F5-ACR Gen 3 Brace with Adjustable Cheek Piece (Select Platform)

The F5-ACR Gen 3 Brace with Adjustable Cheek Piece represents the next evolution of F5 Mfg’s flagship ACR-style platform—now purpose-built as a pistol stabilizing brace, not a rifle stock. Designed for shooters who demand uncompromising strength, precision, and adjustability, the Gen 3 introduces a fully adjustable cheek piece, a major performance upgrade over previous generations.

This enhancement allows users to fine-tune cheek height for improved sight alignment, increased stability, and consistent shooting ergonomics across optics, calibers, and firing positions—making it one of the most refined stabilizing brace systems available.


Fully Adjustable Cheek Piece – A Major Performance Upgrade

The Gen 3’s fully adjustable cheek piece is the standout improvement over earlier versions, offering:

  • Enhanced eye alignment with optics
  • Increased shooter comfort and repeatability
  • Improved control during recoil and rapid follow-up shots

This adjustment capability brings rifle-level ergonomics to a pistol stabilizing brace platform without compromising compactness or durability.


CNC Machined Billet Construction – Strength Without Excess Weight

The F5-ACR Gen 3 Brace is machined entirely from CNC-machined billet 6061 aluminum, not cast or molded components. The chassis body has been aggressively lightened with all unnecessary material removed, ensuring maximum structural strength without excess weight.

Designed to withstand extreme use, this brace is engineered to be one of the strongest components on your firearm, delivering rigidity, repeatable lockup, and long-term durability under demanding conditions.
