DUO SPECIFICATIONS

PA 5X MP + HS ARO-CORE-RD-2: 492g with 1.54 and 2.87-inch optical centerlines

The DUO places the Primary Arms Microprism at the same 1.54” centerline height as the medium and straight spacers included with the optic.

Red dots vary, but the low-cut T1/T2 height ends up being about 2.7” from the top surface of the picatinny rail.

Alternatively, the Holosun ARO-CORE and 515GM come out at about 2.87”, with their EVO-SPR coming in at about 2.98”.

The Griffin GSP lands at about 3.02”.
