Ruger SFAR Review, Breakdown, Test Shooting & Buffer Weight Swap | AT3 Tactical

Published on July 21, 2023
Duration: 8:19

This guide details modifying the Ruger SFAR by swapping buffer weights and testing different .308 ammunition types. It highlights the importance of buffer selection for recoil management and reliable cycling, especially when using suppressors. The video emphasizes that while minor buffer changes may not drastically reduce felt recoil on this platform, specific buffers can aid suppressed fire. Compatibility notes for AR-15 sized lowers are also provided.

Quick Summary

The Ruger SFAR, an AR-15 sized .308 rifle, features proprietary components like a 3-position gas regulator and ported BCG. Testing showed that while heavier buffers like the H3 improve suppressed performance, significant recoil reduction from buffer swaps alone is limited. Most tested .308 ammunition cycled reliably, but AR-10 bolt catches are recommended for proper fit.

Frequently Asked Questions

What are the key proprietary components of the Ruger SFAR?

The Ruger SFAR features a proprietary M-LOK handguard, a 3-position gas regulator, and a heavily ported bolt carrier group designed for off-gas management, differentiating it from standard AR-15 and AR-10 designs.

How does buffer weight affect the Ruger SFAR's recoil?

While a lighter 3 oz AR-15 buffer is standard, swapping to heavier buffers like an H3 can improve performance, particularly when using a suppressor. However, significant recoil reduction from minor buffer changes alone is limited on this .308 platform.

What ammunition types were tested with the Ruger SFAR?

The review tested various .308/7.62 ammunition, including Armscor Rifle Line 150gr, Winchester 308 Win 150gr, Range Dynamics 180gr FMJ, and PMC Bronze 308 Winchester 147gr, with most showing reliable cycling.

What are important compatibility considerations for the Ruger SFAR?

The SFAR uses an AR-15 sized lower receiver, requiring attention to parts like the bolt catch (an AR-10 size is recommended) and potential need for spacers with certain recoil spring systems like the Armaspec Stealth.
