Oly Arms K22TMUPR

Postby DocH » Thu Aug 09, 2012 5:56 pm

Hi Guys!
Has anybody used the Oly Arms K22TMUPR dedicated .22lr upper?
I was thinking about a RFA from Oly for my K8, but the more I read and research I am thinking that a dedicated .22LR upper may be a better idea, at least from the accuracy standpoint... if I recall correctly, .22LR is .222 in diameter vs the .224 of the .223/5.56.
I called Olympic this afternoon and a very patient Gentleman let me know about the Oly Arms .22lr Upper.... looks Great!!

And how have rim fire adapters worked out in the K8 in people's experience?

I also have a stripped TNW billet lower that I could use to build a dedicated .22LR rifle by adding the Oly Arms K22TMUPR... I really want to stay with the "form factor" of the K8 vs just simply buying a 10-22 etc.

Ideas and thoughts much appreciated!!

Thanks, Ed

I have a ceiner 22 conversion kit.

I will say that it works pretty good through the 223 barrel.

But I will also say that it's not as accurate as one would hope. 60 grain aguila SSS ammo does better for me than regular 38 or 40 grainers. Again, the twist rate of the 223 barrel is all wrong for 22LR ammo too.

So if you're wanting something with more decent accuracy, I think you're on the right track looking for a 22LR upper.

Although, I would probably personally look at the CMMG 22 upper instead because they use regular black dog 22 mags that are available and more affordable at other places too, and the Olympic uses a "special" BD magazine.

I have not … but I like what I see in the OA® Catalogs

you are correct; and one of my OA® RFA Kits is for my 5.45x39mm aka the .221R barrel, and it shoots line groups.

I’ve never used my RFA in a K8 yet, but it does well in an alphabet carbine.

sounds like a plan to me …

I shoot more .22 LR than everything else combined. I have no experience with the .22 upper from Oly, but I do have the RFA and it's accurate enough out to 50 yds for my purposes. Plus I can drop it in one of my rifles, or put in the kids' rifle, and they can train on their own. It's just more flexible for me, but it doesn't make a tack driver by any stretch. If you want accuracy, I suggest the dedicated upper.

A K22 upper is on my short list of fun things to have. I'll get mine threaded as if I get blessed with this new property my wife and I have an offer on, I'll have plenty of opportunity to shoot little critters out the back door and off the back porch. I'd like to have a suppressor for that bit of rodent control. I have seen them in action and they shoot really nicely. Just have to save my pennies.

Thanks for the info!
What twist rate is Your barrel, if I might ask?

My Wife really enjoys shooting as well... Maybe having 2 MSR's at the range would be even better!!

Here's hoping that Your offer on the property works out!!
I DO miss the NW... Have not seen My Orygun for about 3 years.....

I spent many years growing up on a 1300 acre Ranch about 7 miles west of Goldendale, WA. and REALLY miss it. About 300 acres was in Wheat and Hay, and cattle ran on the rest. I always had at least a .22lr with me and various other types/calibers were enjoyed as well.
I moved from Hood River County, OR to Orange County NY about 12 years ago, and my favorite range is just across the border in Pike County, PA.
This really is Nice Country in this part of the NY/NJ/PA "Tri-State area", and The Lady I moved out to marry is Most Excellent!!
So, all I need is to get Out West to see Folks now and then!!

Yes, the cost savings of .22lr would be a Huge help... I have Grand Dreams of MAYBE trying some form of competition with My K8 so I want to be able to do LOTS of shooting...practice, practice, practice,!!

Any thoughts on the best place to get the best deal on a Oly K22TMUPR?

Thanks,
Ed

Re: Oly Arms K22TMUPR Update!

Postby DocH » Fri Aug 17, 2012 12:24 am

Well, after some more research and thought I have decided, with Welcome input from My wife ( who hits the range with me almost every time!), to go ahead and get a K22 Rimfire Target Match .22LR Rimfire Target Match Upper Receiver to 1st add to my Oly Arms K8.

I have this "Dream" of possibly becoming proficient enough to try my hand at competing with my K8, and the added precision of the dedicated .22lr upper receiver vs a .22lr "conversion assembly" replacing only the bolt carrier group on the K8, will be well worth the additional cost of the complete upper receiver-barrel assembly IMHO.

So, now to just find the K22 Upper!!
I have been surprised at how scarce they seem to be... I have checked in my neck of the woods ( The Tri-state-area where NY-PA-NJ meet on the map) and nobody has one.
But, I will persevere!!
And once I get it to the range, I have this feeling that I am going to have a blast spreading the word around the various Forums and Groups how it works out.
With the cost of center-fire ammo, this upper should pay for itself soon.

Will update as things progress,
Ed
