AR-15 build 22 dasher / 22BR

[Varmiter71]

I am looking at building an AR-15 for long range fun.
I am looking at a 22 dasher but might consider a 22 BR.
I would shoot 75 -88 gr. Bullets mostly hornady (I live in Grand Island Ne.)
I am not wanting to turn necks.
And I have a UMAR lower.
I would like to here some advice and where to get components for the build.
Thanks Shawn

Check the 224 valkyrie, will more than do what you want and factory ammo to boot

I would rather do the 22 Grendel.
And I had considered the 22 Grendel until I fell into this 22-250 AR-15 but it is limited to the lighter bullets. That is why I was thinking about the dasher since I already had a 308 bolt face.
And it would beat the Grendel and the valkyrie.
I already have one in 223 that shoots lights out at 600

6.5 Grendel.

I have a 6.5 grendel in a cz bolt action and a 6.5 creedmoor in a savage grs

I know this thread is a few years old, but a 22 GT would be awesome one a UMAR lower. Really sad they don't make them anymore because I would love to build one of these!!

What is the 22 GT

I located my barrel nut and bolt again and started me thinking about the project again.
So the gunsmith and myself looked into what it would take to convert a standard ar-15 into a umar on and it doesn't look like it would be extremely difficult. The problem is who is making a barrel nut and bolt for one.
Then there is the problem of the magazine. We haven't taken a magazine apart yet to see what it would take to duplicate it.

 

[Varmiter71]

I was playing around with the umar magazine and I believe that a non-tipped bullet up to 80 grains would work in it with a 22-250 or 22 creedmoor if it had a faster twist barrel.

Heard some good things on the 22 GT. I like it!!!!
It's a barrel burner, but all these short, fat, fast cartridges are.

I like the 22 ARC for an AR-15 platform. Haven't built one yet, but I have built a 6 ARC and it is fun!

 

[vedauvoo]

...oh, you have an AR-10 platform already.

 

[Varmiter71]

I have an AR-10 in 22 creedmoor
And a 22-250 in an AR-15 (Olympic Arms UMAR)
I also have a barrel nut and bolt for a UMAR that I want to use for a 22 dasher
