Daniel Defense Frequent Asked Questions

Daniel Defense is one of America’s premier manufacturers of AR-15 rifles for civilians, competitors, hunters, and professionals alike.

Daniel Defense was founded in 2001 in Georgia by Marty Daniel, starting with his vision to create custom rifle accessories for his rifle. At that time, he was unable to buy the rail systems he wanted from another manufacturer, so he decided to design and outsource the production of an M4-compatible rail system.

After one year, at the 2003 SHOT Show (the firearm industry’s largest trade show), Daniel met representatives of the U.S. Naval Surface Warfare Center (NSWC), who incentivized him to submit his product on a bid for an upcoming government contract, issued by the Special Operations Command (SOCOM). Marty won the contract.

Today, Daniel Defense manufactures its products in a brand-new, state-of-the-art facility in Georgia that consists of 300,000 sq. ft. of manufacturing space and office space—consolidating their two previous facilities under one roof.

Daniel Defense remains one of the most popular brands of AR-15 rifles in the U.S., and the business is family-owned and privately held.

Daniel Defense’s primary product line is the DDM4 series, which was the first firearm created by their team of engineers.

The DDM4 V1 features mostly Mil-Spec components but came with an improved Omega X quad rail system that wrapped around the pinned front sight gas block combo. This rifle is very popular among professional consumers looking for a highly accurate, highly durable rifle system that will be reliable in any environment.

For a slightly lighter option, look to the DDM4 V11, which includes a lightweight M-LOK handguard and a thinner barrel profile for enhanced agility and user-comfort.

If you’re looking for a precision-oriented AR15, the Daniel Defense MK12 is their optimized special-purpose rifle. With an 18” cold hammer-forged barrel and enhanced furniture, it has the rigidity and precision to land shots at further distances.

The Delta 5 is Daniel Defense’s first foray into bolt-action precision rifles. It’s an American-made precision rifle system that shares the same commitment to quality and innovation as their trusted AR-platform rifles.

Delta 5 Rifles come chambered in .308 Winchester or 6.5 Creedmoor, have a changeable barrel, a fully configurable stock with M-LOK attachment slots, and a trigger that adjusts for accurate long-range performance. It has a rail section built into the barreled action, so it accepts most standard rifle scope mounts out of the box.

If you’re looking for a premium-grade bolt action rifle at a fair price, the Daniel Defense Delta 5 Bolt Action Rifle is one to seriously consider.
