Product Details
Suitable for your rifle chambered for 5.56, our .223 is great for everything between range-day plinking to small game hunting.
Brass: Reconditioned or New
*IMPORTANT: Though both cartridges look identical, 5.56 is loaded to a higher pressure than .223, which is why rifles chambered for a 5.56 cartridge can fire .223, but it is not recommended that 5.56 cartridges are fired out of a rifle chambered for .223

I love this Ammo
I bought 4 different types of 223-556 ammo. I just built a new Ballistic Advantage 18 inch barrel with 1:8 twist and it really likes the 69SMK. It shoots this at .750 MOA and I wouldn't say Im the best shot. All I know is it is super repeatable. Love this Ammo.
First time out with the 77 grain through my 16" 1:7 twist Alpha Shooting Sports CHF upper. Some of the other groups from that day. Second trip out, still awesome considering I was using a Holosun ACSS red dot
Very accurate and 100% reliable in my Alpha Shooting Sports 16" CHF 704 Tactical July 2017 special upper with a 1:7 twist shooting their 77 grain 5.56 match ammo. Was getting sub-MOA and one hole groups at 100 yards with a 15x optic and about MOA with a red dot and 3x at the same range. Zero failures and having recently tried their 69 grain .223 rem match ammo was producing about the same results at 100 yards with those optics. Excellent value and quality plus super fast and cheap flat rate shipping you can not go wrong with Defender Ammunition Company.
Crossfit 2 gun competition in Florida. Shooting pistol close range and rifle up to 380 yards before/after or during a smoke session. Great time zero issues with ammo!
Started out with 45 acp from a gun show. Loved them so much I had to order some 223 for my son and me to break in a new rifle build. Only rounds I want to shoot now! Great prices and a veteran owned company too.
I have purchased several calibers. Decided to try .223 69gr smk today. All previous experiences have been very positive needless to say this one didn't disappoint me. If your looking for top notch ammo at a reasonable price this is it !
