We've had some people asking if this will work, which made me look at the pieces more so I decided to buy the ARMS #22 rings, TRC and TRR and try it.  I got the #22 from The Armory here in Scottsdale as I was unsure what height I would need for my scope.  And I got the TRC and TRR from Paul and Wes at MSTN.  Great customer service from both The Armory and MSTN.

The OKO does fit on the TRR.  I decided to go with the 8MOA because my intended use for it would be 20-15 yards and less for 3 gun matches and the 8MOA dot would be faster to use.  It is odd at first but after running around the shop with it some it got to be like using a HUD with both eyes open.

I'm going to go sight in my rifle and test it this weekend...I'm going to use this rifle for the MGM Ironman 3 Gun Match in Idaho the 14th-16th.

Jack,

Don't be a [b]Dick[/b].  You need to remember what works for you doesn't always work for everyone else.

I contemplated getting the high rings, but I wanted to keep the BURDS (Back Up Red Dot Sight [;)] ) as close to the bore as possible.  The high rings made it impractical to use.

The charging handle does clear, but I am getting a tac-latch so it will be easier to use.

The cheek weld seems fine to [b]me[/b]...I'll be the first to say this particular set up works for [b]me[/b], and it may not work well for someone else.  My point to this post was to show people that the OKO would work with the ARMS #22 TRC and TRR.

Actually Jack, the CAV-15 MKI's longer length of pull effected how I would mount the scope rather than on a standard AR15.

When I switch over to the new MKII lowers (A1 Length) I am going to have to move the optics around.

Now that is interesting, I had not considered placing the TRR on the rear ring...I may have to swap it around and try it.

I'm using the PRI big latch it works well.

I'll tell you this; [b]I will not allow any of our team guns to use ARMS #22 mounts ever again[/b]. Because of the ARMS #22 rings, we had 2 guns go down on us in Idaho at the MGM "Iron Man" 3-gun match.

Russell’s gun (pictured above) and my Remington 700 both took a dump. I did not realize that the rings are held together by a $0.05 roll-pin. What bullshit is that! I have a $1300.00 scope held onto my $2500 bolt gun with a set of rings I paid $135.00 for and they are put together with a roll-pin, which means affectively that my Mk 4 scope is being held on my gun by a roll-pin. BULLSHIT! The pin worked out of (or never was installed in) Russell’s guns and on mine, the scope sat too far to one side, so that I had no left wind age. I should have left the Leupold rings on it (which worked just fine). I guess what they say about “If it’s not broke, don’t fix it” is right on the money. I thought I would be “High Speed” if I could pop my scope on and off like they show on the movies.

So lets sum this up…. I paid over $4000 in match fees, ammo and transportation to Idaho and the optics on our guns (thank God we brought back ups) start shifting while we are shooting (about ¼ of the way through the match). So it looks like one of 2 things…Either we are shitty shots or the guns are fucked up. Well being that we shoot matches all over and these people have seen us shoot before (and do well) maybe they start to think that our guns are no good…. Now I’m not only looking like a dork, but the quality of the guns I make is maybe being called into question![b] This is unacceptable, we are there representing a rifle company! [/b]The guns went bang every time we pulled trigger (others did not), but due to a minor part that is touted as being “The Best” we had 2 guns become un-reliable.

From this point forward, no ARMS mounts will be allowed on Team guns where I am paying for the match costs (with the exception of #40 rear sight. The OKO’s don’t break, so it’s just there for looks).

The last stage I shot with my rifle that had the #22 rings they were shifting enough to make my rilfe pattern 6 inches around the targets at 100 yards...when I sighted the rifle in I was shooting 1MOA groups so I knew something was wrong. The throw lever mounts on the receiver were very tight, but the front ring was not connected to the lower throw lever base and it appeared the roll pin was missing or never installed. I later also found that the rear ring had enough play that if the front ring was secured, the rear would still have shifted around.

I still did OK at the match (and had a great time), but I am left sitting here wondering how much better I would have performed if I hadn't shot 3 of the 10 stages before finding out the #22 Rings were defective, and just used my back up rifle from the start. I know I would have performed better had I been able to use my Leupold scope at this match as there were numourous small targets at long ranges that I had trouble seeing without magnification.

Jack,

you are right, we should have checked them out more closely before we used them.  We were trusting them based on ARMS reputation.

Perhaps ARMS recently put out a bad batch of rings.  The 2 sets we purchased were both from the same ARMS authorized retailer, and neither had even close to a press fit on the dovetail.  Without the roll pin in place the dovetail would slide off without any amount of force.  The 3 rings with roll pins are visibly loose and if the rolls pins weren't there they would most likely have come apart as well.

We are returning the ARMS rings to the dealer.  I have a #22TRC and #22TRR with or without an OKO 8W for sale now if anyone is interested e-mail me.
