Frequently Asked Questions

What is the PSA Saber 18 and what makes it unique?

The PSA Saber 18 is a firearm platform from Palmetto State Armory, notable for its FN-manufactured barrel, potentially using the same CMV steel as M249 machine guns. It serves as an excellent base for builds, including SPR configurations and GWOT-era inspired clones.

How does the Atrius Dev FRT trigger function, and what are its benefits?

The Atrius Dev FRT (Forced Reset Trigger) allows for rapid firing by resetting the trigger with each cycle, but only fires one round per pull. It offers a significant increase in rate of fire over standard semi-auto triggers without being a full-auto sear, making it a popular upgrade for AR-15 platforms.

What kind of accuracy can be expected from the PSA Saber 18 SPR build?

With a 10.5-inch FN barrel and Aimpoint optic, the PSA Saber 18 SPR build achieved sub 1.5-inch groups at 50 yards using Super Vel 77-grain OTM ammunition, demonstrating good accuracy for its configuration.

What modifications are recommended for the Atrius Dev FRT trigger installation?

When installing the Atrius Dev FRT trigger, it's recommended to use a compatible single-stage trigger like the Schmid and an H2 buffer to prevent bolt bounce and ensure reliable function, especially at higher rates of fire.

How does suppressing the PSA Saber 18 affect its performance?

Suppressing the PSA Saber 18 with a device like the Griffin Armament M4 SDK significantly increases the cyclic rate and gas blowback, making the firearm feel much faster but also leading to a gassier shooting experience. It also reduces the overall sound signature.
