Pre-Installed Gas Block and Tube from LBE Unlimited

Remove the hassle of trying to pin the gas block and gas tube for your AR-15 with this pre-assembled package from LBE Unlimited. This kit comes with the gas tube already pinned in place, so all you have to do is slide the steel gas block onto your barrel’s shoulder. After adding some threadlocker to the set screws and tightening to spec (around 25 in/lbs), you’ll be ready for the range in no time.

Be sure to check your barrel’s specifications to select the correct gas tube length. This package is available with Pistol, Carbine, Midlength, and Rifle length gas tubes. If you’re not sure what you need, check out our article about gas system length in the AR-15.
