Daniel Defense M4A1
The Daniel Defense M4A1 is a 14.5-inch 5.56 NATO carbine with a pinned flash suppressor and the RIS II quad rail. The rail design has been used in SOCOM's SOPMOD program.
Daniel Defense builds its rifles in Black Creek, Georgia, and it's known for cold hammer-forged barrels and well-finished AR-pattern rifles. The M4A1 is its take on the classic special operations carbine, built around the RIS II rail, which U.S. Special Operations Command has used in its SOPMOD Block II program since 2005.
It's chambered in 5.56mm NATO with a 14.5-inch M4-profile barrel, cold hammer forged from chrome moly vanadium steel with a 1-in-7 twist. A Daniel Defense flash suppressor is permanently attached, bringing the barrel to the legal 16-inch length for a rifle without an NFA stamp. It runs a carbine-length direct impingement gas system.
The RIS II is a Picatinny quad rail machined from 6061-T6 aluminum, with mounting space on all four sides. It's the rail that gives the M4A1 its familiar look.
The buttstock rides on a six-position receiver extension, and the trigger is mil-spec. Daniel Defense adds an independently ambidextrous GRIP-N-RIP charging handle and an enhanced flared magazine well. An H buffer is included.
It measures 31.5 to 34.75 inches long and weighs 6.74 pounds. The aluminum parts are hard coat anodized, and the steel parts have a heavy phosphate coating. Daniel Defense includes a hard case, and the rifle is made in the USA.
If you want a faithful commercial version of the SOPMOD-era M4A1 carbine, with the RIS II rail that defined it, the Daniel Defense M4A1 is a natural choice.
