New Evolution Military Ordnance is a world leader in weapon systems integration that is committed to the research and development of advanced highly accurate firearm technologies. Designed and engineered for military and law enforcement, NEMO produces firearms to excel in the field not secured in a safe. Be Exceptional with New Evolution Military Ordnance. The Executive Order Carbon is a lightweight hard hitting .308 that is sure to make an impact in the field and on the range. Also known as the XO it has gorgeous ergonomic aesthetics that are supremely functional and cut a significant chunk of weight. The 20" Carbon Wrapped Proof Research barrel gives you more velocity and produces groups with scalpel like surgical precision. But the barrel is only as good as the shooter. Superior accuracy is ensured with the addition of a Geissele Super Dynamic Enhanced two stage trigger with the first stage set at 2.3 lbs and the second stage a mere puff of 1.2 lbs. NEMO's recoil reducing bolt carrier group is an astonishing feat of engineering that greatly increases comfort while reducing fatigue. A Quick Switch adjustable gas block allows you to shoot sub-sonic ammunition suppressed or switch back to more powerful longer range ammo on the fly. The 15" Aluminum M-LOK Compatible Modular handguard rail is ready to accept your choice of optics and accessories. Fully ambidextrous, the Executive Order is ideal for any sized shooter in every environment. This is the definition of a do-it-all carbine that is ideal for defense, hunting, and long range precision alike. The XO Carbon will take you, and your shooting, to exceptional new levels of precision.

  • State-Specific Laws
Is it legal to buy a gun online?

Do I need a background check to buy a gun online?

Yes. Even when purchasing online, a background check is required at the FFL dealer where you pick up your firearm (unless you have a permit that exempts you in your state). The FFL dealer will conduct the check before handing over the gun.

Can I have a gun shipped directly to my house?

No, firearms cannot be shipped directly to your home. They must be sent to a licensed FFL dealer, where you will complete the legal transfer process. However, ammo and accessories can be shipped directly to your residence in most states.

How do I choose an FFL dealer for my transfer?

Many online gun stores allow you to select an FFL dealer during checkout. If not, you’ll need to find a local gun shop or licensed dealer willing to handle the transfer and provide their information to the seller.
