This guide details the installation and testing of the SB Tactical FS1913 Folding Brace, as demonstrated by Hop on TFB TV. It covers attaching the brace to a 1913 Picatinny rail and addresses potential issues like unintended collapse under recoil, referencing SB Tactical's redesign for improved reliability on platforms like the Ruger PC Charger. The guide emphasizes proper installation and function checks for safe operation.

Quick Summary

The SB Tactical FS1913 Folding Brace, tested on the Ruger PC Charger, experienced unintended collapses due to recoil. SB Tactical addressed this by redesigning the latch with a stiffer spring. The brace functions more reliably on platforms like the BRN-180 with linear recoil, while the updated hardware aims to improve performance on higher-recoil firearms.

Frequently Asked Questions

What issues were encountered with the SB Tactical FS1913 brace on the Ruger PC Charger?

During initial testing on the Ruger PC Charger, the SB Tactical FS1913 brace frequently collapsed under recoil. This was attributed to the 9mm blowback action and recoil forces not perfectly aligning with the brace's latch mechanism, causing it to slide open.

How did SB Tactical address the brace collapse issue?

SB Tactical provided replacement latch hardware with a stiffer spring to improve retention. This redesign aims to prevent unintended folding, particularly on firearms with higher recoil or misaligned recoil vectors like the Ruger PC Charger.

On which firearm platform did the FS1913 brace perform better?

The FS1913 brace performed more reliably on the BRN-180 platform. This is because the BRN-180's recoil is more linear, which aligns better with the brace's locking mechanism and prevents the unintended disengagement experienced on the Ruger PC Charger.

What are the available strut materials for the SB Tactical FS1913 brace?

The SB Tactical FS1913 Folding Brace is offered in two versions based on the strut material: one made of polymer and another constructed from aluminum, providing options for weight and durability preferences.
