Why are Cyma (and I think Well) sniper rifles so much heavier than JG?

Clearly there is more metal in them, but where is it?

 

Do they use any steel parts?

[AK47frizzle]

Pot metal is significantly heavier than aluminium. Unlikely steel because... well, it's cyma.

[emilianoksa]

True, but the JG will be pot metal too.

Most of the weight of my MB-03 is in the outer barrel.  Even fractions of a mm in thickness will add up pretty quickly.

My well l96 did have a massive chunk of metal glued into the stock!

The MB-03 could do with some more weight at the back, I've been ponding filling the stock with silicone gloop.
