SOLGW Gas Block Overview

Thursday, July 23rd, 2020

This is a critical, yet often overlooked, part of building a fighting a gun.

If you’re hemorrhaging gas between the block and journal you have a less efficient system…which means you’ll need more gas…or the rifle will be more sensitive to conditions that are less than ideal.

These are some of the details that make SOLGW a more robust system. Our tolerance specifications are written specifically for this.

“But they don’t actually make anything…”

Yes we do. We make very reliable rifles…
