I have 22 Grendel improved upper I was thinking about selling 40 degree shoulder . 8 twist ss barrel 24" . I have built 4 of these and all shoot lights out . They are pig killers ! 80grain Bergers are very accurate and bang flop on most pigs . I have to many uppers . I have a 7 twist fluted barrel upper also . both are side chargers . one is Gibbs arms upper reciever . I will sell dies or you can get a 6mm Turbo 40 FL bushing die from Robert Whittley and I will convert it for you .
