Finally, I took my toy to a range.
I zeroed in at 50 yards. One scope couldn't be zeroed in due unavailability of required tools. But scope that was sold with a rifle worked just fine.
There were three major problems that popped up; weapon was not cleaned before shooting, use of surplus ammunition and unfavorable weather full of gusts.
This is what target looks like from a scope.
That view is from 120-150 yards away.
Now due to use of surplus ammo and not cleaning, it made my grouping 'urinating' poor. Also random gusts of wing really messed everything up. Also since I never had experience shooting scoped rifle, my marksmanship was lacking. But as time went on and I controlled breathing and trigger control, my grouping shrank. I can assume that with everything right, I will be able to accurately and consistently hit credit card size target at that range.
I found piece of metal laying around and placed a nice size dent on it.
Cleaning it during sunset was nice and 'romantic'
De-assembly is very similar to SKS and AK. Quick and easy to clean.
Shooting PSL is fun! It's not a sniper rifle - that's for sure. But as a squad support to lay fairly accurate fire, it does job very well.
