tell what ?
That’s it’s a KAC PDW clone ?
because it looks like a KAC PDW , with no trade marks . The original by VFC had fairly deep engravings if I recall .
d-boys clone over WE AEG clone - smooth grip on the D-boys , dimpled on the WE .
the rear takedown pin position is slightly different to the later versions so I’m going out on a limb and saying it’s an earlier version ( maybe even not D-Boys but someone like Galaxy ? )
also Fire selector looks off .
memory is a bit hazy though , it’s been over 10yrs since I had hands on one .
Ok , now I’m looking properly Look really closely at the magwell , there is some light trademarks / engraving there ,
here’s a review from 2010
