In the magazine that came with it can you put a .223 rounds in it or just a 5.56 round?

Asked by Anonymous on Jul 27, 2025

It will handle both..that and being a sixty round is why I purchased..fun to shoot,maybe the binary trigger will be soon

Answered by Anonymous on Jul 27, 2025

When ever you get an ar15 chambered in 556 you can put .223 but not the other way around

I bought one of these rifles a year ago and I gotta buy another. Had trouble with it at 1st jamming but after a few rounds it fired so well. I even bought a 100 round drum and it works so well on it. Two thumbs up!

Loving it great gun for the price , no jams ..has fired every round put through it definitely would buy another

Very Good For The Price

Rated 4 out of 5 stars by Anonymous on Feb 3, 2025

As far as price goes, you can't beat this ar. It can handle both .223 and .556. It can not handle 300 blackout. One thing to note is you can not add a Vertical hand grip due to the fact that the bottom of the mlok is closed, which also means you can add a laser/light only to the side of the mlok. It has a Picatinny rail on top FOr EASy adding of a red dot sight or lvpo scope. Back of shoulder stock is jagged so you will want to buy a pad to cover it for more comfort. The 60 round magazine is very difficult to fully load. Take down pins are also very tight, i actually pressed too hard my very first time disassembling and I broke the spring which was easily fixed by a gunsmith.
