The GG&G M1A Scout Scope Mount is perfect for setting up your rifle with a red dot scope or long eye relief magnified scope. It easily installs in the cut out of the upper factory handguard. GG&G cut a large channel in the rail so that the iron sights could be used with the scope in place. Specifically designed for the M1A Scout Squad or SOCOM 16" with cutout factory top handguard.
