G&G gr16-a3?

Question

Ok so im going to buy a G&G GR16-A3 in a couple of days and the gun seems flawless, but i have 1? does this gun have metal hopup?

Please help

Thx

Answer 1

The hop-up mechanism is metal if I recall correctly, except for the hop-up sleeve itself. This part is always made of rubber. The mechanism changes the shape of this rubber sleeve to impart different degrees of spin on the BB's, thus adjusting their trajectory.
