port

The good news is you can open up a standard ar ejection port, or Aero sells their XL (thats what i got) uppers, hell I got one "on sale" because it was a blemish

Dammit Ed now you have me back to plotting and scheming on an AR 10 and what calibers I could run in it.

I, or rather my bank account, talked myself out of building an AR10.

Still thinking about it though. 243 or 7-08

DO IT. You won't regret it.


.450 BM is the big fun AR. Aero makes an upper with an enlarged ejection port. Aero XL works for both .450 & .458 socom.

And the good thing about 450 vs 458 is ammo cost is less and 450 is widely available (well not during ammo shortages) so 450 is more available and cheaper

458 sounds cooler and feeds more reliably and wider range of bullet weights and bullets more designed for rifle speeds

I’ve been looking at the 350 Legend.

 

[ArmedCorgi]

I would just need to build an upper, correct? It's a standard AR lower?

This makes it tempting, though, I have never heard of this brand. New! TRYBE Defense .450 Bushmaster 16-Inch AR-15 Threaded Barrel BARRIFLE16450BSH Color: Black, Finish: Nitride, 23% Off w/ Free Shipping I just cannot believe it's in stock though. Seems like every item on most sites I go to are completely sold out. This panic buying is insane. It's like people just bought anything and everything they could even if they had no use for it or don't know what it is.

You need a 450bm bolt..

Id suggest checking out Tromix (they have some sweet bolt barrel combos) and if you ever venture over to the 450bm or 458socom forums (they are kind of boring and quiet) Tromix is pretty much the best name in the game for big bore AR (mainly barrels and bolts, and iirc the owner has had a hand in the development of the 458socom)

Would the recoil system on the fightlite handle the 458?

 

[Edwardteach72]

Would the recoil system on the fightlite handle the 458?

I would assume so (about to do some digging) since the 458s was also designed to be used with standard ar15 spring and buffer

I’ve been looking at the 350 Legend.

I made one and it is awesome!!!! Very accurate, pleasant to shoot, and lots of bullet options for reloading. Hollow points on a milk jug at 100 yards is pretty cool!

Even more tempting because I was at gander yesterday and they actually had .300 win mag in stock. Just saying coincidence?

Dare I suggest a sign from above. Enough justification to buy in my book.

I am thinking about the BN36 long range in 30-06. Make a nice compliment to my Garand

 

[Jsmegs77]

I just discovered this thread since it popped back up. I’m shopping for something interesting in 30-06 since being gifted some ammo (thanks @Vapor ) and figure I need something to send it out to play.

What could be more uniquely American than the AR in .30-06?

 

[Shoots100]

Here's my bucket list BN36 30-06, that lives in PA now, along with my un neutered M1A loaded stainless.
I was in the process of making it SAFE act compliant, but couldn't bring myself to remove the brake threads after shooting it without the brake.
It has a stout recoil without the brake.
