Frequently Asked Questions

What makes the Triarc 12.5-inch upper receiver shoot so softly?

The soft shooting characteristic is primarily attributed to the Triarc Track 2.0 12.5-inch barrel with a mid-length gas system and a larger .076 gas port. This setup, combined with a standard carbine spring and buffer, significantly reduces felt recoil, making it very pleasant to shoot.

What are the key components of this custom Triarc AR upper build?

The build features a 12.5-inch Triarc Track 2.0 barrel, an 11.5-inch Midwest Industries Combat Rail, a Rubber City Armory BCG, and an FCD 6315KM muzzle device. The upper receiver itself is a Cerro Forge keyhole forging.

How does the gas port size affect the shooting experience on a 12.5-inch barrel?

A larger gas port, like the .076 used on this 12.5-inch mid-length system, results in a softer recoil impulse. This is because the gas system operates with less pressure and dwell time compared to longer barrels, leading to a smoother cycling action.

Is this build suitable for suppressed shooting?

Yes, the build is considered very good for suppressed shooting. With a suppressor attached and using M193 ammunition, the ejection pattern is expected to be around 3:00 o'clock, indicating optimal function and a manageable recoil impulse.
