What Scope Rings for Pinty Falcon-X with Out of Spec Picatinny Rail

[mdhall54]

I was looking for my first PCP rifle and before deciding, I read and watched a lot of reviews of various offerings. I decided on the Pinty Falcon-X. I just received my new Pinty Falcon-X and overall, it looks like a nice rifle. This issue is I tried two different sets of Picatinny rings, and both fit loose on the rail. I contacted Pinty and they asked me to send photos, videos, measurements, etc. I did that and they wrote back that they were sending my information to their technical staff. I did research online and found that this has been an issue for well over a year. I wrote back to them, and their response was that I could receive a new rail around February 2027. Their website states that the rifle is shipped with a 21mm Picatinny, which is deceptive because it is out of spec. Now to my question, does anyone have a recommendation of what rings I can use until I receive the correct rail? I want to shoot the rifle but do not want to wait three or four months to do so. Thanks in advance for any help you can give.

@mdhall54 This may answer your question. I have found that Picatinny rings with circular "stops" fit the "scalloped-type" Pinty rails. Square stops don't.

Of course, you may have a different issue. If, so please post a photograph.

Thanks for the quick response. The issue is the rail is not 21mm wide, which is standard for a Picatinny rail. The Falcon-X rail measures 0.824" (20.8mm) which is just undersized enough that the ring bases come together before they can clamp tightly on the rail. I tried both a quick release ring and a standard ring. I tried to attach a video, but I could not get it attached. The video would have showed me wiggling the rings once they were attached as tightly as possible to the rail. I attached the rings to the rail under the forend and they tighten just fine. I am thinking I may try a Weaver style ring as they sometimes have a wider clamping range.

I have seen this on a number of different settings.
first the tolerance the gun maker set can lead to one being on the small side maybe within their specs but small but the biggest issue I have had had been with the cheap rings they ( at east what I have seen ) are always on the loosed I have seen people shim them so the y can use them.
I have a buddy that buys the cheapest ring he can and all of his have to have shims.
he bought a new EVOL MINI and called me complaining the says I cant beleave none the the rings I have fit and I just bought a new set and the are so loose I cant believe it.
so I grabbed a set of rings jumped in the truck and run over and goes what the rings fit perfectly
I have had good luck with Athlon and Eagle vision
not sure if that is your issue but I would think only being under .2mm wich is only 0.00787" wich is a larger tolerance the I would hold but still the isnt much.

I would be look at the rings if it was me?

Thanks for the response. Pinty sent an email to me admitting that the top rail was out of spec. I assumed this was the case when both sets of rings fit tight on the rail under the forend. I am going to try a higher quality set of Weaver style rings to see if this eliminates the issue. Pinty will not have "in spec" scope rails ready to ship for free until February of next year. Below is one entry I found online.

Airgun owners have complained about the scope mounting rail on the Pinty Falcon-X and other Pinty PCP bullpups. While the rifle is advertised with a 21mm Picatinny rail, shooters report that the rail slots and dimensions are cut to non-standard or Weaver-style specifications, which causes compatibility issues with standard MIL-STD-1913 Picatinny rings and one-piece mounts. [1, 2, 3, 4]
Reported Rail Issues on the Falcon-X

• Incompatibility with One-Piece Mounts. Owners report that standard offset cantilever mounts do not fit properly onto the Falcon-X rail. Because Picatinny cross-bolts are thicker and spaced differently than Weaver slots, one-piece mounts often fail to seat into multiple slots simultaneously. [1]
• Trial-and-Error with Scope Rings. Shooters note that mounting an optic on the Falcon-X often requires trying multiple sets of individual rings before finding a pair whose cross-bolts align with the rail's non-standard spacing. [1]
• Recurring Pinty Bullpup Rail Sizing. This complaint echoes a broader, documented issue across Pinty’s bullpup lineup (such as the original Falcon and Striker models). Owners on forums like Airgun Nation and Gateway to Airguns previously discovered that factory batches were machined closer to 19mm–21mm Weaver dimensions rather than true 21.2mm MIL-STD-1913 Picatinny specs, prompting Pinty to acknowledge factory machining errors and offer replacement rails or partial refunds on earlier runs. [1, 2, 3, 4]

I have a Falcon X and the rings in the picture work perfect. There are a ton in every size you could want online. Most one piece mounts will not work unfortunatly, but no issues other than that.



Yes if you want the 21mm milspec rail they will be availble next year. Just contact Pinty to get on the list.

These work great. What kind of scope are you mounting?

As usual the Google AI results are misleading in their information, but this was an issue with the original Thumper (original P-Pup), as they shipped with 19mm wide rails. I ended up doing a rail replacement for my brother when they came in, but it required me to go buy screws as the factory originals did not engage on the new rail. Being just under the 21mm, I would expect that one of the rings suggested by @Playingdead should work fine. Still unfortunate to see this issue potentially returning with the Gen 3 guns.

The West hunters are what I use on all my Pintys. They rock solid for sure, and inexpensive to boot.

The WestHunters look interesting. I especially like the adjustable height. I’ll look into them. Thanks!

This is what you need to do. While the Pinty rails are not PIC, nor Weaver they are the overall width of weavers. You would think, if Pinty was actually listening, after more than a year there would be no more "out of spec" rails, right?

I agree. Comments about this issue come up quickly back to mid 2025.

That's why I am so frustrated, finding out Pinty knew about this problem yet requested all kinds of information from me and not telling me upfront that it is a known Issue. This is the first purchase I have made from Pinty and after this experience, I would have to think about another.

I feel your pain!!! After 21 emails and over a month of time. No one ever admitted a problem with the rail. I just kept being told the replacement rifle would fix the issue. My issue was I could not mount the free Pinty scope to a Pinty Gun. Same as you it would not tighten up. The issue I had, there was not a way to use after market rings. The scope had a built in mount, and came with a riser that you had to use. I ended up taking a Vector clamping part and replacing the one piece that came with the Pinty Scope riser.

The very odd part for me I could get my new Vector Tauron to mount no problem, and my really old Bushnell Trophy with Pic mounts to also mount no issue. Even the Pinty Scope with out the Riser would mount no problem. But put that riser on and it would never tighten up.

Glad to know the Falcon has the same issue. I was about to order one of those.

I copied and pasted some verbiage I found on various sites into an email to let them know that I knew they had an issue. After doing that I received the email telling me that I could get a new rail at no charge…possibly by February. I am not going to wait that long to use the rifle and will get the scope mounted. My next PCP will be from another manufacturer.

If you don't like the falcon let me know I will buy it.

I have had noting but good luck with Pinty. I mean did you have your hopes set on a mount for the rail? Buying a set of rings is a deal breaker? I guess that is your hill to die on...

For a sub-500 dollar rifle I think people expectations are a little high. Not saying it should not have a Milspec rail, but damn. I also think before you pre-ordered a rifle you could have googled it, or joined HAM to see what it was about.

I am all for holding companies accountable, but I also think the consumer need to bear their responsibility as well.
