F5-ACR Butt-Stock – Adjustable Composite Stock for F5-ACR Folding Chassis
Lightweight, Adjustable Rifle Stock for SBR & Rifle Conversions
The F5-ACR Butt-Stock is a composite adjustable rifle stock designed to attach to the billet aluminum F5-ACR folding chassis (sold separately). Built for lightweight performance and user-specific fit, it offers length of pull adjustment without adding unnecessary bulk or weight. While the stock itself is non-folding, it seamlessly integrates with the folding functionality of the F5-ACR chassis, making it ideal for compact rifle and SBR builds.
Note: This product includes the butt-stock only. It requires the F5-ACR billet aluminum chassis for installation and folding functionality. Chassis not included.
