Durable ah... Depends wad kinda conditions u subject it to. Like
someone mentioned on this forum, some SAR-21 scope tend to fog up,
and not clear up.
Reliability... this one was told to me from my friend. His Sar-21
jammed up so badly once that he had to slam the butt down on the
floor while holding the cocking lever just to clear it. Brute force
approach.
His Sar-21 was still able to shoot after that, so i'd say its as
durable as the M-16?
