That is correct . I have a Belgian Browning in 22 short & the receiver is grooved . I also have a Japanese Browning in 22 LR (no groove) Scope mount is mounted to the barrel . Just received my crude Chinese copy (JW-20) The barrel is drilled & tapped for the mount & it looks like the holes are in the same place as my 22 LR Browning barrel . I will say if you stand back 10' and compare the JW-20 to my original Browning's the JW looks OK . But any closer & you see why it is a $125. rifle .
lol
This is the mount I have for my Browning
