Expo Arms Low Profile AR-15 Gas Block - Nitride - Set Screw - .750"

The Expo Arms Low Profile AR-15 Gas Block is a precision-machined steel gas block designed for barrels with a .750" gas seat diameter. Built with a secure dual set screw mounting design, this low profile gas block fits under almost any free floated handguard on the market and is proudly made in the U.S.A.

Features:

• Low profile for use under free float handguards
• 4140 chrome moly steel construction
• Salt bath Nitride finish for corrosion resistance
• Dual set screw mounting
• .750" gas seat diameter
• Precision machined for a consistent barrel fit
• Made in the U.S.A.

This version uses a salt bath Nitride finish instead of Expo's manganese phosphate option, for shooters who prefer a nitride-finished gas system to match a nitride-finished barrel or bolt carrier group. Expo Arms backs this gas block with its Limited Lifetime Warranty against manufacturer defects in material or workmanship, as well as normal wear and tear, and this version does not include a gas tube roll pin. The dual set screw design keeps the block secure on the barrel while staying compact enough to disappear under a free floated handguard.

Expo Arms manufactures mil-spec AR-15 components at accessible prices, backing its parts, including this gas block, with a limited lifetime warranty against defects in materials and workmanship.
