Anybody out there who can confirm the same, that there barrel thread grub screw is infact fitted
The threaded hole you have shown is where your stock bolt screws into on the .17HMR ....my two CZ's are the same just remember when you screw the stock back on the the front bolt is slighty longer by 3 threads .....i always make sure that both stock bolts are the same tightness too ......my 22" barrel silhouette can do 15mm group at 100 yrds no problem ....my 22" barrel style struggles to do a 25mm group at 100 yrds.....and both are cleaned every 300 rounds ......hope this helps mate ......AT
