Aridus Industries has already developed an adapter that allows Beretta 1301 owners to mount Magpul’s Mossberg SGA stock on their 1301. Now they are working with prototype adapters that will bring the Magpul Zhukov Handguards to the 1301. The Zhukov handguard could be a great match for the 1301 due to their length and variety of MLOK mounting options.
The image below also shows a prototype version of their CROM mount for the Trijicon RMR. The CROM mount is already available for Aimpoint Micros. It is a direct mount that provides both a mounting surface for the optic and a ghost ring back up sight.
