308 Arrow

[TreeKiller]

Now that you have beaten up the Nosler 25 what are your thoughts on this one?

Not my cup of tea, but what would be the difference in it and an AR 10?

[MOcaster]

From what I understand, it is built in an AR-15. It is like a fat 300 blackout. It is over 600 fps faster than the blackout with a 110 grain bullet.

[Love Life]

Looks neat, and great way to add some stank to the platform.

[starmac]

Forgive my nonknowledge of AR's, but is there an advantage for having a 308 AR15 over the AR10, weight maybe?

[dtknowles]

Ding, ding, ding. the point exactly. AR-15 is already heavy enough. I think a 6.5mm platform is better but between 6.5mm and 8 mm is the sweet spot and I like light so 6.5 is what I would look for. How hard can you push the AR-15. I think the Magazine size it the limiting engineering issue. So, you start tradeing mag capacity vs. terminal ballistics and pick a parent cartridge. In an AR-15 I think that the largest parent you can double stack in the Magazine is the Russian diameter. Eliminate some of the taper and neck to 6.5mm and there you go. Heavy bullets will have to be seated deep in the case to keep the OAL in Magazine limits. Bullets with long ogives will not work, that sucks because we picked 6.5mm with a fast twist for those high BC bullets so you mind as well move up to 7mm and a slower twist for the same bullet weight and with the large bore you can get a little more umph out of the case capacity. Best yet how about a 7.62x39 Ackley Improved. It would straighten out the magazine and add minor case volume and still fire factory ammo if only a couple rounds at a time. I think you could run it at higher pressure than the Russian round that with the added case volume and superperformce powders :-) you could beat the .223 all to brimstone.

Something I wouldn`t consider getting. Another "made by Mattel" clone.Robert

[JeffinNZ]

Ballistics look like .300 Savage.

Ballistics look like .300 Savage.

I don't think I would be trading my old 300 savage for one . not in this lifetime anyway. lol

[dbosman]

Can someone remind me why the .300 Blackout is superior to the .30/.223?
I'm at work and can't look up the ballistics in a manual right now.

Probably head space security. ... felix

30-223 required modification to the mags in order to load a full stack and have it feed properly.

[Adam10mm]

Yup. 300BLK runs smooth with unmodified magazines. 30-223 is good for bolt actions, but not for the AR rifles due to the magazines.

[dbosman]

Ah, thanks.
I wonder what the wildcat cartridge guys from the 50s and 60s would think of some of today's cartridges. (Rhetorical question.)

[DCM]

Strange how they omit any knowledge of the 300 OSSM that exceeds 30-06 ballistics in an AR-15 platform.

[Garyshome]

Love to have an AR in 7.62x54 [cheap ammo!]

There website leaves more questions than answers.

What's the parent case of this 308 Arrow round.
How does this round differ from the 30 Remington AR?

Appears they offer rifles in 6x45mm. Which would be more my taste.

[hicard]

I have one of them and really like it.

I do not think that there is a parent case.Can only get ammo and cases from them or Hornady. No digging could find the drawing of the case

[dbosman]

It uses Hornady Shellholder #6 (38 Special, 357 Magnum, 7.62x39mm)

[bhn22]

All we need is an AR chambered in something we can't get the parent cases for.

Wonder how close it is to what you'd get with a 7.62 x 39mm Ackley 30 degree shoulder?
Or the 6.5mm Grendel necked up to 308? Which is a blown out and necked down 7.62x39mm from what I gather.
After all there are a limited number of variations on a wheel.

[Blammer]

I suspect the uppers will have to be custom to accomodate the 'fatter' bolt head and carrier group for the 30 cal platform.

lets see, custom gun, custom ammo, custom brass, custom magazine.... and a whole lotta money to make it work. Naa I'll pass, and keep my 25-223 and my 25 WSSM AR. :)
