I have a KMR and it’s undoubtedly the best lbp I have owned and I have tried and owned all currently available.. The cheaper end are fun plinkers but accuracy isn’t up to much on any of them with the exception of the buckmark which is accurate but about as much a pistol as a vegetarian bacon..
My KMR will put a full mag through a five pence size group at 25 yards..this was from a ransom rest as I can’t shoot that well
