Davidson Defense DefendAR Series AR-15 16" Rifle 5.56 NATO

This rifle is adaptable and has the ability to be used anywhere and under every circumstance. American made and proudly featuring a laser etched American flag on the BCG, the 5.56 Black Diamond series AR-15 billet upper receiver provides great penetrating power. Combined with the ideally weighted 16.5" 4150 CMV with a 1:7 twist rate, button cut barrel by Mercury Precision, you can expect excellent accuracy. 15" free float M-Lok handguard with a front and rear Picatinny rail allowing for a comfortable grip and plenty of space for accessories. The bolt carrier group is our own Davidson Defense 5.56 NATO Slabside made of 9310 steel and nitride, finished at the world class facility H&M. Then MPI and HPT inspected for extreme safety. This Is one of the highest quality BCGs made. The custom engraved lower receiver is also our own. Made with high quality airplane grade 7075 T6 aluminum, this lower receiver is engraved with the Davidson Defense logo and features a manganese phosphate anodized finish.

 We included some high quality components like the Hogue AR-15 stock Mil-Spec Black RBR which can adjust to 6 different Positions, perfect if you’re looking for more stabilization and control. Includes an Omega Manufacturing Mil-Spec buffer tube kit which both attaches to the rifle and works with the bolt carrier group as part of the direct gas impingement system. The stock also features three holes for optimal sling placement.

One of the first things you’ll notice when you pick up this rifle is the Strike Industries enhanced pistol grip. A quality, tactile, raised rubber grip that seems to grip you back, this hits the sweet spot between quality, price, and weight. Adjustable to three different angles so you can find your own sweet spot in relation to preference and application. The subtle palm swell, aggressive texturing, and extended beavertail allows you to get your hand higher up for better control. Includes a secure storage area with rubber end cap to store batteries and oil bottles.


The SI Venom FH muzzle device significantly reduces muzzle flash preserving your night vision. No loss of low light/night vision means the potential to make faster follow up shots, as well as increased situational awareness. The four prongs on the end of the brake are designed to protect the muzzle crown and give this flash hider a one of a kind customized look.

The high quality Omega Manufacturing ambidextrous charging handle is a well crafted instrument that, along with the rest of the moving parts, lets you hear as well as feel the fine craftsmanship of this beautiful machine.


We are happy to include the lower parts kit by KAK Industries, a great U.S. producer of all the precision parts you need to trust.

Trigger is standard Mil-Spec and is a great starting point that can easily be changed as your shooting style evolves.

The enhanced takedown pins are for easy cleaning and repair. Opens up with no tools required.

The forward assist, since rarely used, was removed to save on weight and cost and creates a sleek and refined look.
