My Jackplate files to stay secure on my bow's rail (R20) after approx 200 shots.
Looking today at a few dealers sites (Ravin) I notice the pics they have of Jackplate for Ravin indeed has 3 hold down screws.

My Jackplate only has 2 holes with screws to secure to bow's rail.

Will post a pic.

I have sent pic of my Jackplate to Ravin for action/explanation.
The support person on the phone didn't realize there were any Jackplate with only 2 hold down holes /screws for securing to rail.
Will provide additional feedback here as I receive.

Some actual feedback from Ravin Jackplate guru at Ravin.
They assure me the pics posted on the various dealer's sites are indeed in error. (Showing 3 hold down screws).

They assure me there are only Jackplate models made by ravin for Ravin bows with only 2 screw hold downs.
They want to to send mine in and evaluate.

I do not own a Ravin crossbow, but viewing the picture on the link you submitted, it looks like there are three hold down screws for the jack plate in front of the jack plate wheel. Possibly this is an upgrade for the 2018 models as at the top of that page it says something to the effect "New For 2018".
Thanks for sharing.
All the best.

Anyway the way it is set up (2 screws holding) won't last IMO.
Too much weight vs recoil.
There is not much flange extending underneath rail to grip to rial when tightening screws.

Ever see some of those scope mounts for the spring piston air guns? They have 3 or 4 hold downs. For good reason.
I will not use mine when it comes back. Even if they send me a new one.
May offer up here at reasonable price.
The entire strip where the bolts exist should have been a little longer, and a third securing bolt added.

Per conversation I had with Ravin (Brock) I think his name was, there is and has been only one versions of jack plate. One that has 2 hold down screws/ nuts.

I sent my Jackplate to Ravin to be looked at.
It would not sit still in the back with both fasteners to rule. When I would lift up on scope I could see Jackplate raise on the bow's rail.

We'll see what they say.
And I probably even had my scews over torqued a bit (purposely) and still couldn't get my plate not to move in the rear when installed on rail.

I will say the Jackplate fitment could be better, but once torqued to the required in/lbs everything holds tight and true with no movement. PS only two bolts * make sure you have a torque wrench that reads inch pounds not foot pounds, some don't know the difference, foot pounds would over tighten the bolts.

I purchased a new Tenpoint Stealth NXT bow back in Sept. and was not very impressed with the scope that it came with. I really liked the idea of the Ravin jackplate design along with the HHA Optimizer and using a scope with a single crosshair. I was a little concerned about the HHA side knob possibly getting in the way with accudraw pro so I bought the Ravin jackplate and a Leupold VXR 1x4 firedot scope. When I began mounting the jackplate it slid on the scope rail and lined up with the slots perfect, I then installed the rings and scope leaving all screws snug. After getting everything right where I wanted it, I started to lock the jackplate screws down and found the base of the plate was so solid or strong that the screws would not squeeze the mount down to the base rail mount. I decided that I could tighten the jackplate up if I used some shim material. I wound up using .008" shim material to tighten it up and get it shooting. I soon found the bow did not group as well as it did with the stock scope and rings, so I pulled the jackplate off and measured the scope rail width and it was pretty damn close to even after measuring the jackplate I found it was wider at one end. Both front and back were a loose fit but one end was larger. After thinking about it, I carefully put the base of the jackplate in my vise and started squeezing the rail lips together a couple of .001's at a time until I got it real snug, so snug I had to tap it on the scope rail with a small plastic hammer. Then I re-installed the everything again on the jackplate and now my bow shoots dead nuts! and I love my set-up.

I just would like to share my experience with the Ravin Jack Plate, so others can benefit before purchasing it.
I have a Tenpoint Nitro XRT which has an original Weaver Rail from Tenpoint (no modifications here).

I decided to buy the Ravin Jack Plate due to its capabilities of extending your shots up to 200 yards (as claimed somewhere in their website/sellers online, etc..). I am not sure though if it says 200 MoA or 250 MoA of elevation adjustment, it might have some contradictions in different sites I had a look before.

Well, I looked a lot through YouTube videos, Forums, websites, but there is not a lot of information on these Jack Plates, to be honest almost none (does it suit a Tenpoint Nitro XRT or other brands? how do you mount in different rails? dimensions? weight, etc...), so I decided to buy anyway and figure out a way how to fit it in case it did not fit my Crossbow rail, the design looks pretty slick, the adjustment on a horizontal wheel looks better and less clunky in my opinion, and the extended range when removing the lever from the wheel made me choose this one instead of the HHA Optimiser.
Once again, in my opinion it does not make much sense to use an HHA optimiser to shoot out to 100 yards in my case, considering my scope has cross hairs up to 80 yards, for some people it might make more sense if they are using a red dot for example. For target shooting, I wanted the capability to shoot up to 200 yards (we are not allowed to hunt where I live anyway).

I put together a mosaic of pictures and notes here, for easy of explanation, but summarising you cannot fit the Jackplate straight to the Nitro XRT rail, you have to use an adapter, I believe someone here used a vice to squeeze his jack plate to fit on a Tenpoint Stealth NXT (I think he might not have realised Tenpoint uses Weaver 20mm and the Ravin Jack Plate seems to be for Picatinny rail system 21mm, please see picture attached).

I still have to get some low height scope mount to replace my current ones, because my scope is obscenely high on my crossbow. I will possibly put another update here once I try and shoot with it for a few dozen shots.

By the way, pay attention that my Ravin Jack Plate does not look with the one on Ravin Website, neither Wyvern Website which I bought it from (is it an old version? new version? is it fake, is it chinese? no idea....)

Please guys leave some comments about your experiences with these pates on Tenpoint crossbows, I would like to hear if more people got similar Jack Plates like mine.

I had one on my Scorpyd Deathstalker and the either my rail was narrow or the Jack Plate was a bit wide.

I had to tighten it to about 60 inch pounds with my Wheeler Fat Wrench to get it to hold.

I had thought about removing the cross screws and giving it a squeeze in my wood vice but chickened out.
