Hello, this is a bit of an oddball question. I'm looking at replacement sight options for the Beretta ARX100 rifle, which has a high rail which AR backup sights don't suit well. I'm aware of Troy micro backups being a good replacement.
However, I'm checking out HK-416 type sights as another option and just leaving them attached. It seems there are few options to find them. RTG has knockoffs of unknown quality. HKnet has the real deal for big money. Midwest has a somewhat better deal on a german front sight, but still expensive. And Brownells has a better price on a rear sight but is out of stock.
I don't need "authenticity" for a correct build per se, so I really don't want to pay $400 for a set. Are there any other options out there for picking up a set? Is RTG's knockoff set GTG or just airsoft level? Is this just a dumb idea in general?
Thanks.
