found a Donor (CYMA) for my KS-1 build. Now the hard part begins, so much to do.
if anyone is interested the plan is:
remove the QD points from the rear of the lower receiver.
chop out the right side bolt release and replace with a 3D modelled correct version.
either find or make the correct fire selectors
engrave both side of the lower
modify the charging handle to be ambi
print a outer barrel sleeve to replicate the dimples on the real thing
Cerakote everything
fit aftermarket parts (rail, grip etc) - still need to find knock off Mbus Pro sights and the stock pipe QD point
I've got a ACRO P2 but need to find the reptilla scope mount and find a suitable short dot that's close to the Vertex 1-10 (not spending £2000 on a scope!)
This may take a while.
