點解M16越來越重

?? you tell me how heavy it become now?

the base model is 12 lbs w/o magazine.------ i own one, i did not weight it yet, but the manual say so.

however, you can add the leaser, flash light, battery pack, genade launcher, scope, night vision.....etc. then of course it increased the weight la.

actually. there are short shock and down size model ---- which can reduce the weight to 9 lbs, and still can add up some accessories if needed.

大概是因為在上面裝了越來越多的裝備吧
如各種瞄準具、激光指示器、提把等
另外槍的內部也自然會被改良
可能因此而越來越重吧
