AI Overview
Ruger 77/22 and 10/22 barrels are not directly interchangeable, as
the 77/22 tenon (the portion that inserts into the receiver) features a longer shank, different v-block placement, and specific extractor cuts. While both use a similar slip-fit design, 77/22 barrels require significant modification to fit a 10/22, and 77/22s made after 2009 use threaded barrels, not slip-fits.

Ruger 77/22 vs 10/22 Tenon Differences
- Shank Length: The 77/22 barrel tenon is generally longer than the 10/22 tenon.
- V-Block Position: The dovetail notch for the v-block is positioned further back, closer to the chamber, on a 77/22 barrel compared to a 10/22.
- Extractor Cuts: 77/22 and 10/22 barrels often have different extractor cuts. While some aftermarket barrels are designed to fit both, they may require specific modifications, notes this article on Rifle Barrels.
- Post-2009 Change: Pre-2009 77/22s use a slip-fit, v-block system similar to the 10/22 (but with different dimensions), whereas newer 77/22 models utilize threaded barrel attachments.
- 77/22 Barrel on 10/22: It is possible, but usually requires shortening the tenon, recutting the dovetail for the v-block, and lathe work to ensure proper headspace and extractor function.
- 10/22 Barrel on 77/22: This is more difficult due to the shorter tenon length and v-block position, making it less common.
- Conversion: A 17HM2 barrel can be swapped onto a .22LR 77/22, or a .17HMR onto a .22WMR, but they are not directly interchangeable between calibers that require different receiver sizes.

The RPR Rimfire employs a barrel extension much like the AR15. The extension screws on.
I'm told it isn't a big deal to make a barrel change on the RPR Rimfire and barrels are available from Jarvis at a fairly decent price if you want aftermarket.
So, to answer your question, the 10/22 and RPR Rimfire barrels are not interchangeable.
