Definite improvement with that maroon colored Russian grip. Also, it took its first visit to the range Sunday and did perfect, as expected. I was at 25 yards (because that's the only firing line I could access at the time) and my groups started at least a foot from center around my 8 o'clock. My trust sight pushing tool got that handled, with help from a pair of pliers. I didn't do any rapid fire as it's not possible at that range. But I never had a single solitary issue. Very typical of the Kalashnikov platform.
Also, I should point out that my groups weren't any larger at 25 yards with my Krink than they normally are with my full-sized AKS-74 in 5.45mm. Now, granted, it's 25 yards and I'm anxious to run it at 50 and 100 but it's still surprising to see that within 100 yards a full-sized bore will barely out perform it. Intuitively, you just wouldn't expect a barrel that short to be so accurate. Definitely my new favorite gun!
