Yes—the specifically listed Umarex HDP50/TP50 GEN.1 GEN.2 Picatinny Rail fits both Gen1 and Gen2. Z-RAM’s product-specific confirmation covers that exact rail, supplied with two mounting screws and two nuts. A red-dot sight is a separate item, with its own rail-mount requirement and package contents.
The generation answer belongs to this exact rail
The confirmed offer is named “Picatinny Rail Umarex HDP50 TP50 GEN.1 GEN.2 Custom Fit RED DOT SIGHT.” It is listed as 3D-printed plastic. The same rail is offered for both generations; you do not need to choose a separate Gen1 or Gen2 version when ordering.
There is also a separately listed HDP50/TP50 rail with a shorter “Perfect fit” title. Its description does not explicitly state a generation. The similar name does not confirm which generations that separate rail fits; its missing generation wording does not establish that it is incompatible either. The card below points to the offer with the explicit two-generation confirmation.
Separate the two sides of the fit question
The rail has to fit the HDP50/TP50, while the sight has to fit the rail. These are different relationships. The positive Gen1/Gen2 answer settles the first for the named rail. For a particular optic, its mounting interface remains the relevant check; a list of marker names does not replace that information.
The separately offered New-Version Red Dot Sight has a stated 20 mm Picatinny mount. Z-RAM’s guidance for that optic makes the presence of a suitable Picatinny rail decisive, not the marker name alone. Read it as a separate optic to compare by its mount, not as an item included with the HDP rail or a claim that it attaches directly to every bare marker.
Keep the supplied hardware with the right product
The rail package consists of the rail, two screws and two nuts. The New-Version optic has its own set: the sight, a CR2032 battery, lens cover, Allen wrench, cleaning cloth and operation manual. Those are two distinct offers. The optic’s tool and accessories should not be added to the rail’s stated contents just because both appear in the same guide.
If you already have a suitable sight, the confirmed rail’s generation coverage and included mounting hardware may be the only purchasing information you need here. If you are also choosing an optic, compare its mount and supplied accessories separately. You do not need to select a separate generation version of this rail or buy its listed mounting screws separately.
