Overview

Aridus Industries offers a practical way to adapt a Beretta 1301 for use with the Magpul SGA stock, giving owners access to a stock option originally associated with the Mossberg 590 platform. The adapter is machined from 6061 aluminum with a hardcoat-anodized finish, and it uses a custom fastener machined from 4140 steel to secure the stock attachment. It is aimed at shooters who want to tailor the 1301’s setup for a more familiar SGA configuration without changing the shotgun’s core platform. For hunters and field shooters who value a straightforward upgrade path, it provides a focused compatibility solution rather than a broad-purpose accessory.

Pros

  • Allows Beretta 1301 owners to attach the Magpul SGA stock
  • Machined from 6061 aluminum for a solid adapter body
  • Hardcoat-anodized finish meets military specifications
  • Includes a custom fastener machined from 4140 steel
  • Designed specifically for the Beretta 1301 and Mossberg 590 SGA stock interface

Considerations & Trade-offs

  • Requires a Magpul SGA stock to complete the setup; the adapter itself does not provide a stock on its own.
  • Designed specifically to bridge the Beretta 1301 with the Mossberg 590 SGA stock pattern, so it is not a universal stock solution.
  • Installation and fitment details are not provided here, so compatibility should be verified against the intended 1301 configuration before purchase.
  • The adapter adds an additional interface between the shotgun and stock, which may be a worthwhile trade-off for ergonomics but also adds another component to the system.
