Browning Semi Auto 22 Cartridge Stop

So I lost this little part while cleaning it, and it's a big problem getting such parts from the US.
So here it is, I printed mine in PLA, didn't test it a lot (20 rounds), but it works.
I'm not sure if PLA will hold it on continuous fire if the rifle gets too hot, so I'd suggest printing it in ABS or PETG.

Oh, and print it with the flat side down.
