The LBE Unlimited low-profile gas block fits a .750-inch barrel journal and ships with a mid-length gas tube, so you have a matched block-and-tube set ready to install. The low profile lets the block sit cleanly under a free-float handguard. The block is steel with a nitride finish and the gas tube is 304 stainless steel.

Features:

• Low-profile .750-inch gas block
• Includes a mid-length 304 stainless steel gas tube
• Steel block with nitride finish
• Set screws and gas-tube roll pin included
• Made in the USA

Pair this with a .750-inch-journal barrel that uses a mid gas system. The gas-tube length must match your barrel's gas system length for proper function.
