Rock River Bullseye Rib

Has anyone tried one of these yet? I am thinking of putting one on my ball gun.

Got one for my Rock River Wadgun.  Haven't mounted it yet.  
Not sure that the rib would be allowed for EIC matches.  
The new CMP 2015 rules don't appear to specifically address ribs and it remains a rib even with iron sights.  
The slots to mount a scope make it suspicious at best to the match director.

Being distinguished, I'm not to concerned with EIC matches anymore. I am looking to practice with a dot most of the time and still get some practice with the irons. Wife won't buy me a wad gun, this might be the next best thing.

If you're going to shoot full power ball loads I would not recommend it.  The rib is steel and is quite heavy.  The recoil force of a ball gun would probably sheer the screws in short order.  It can be lightened, but again I wouldn't recommend it for full power loads.

I agree..if fact I abandoned the use of # 6 screws decades ago...#8X40 Torx heads are the way to go...5 each...in a standard rib..

I have one- not installed yet - it is HEAVY.    - - I like the AL Marvel ribs w/ built in brass deflector-no iron sights. --

Well maybe i will just have an aluminum base put on on, and use it as a wad gun then. I do have another gun i can shoot ball and 185 SWC out of.

I relieved the Al Marvel rail so I could mount the rail over them without adjusting my zero.  It is easy to switch back and forth from dot to iron sights.

  I have one on a wad gun and am very happy with it.  Probably not a good idea with hardball.

With the new regulations/de-regulations will there really be much difference between wad and hardball loads? Just a thought.

Rob do you take the base off to shoot irons?

Oldmaster that was kind of my line of thinking. With the new lack of hardball requirement for service pistol I could utilize one gun for practice with dot and irons.

I was also looking at the Aimtech mount, but am leery of how the pin going through the hammer will affect the trigger pull.

79fordext,

I do take the rib off to shoot irons.

I have also used the aimtech mount in the past.  I made sure that my grip bushings fit tightly into the aimtech mount and never used those other pins.  I had good performance out of that setup--it holds zero as long as the bushings fit tightly.

New rules do not allow heavy rails such are Bomar Rib. I have a rock rib works great but I had to take a little off the front sight. 

What I would do is get some Picatiny Rail from Brownells and have smith set pads on the slide where you need them. 

On my first gun the rear sight was small novak type and I cut about a cm off the back of a Clark rail with a front sight cut out in the rail.  and was just able to mount an ultra dot.  It worked but not elegant. 

if I did that over again I would cut a grove further forward maybe 1/4 inch forward of the back end to secure the scope better. 

Doing all that you loose one of the scope mount screws was not a problem blue locktite could not cure.

the best option if you have the money is to get David Sam's to install his system then you can put it on and take it off whenever you want. $385 is what he gets.

The RRA rib with sights is not legal for use in a CMP match.

Got them on all my was guns
Springfield puts them on our wadguns for the team

Terry these are the scope ribs that have adjustable rear sight and a front site, not the standard dot rib. Is that what you have?

I have std dot rib .

Being steel, these ribs are very heavy. If you put rings and a dot, it's way too heavy. 

The ones I have also lack adjustment arrows.

I installed mine last night on a gun that did not have a slide cut. 

As a result the elevation screw had to be loosened a lot to make the slide fit the frame. As the rail did shoot high on another gun I figured I could grind about 3/32 off the bottom of the screw while it was still on the rail so as not to strip. I used a medium stone a little frame black and it was good as new.  

A noted gunsmith told me not to do that, however I was lucky and able to zero the gun and have a few clicks to spare (I have 40 from the lowest elevation). I could trim the front sights by about 9/100s and make it even better but its good enough for Government work. As it is It hits the lower part of the xring from 6 oclock lowish. 

I then installed the red dot and Shot a 90 slow fire. I really like the added weight (not that much for me an its in the right places) and with a #10 spring it cycled just fine. 

So it's not a perfect product but the rear sight is nice and big and it works. If you got an old wad gun and need a plincker the Rock River Slide definitely solves that problem.

Rich, the dot you are using is standard right?

I used an ultra dot 1 inch and a Primary arms many just to check. 

Both worked well. I will be using the ultra because the mini was kinda close to the ejection port using the rock river rail.

I shot about 60 rounds with the miny and it held zero and no cases hit the lens but I'd rather use that on a Clark rail on a 1911 with that scope.
