the 50 meter V-rear sight can be used, have not try the peep sights

yes, it looks very martial but you can screw off the Cetme/G3 flash hider and use the thread for a silencer still having a short rifle.
coming back from the range for a first test sadly it don't like the lapua naturalis making a 20 - 30 cm circle at 50 meter. the barrel is like new so this is not the problem.
for an interim solution I sighted it for geco softpoints.
