Ryohin Buhin Flip-Up Front Sight, SPR Type, Metal, Black, for M4 and M16 Electric Guns

[Compatible Models] Compatible with M4 series electric guns, next-generation electric guns, and gas blowback guns (Tokyo Marui, CYMA, G&G, VFC, etc.) [Foldable Front Sight] This front sight attaches directly to the outer barrel of an M4 rifle. It also doubles as a gas tube and replaces the triangular "Delta Post" (commonly known as "rice ball sight") that comes pre-installed on rifles like the M4A1 Carbine. [Solve Your Obtrusive Front Sight!] The foldable front sight allows you to use low-profile red dot sights that previously got in the way! [Same Height as a Delta Post] The front sight is the same height as a Delta Post, so you can continue using your rear sight. We also recommend replacing it with a folding back-up sight like the "KAC Folding Rear Sight"! [Installation Screws Included] All parts required to secure the sight to the outer barrel are included. Note: A separate hex wrench is required to install the set screws.
