Robar NP3 or NP3 Plus from y M4 H20 ?

[Xchief30]

I decided I would like to send my M4 to Robar to make into a H20 clone.

Which finish is the factory finished H20 done in ? Are all the internals done in NP3/Plus or only receiver and barrel ??

 

Thanks

Benelli had ROBAR use the Np3 finish. I believe the Np3+ was not developed at that time. One of my #11711 H20 units has all of the internals Np3 coated with the black front sight protector and black rear sight assembly.The other #11711 has the black trigger guard, hammer,front sight protector and rear sight assembly with everything else Np3 coated.
