Yes I did notice the liner was twisted a little bit I thought that it was loose so I twisted it until it was tight and went to tighten the 2 screws and they where tight ! I had a barrel band on it at first and I accidentally hit the barrel when bringing the gun inside Sunday before that I even had installed Picatinny spacers because I couldn’t adjust my scope it was touching the rail but before all of that it was tack driving every time I shot it! So I will but my Tactacam on and put my laser bora sight in and rotate the barrel and see what I get it’s going to be hard by my self so hopefully with the Tactacam I can look at my phone and make adjustments! Thanks guys I was about to buy another scope and rings!! Now I can buy pellets now !!
