Adam Roth of Aridus Industries has been updating Beretta 1301s. Nathan S. recently posted about the YT-1301 latch and shroud.
Well Adam has been working on a prototype optic mount for the 1301. It is partially inspired by the Midwest Industries Gen 2 AK handguard he has on his Saiga AK.
The mount replaces the factory picatinny rail and direct mounts any optic that is T1 compatible.
No word just yet on pricing or availability but I hear he may be making something similar for the Trijicon MRO.
