hi
after your advice
I just Dismantle again
I had everything well greased, but I degreased and regreased with new grease
(white lithium grease) and I put for real
I check the alignment of gas, everything is ok
the valve spindle is ok
I returned shoot and there have been improvements, but it's not there yet
By the time a mag 5 will go great and even after the mag is not in semi auto
on the op rod and bolt, I made two observations
mid race the bolt is hard and share a little on the left side when I look through the hole where the mag goes
and op rod, I feel that when it is fully in back (when I pull for arming), affecting in its portion to the butt
on the second picture you can see the op rod that touches the barrel

but the thing is, especially by the time everything works fine
on 50 shots, say 20, which go well
this is better than before
but 'm really irritated because it takes great
what happiness when 5 shot going well in rapid fire, the muzzle brake is really very very effective both in shooting sitting and standing
I recommend it to all
thank you to all
