The 2A Armament titanium gas block is made from high-quality titanium. Titanium is a metal highly recognized for its lightweight yet sturdy structure.Because this gas block is made from titanium, its weight is reduced by as much as 40 percent compared to standard stainless steel gas blocks. When you’re always on the move, ounces start to feel like pounds; for competitive shooters, hunters and police officers, the lighter the weapon, the better. For people that are looking for a lightweight component, the AR 15 titanium gas block seems a necessity on your rifle.

An AR-15 gas block is designed to re-route the gases created when a shot is fired back to the gas key of the rifle. Upon reaching the gas key, they flow into the bolt carrier, where they aid in the ejection of the shell and the chambering of a new round. Each and every timethe trigger is pulled, the process begins again.

Because gas blocks play an important part in the operation of your AR-15, you will want to be certain that they are of the highest possible quality. The 2A Armament titanium gas block features a low-profile design in its construction. This low-profile design enables it to fit easily beneath the handguard of your AR-15. Also, the double set screw design ensures that the gas block remains secure on the barrel of your rifle. For an optimal installation, consider using blue locking compound. Furthermore, a dimpled barrel will help ensure that the AR 15 titanium gas block is properly seated for a superior shooting experience. If you are on the lookout for a gas block, do consider the 2A Armament titanium gas block for its titanium, light weight and sturdy design.

The 2A Armament Ultra-Lite Titanium Gas Block Comes in: .750 diameter and .625 diameter.

    I'm really liking all of the parts that I've purchased from 2A. This titanium gas block is beautifully machined, flawless finish and not obnoxious shiny,. A nice subdued bead blasted clean look. Top tier part. Highly recommend.
