If you want to build a tough, lightweight rifle that resists corrosion in even the most tenacious of environments, consider using titanium components. Titanium is considered superior to steel mainly because of its high-strength-to-low-weight ratio, low density, high corrosion resistance and wide temperature range resilience.

Reasons enough why Lockheed built its famed long-range, Mach 3-plus spy plane from this miracle metal—in fact, as much as 85 percent of the SR-71 Blackbird’s structure was made of titanium.

These remarkable attributes lend themselves well not only to aircraft airframes and spacecraft rockets, but also to high-temperature firearm applications such as sound suppressors, muzzle devices and gas blocks as well. While titanium parts are advantageous to use for these characteristics, they can also add a bit of flair to a build.

The current lightweight carbine trend means a focus on weight loss, and finding ways to shave those last extra ounces off a rifle can get tough. Titanium parts easily help eliminate a few more ounces, which is a nice perk, especially if the replacement parts are stronger to boot.
