Yes, it is long. It becomes tricky when shouldering the rifle while wearing body armor. I have two carriers, one is a Mayflower APC and the other an Agilite K19. It's terrible with the K19 because of the QD shoulder strap buckles.Hellion length of pull is 16.5" minimum. Way too long for most people.
Sight design is clever but has design flaws that cause vertical and horizontal errors in aiming.
FWIW, the average height for males in Croatia is 5' 11". That in my opinion, explains the LOP.
As for aiming issues, haven't experienced that under general shooting of 50 yards and further with an EOTech. The height over bore though does require a bit more Kentucky elevation when shooting man sized targets within 20 yards.
Personally, my biggest gripe after running drills with the rifle all day last Sunday is the mag well isn't flared enough. The bolt release became second nature after the 4th mag, but the lack of any flaring of the mag well opening was what slowed me down the most. I hope the after market addresses that.
Only other thing that irks me is the angle of the safety.
Oh, one last thing to mention is that it appears the barrel is of the tool-less, quick-change type. It's not detailed in the manual, but based on the exploded diagrams and the fact that there's an obvious button right behind the pistol grip, leads me to think that it comes out fairly easily. It seems one captive push pin needs to be removed in order to manipulate the button.
