22-250 AR

Postby JJ on Sat Sep 24, 2011 8:51 am

This would be a blast for predator hunting, but in a prairie dogs fields I would waste a barrel in minutes.

I stole this from a post by Olympic Arms on another forum.

Coming October 1st 2011 the UMAR (Ultimate Magnum AR) will be released to the public.

It will feature:
A 24” match grade bull barrel made from 416 stainless steel
Predator Rifle length Handguard
FIRSH (rail) mounted sling swivel
Gas Block with rail
ERGO Tactical deluxe pistol grip
A2 stock
Proprietary 5 round caliber specific magazine
Proprietary lower receiver
Twist Rates .22-250 REM (1x14) .223 WSSM (1x14) .243 WSSM (1x10) .25 WSSM (1x10) .300 OSSM (1x12)


This proprietary lower receiver design has an elongated magazine well to fit the larger 22-250 round as well as a .300 OSSM with a 168 grain bullet.

The top lower is a standard magazine well and the bottom is the UMAR Lower.
The UMAR lower receiver will accept MIL Spec upper receivers and standard magazines. The bolt catch hole has been threaded so you can easily change out the bolt catch when switching from a 22-250 or WSSM/OSSM to 5.56 NATO, 6.8 SPC, etc.

This will MSRP at $1428.70

That would cool! :exactly:
Even better with the correct rings for the scope. A muzzle brake to boot would be nice to watch what you shot at.

Why not just get an AR-10 with a 22-250 upper?

Waste a barrel in minutes? Are 22-250 known to burn up barrels in a hurry when they get hot?

My only experience with the cartridge involved a heavy barreled bolt action coyote gun.

I think for the money i am best off sticking with my .223 for p-dogs.

AR10 platform throw a heavy barrel and JP heat sink on it, and it will cut down on the barrel temp.

Should still be good for 5k rounds. Probably more than anyone here would shoot.

Yup 22-250 would not be my choice in a high volume auto. If you have a barrel built to handle 75gr bullets in .223 you are more than equiped to deal with those longer ranges and slightly bigger beasts.

Most guys with 22-250's are not looking to shoot heavy bullets, they are lookin for speed and explosive hits, I've never fired anything over 40gr out of my pair, 4400 fps is sure fun on little critters, red mist.



As far are bbl life, it's one of the worst out there, 1-1.5k before she's done, still might hold 1moa or so for a bit after that but the throat will be gone as will be the first couple inches of rifling, if it was a 1/4moa shooter it won't be for long, but it's all about the fun you have up till that point :D
