For many years Rem has been re-branded Crosman/Benjamin.
With the 2020 break up of Rem, Crosman MIGHT have lost the Rem name. I'm not sure.
Otherwise, assume it's the same category as all their other NP rifles, but with a nicer stock. By that, I mean lipstick on a pig.
14-16fpe would be a safe bet.
Maybe you can hash something out of this thread https://www.gatewaytoairguns.org/GTA/index.php/topic,24705.0.html
The useful model #s there might be
8M = Titans / Venom / Vantage NP : (Venoms)CD8M22NP, CD1K77NP, CVW8M22NP, CVW1K77NP.
(Vantage NP) R1K77XNP
(2010 Titan) C8M22NP
(2011-2012 Titans) BW8M22NP, BW1K77NP
9M = Trails (not the Trail XL's) : BT9M22SNP,BT9M22WNP,BT9M22CNP,BT9M22LNP
BT1K77SNP
Or if you're UK, you'll need the detuned ram.
Crosman will sell you any part you want, IF you know the part #.
For example, my Titan NP had a Remington (Crosman) compression tube swapped on, for the rail vs dovetail. Cost $20-ish?
EDIT
I WENT TO GET A LINK FOR THE PARTS DIAGRAMS, since I KNEW it was there, but couldn't find.
Oh... yeah... fuck Crosman. Even their help section is unhelpful.

JMHO on Crosman, they are the sort of people who act REAL NICE, while being A-holes. Saccharin sweet.
In the USA, we call that "Professionalism" and it bears no semblance to competence, or being a professional anything.
Maybe we should be happy they'll sell us a part to fix their factory defects?
I dunno. JMHO, a decent company would have QC under control, instead selling junk (that's what the warranty is for ? ? ? )
Here is a good link for all models

Searching some of those part #s leads to this

The seal is same as every other nitro piston in the lineup

In exchange for the effort I put in here, please find the actual model number, so I can call and get a price on that sexy stock.
