Need advice

oilcan · Jul 9, 2017

LAST EDITED ON Jul-09-17 AT 05:36PM (MST)[p]Set up my CVA Accurate V2 with Williams shorty ramp and Lyman 17A globe in front and Williams ghost ring in the rear.
Went to range to shoot it today and I ran out of elevation adjustment. It's dead on at 50 yards but the sight is cantalevered over the ramp. Any one have any ideas how this one can be modified or suggest a different rear that would work. I would like to get this set up complete so I can just consentrate on shooting.
Thanks

I'd Find a Quality Metal Shim & it looks like you need a Thick one!

That or try finding a shorter Front Sight!

I would bring it fully back onto the ramp, and try sighting it in with a 6 o'clock hold. See if that will work for you before shimming and getting creative. Going up 10 gr will also result in about a 1 inch change at 100 yards.

This is the right answer.

Which 17a did you mount? 17AML or the AHB? which one?

oilcan · Jul 9, 2017

idahoron it's the 17ALM

Don't know anything about shimming where can I get some info.

I had the same exact sight set up as you and had the same problem. Williams makes an adjustable rear Peepsight called the fool proof with target knobs .( fptk). I found one for my Remington muzzleloader and it works great. I can shoot from 100 yards to beyond 300 by just turning the elevation knob to the proper range. It also has a knob to adjust windage which is very handy for sighting in. The only drawback was I had to drill and tap for the mounts on my receiver. Maybe you can find one that will fit on your existing holes.

I added the Lyman 17 AHB it is a little lower sight than the AML. I also use Lee Shavers globe inserts for BPCR. They are super fine and designed for 1000 yards.
Either way you would probably need to shim that rear sight.
I shimmed my Knight MK85. I put a 17AHB on it and a Williams PF peep. I added a Gib Lock screw so I could loosen the peep sight in the field and adjust the sight to the shot. So if the shot is 125 I set it for 125. If the shot is 150 I set it for 150.If it is 72 yards I ca set it for that. I have it sighted in out to 250 yards but I don't take a first shot at game past 150.

Since the sights are raised I needed to raise the cheek pad. I got this one on amazon cheap.

This is a picture of my son shooting out to 250 yards.

This is a target that he was dialing in his sight for 250.

In this picture you can see the dark spot on the target is the same as shots #7 and 8 on the paper target. There is actually two hits on the steel there.

I have set up two rifles like this. The easy thing for me was the williams FP sight is easy to work with. My receiver on my two rifles are flat so shimming is no big deal. For yours it will be harder but doable.
If it were me I would get a williams FP sight that is flat like mine. Then I would buy a weaver scope base. I would have the scope base milled flat then drill and tap it. Then mount the FP sight to the weaver base. You can either mill it flat or use a sander to flatten it out and reduce some height. It depends on what you are comfortable doing.

oilcan · Jul 10, 2017

idahoron,
So in your suggestion since they don't make a williams FP sight for my gun I could just buy they one for the MK85 right ? And for the weaver bases which ones do you suggest ? I looked online and there are a ton of them. There are no stores around me to check these out and it's a pain looking online to see how these parts will fit togeather especially not knowing how they will mount to the gun. I don't want to have to order them one piece at a time.

buckhorn,
I do not want to drill and tap the receiver and after calling around looks like I will not be able to get a gunsmith to work on it in time. I don't mind modifying the sights if I screw them up I can always buy another one. I feel like I'm falling behind getting this thing set up I thought I'd be just practicing at this point.

oilcan · Jul 10, 2017

I'm also shooting with the Lee shaver inserts. I took some bright fluorescent orange finger nail polish and painted the crosshairs I think it works pretty good but not sure how long it will last on there.

buckhorn · Jul 10, 2017

You are running out of time fast. I'm afraid at some point you are going to need to do some drilling and tapping whether it is on your receiver or on an adapter plate. The front sight set up I have is the 12 gauge shotgun ramp which is 1/8 inch tall and the lime in globe is the .404 which is the shortest one they make. For the rear you need at least another 1/4 inch of height. With the Williams FP I can shoot from 100 to 300 yards with only about a quarter of an inch of adjustment on the knobs. Check out this pic and you can see that I have a lot of more adjustment for longer range but the way it is now it's dead on at 275 yards I really don't need to go much higher than that because I can't see the target very well anyway at that range

I don't know if they have a FP sight for it or not but you will need a shim either way. If they make a rounded mount for the sight you will need a rounded spacer. That will be hard to do.
That is where the weaver base comes in. It will be rounded so it matches the barrel. The top part of the weaver base can be altered so the flat top style FP can be mounted to the weaver base.

oilcan · Jul 10, 2017

Ok that sounds good

kalielkslayer · Jul 10, 2017

Oil,

Buckhorn described his set up. Can you get a lower front sight?

That would be the same as raising the rear.

Just my .02 cents.

txhunter58 · Jul 11, 2017

I agree, the fastest fix would be to find a shorter front sight. I would definitely try that first.

That said, on one of mine I used a piece of a refrigerator magnet cut to match the bottom of the rear site to shim it higher. Remember that when you adjust the rear peep, you are going at an angle, so you have to raise it a lot to raise it a little. With a shim, you raise it 100% of the shim distance.

venor, ergo sum (I hunt, therefore I am)

oilcan · Jul 11, 2017

Tx,
I may try that before I start buying new parts.

Kali,
I talked to the williams tech rep yesterday he said I could switch to the .404 front sight but that alone would not fix the problem. But if I do that and shim it like Tx suggested that may work.

Now i will have to find longer screws for the shimming.
You would think they would come up with a easier way to mount these sights it's not like they just started making CVA's.

buckhorn · Jul 11, 2017

Another option may be to cut a dovetail notch in your barrel for the globe and do away with the ramp completely.

Idahoron · Jul 11, 2017

That would do it.

kalielkslayer · Jul 11, 2017

CVA doesn't want you to buy aftermarket stuff and put it on their guns.

They should design/market a peep specifically for their gun, charge 150% of what Williams charges and make $$$ and build a reputation.

But I'm just a sums prison guard, what do I know?

But you need to get that thing dialed, time is ticking.

No pressure.?

A good machine shop could cut the dovetail in your barrel like was suggested. Or a great gunsmith. That would be worth $100.00 if I was in your position.

buckhorn · Jul 12, 2017

When I was considering having the dovetail cut for my front sight a gunsmith in Reno could do it on a mill for 50 bucks another one wanted to $75.

Fubarracin · Jul 13, 2017

I really like the magnet idea, I think that's going to be my solution!

oilcan · Jul 21, 2017

Used the magnet for the shim and it worked great it contours to the barrel nicely.
I am shooting under 2" groups at 100 yards which I am thrilled and very surprised.
I did not think I would be able to shoot that good with the open ( peep ) sights.

kalielkslayer · Jul 22, 2017

Good luck with your new toy and tag.

buckhorn · Jul 22, 2017

That's good news oillcan. Now you should go out to 250 or 300 and see if you can adjust your site for that range. It's going to be a whole lot harder to see a deer size target however. That buck of a lifetime may not be only 100 yards away. Please let us know how you're doing at the extended ranges. Thanks
