Our take: The Daniel Defense M4A1 RIS II is extremely rugged as it’s CNC-machined from a solid block of aircraft-grade aluminum. However, unlike other M4-style railed handguards, this 12-inch free-float quad rail has a removable lower rail segment for seamless installation of M203-type airsoft grenade launchers. Nearly 48 inches of combined rail space lets you attach mounted accessories, effectively turning standard M4A1 AEGs (as well as most M4 and M16 airsoft guns) into a modern and tactical rifle. Lastly, all the necessary parts to install this RIS handguard — barrel nut, screws, washers — are included. The Daniel Defense M4A1 RIS II by Madbull is extremely rugged, has a free float design and is the perfect upgrade part for your AEG.
