about weapons:
the textures are nice, but still not like the acog, I think the old acog was better(more realist), the only problem is that it is high, and I think that could put the ACOG a little more to bring.
but, this new acog could be good in lgun.
while the rifle, I still think it is small.
you could try to draw the rifle like a G3C or fn-scar (compact weapons), i believe that would be good.
