I have this with two followers. One follower is for five rounds, and the other is for nine rounds. At the range, I found the spring weak and caused failures. NONE of my many other magazines have failed. While I have this just for hunting, to follow the KY state regulate of magazines limited to ten rounds, this is close to worthless. I have dozens of firearms, several of which are AR's. I have tons of military experience, both enlisted (combat medic) and as an officer (combat engineer, recon leader, and light infantry commander). IF you have to use a limited magazine, look for something else. IF you do go with these, realize what they are, close to worthless.

bought two of these one will hold five but will jam the other one will hold four and jam using various types of ammo thought about changing springs and followers an expensive fix plus new mags just to hunt legally.

After a little work on the Green Follower, by cliping a little off on the end. Now my Mag holds 5 rounds and doesn't jam anymore... I'm going to buy more, Lots more.

I bought this mag so i could legally hunt with my dpms .204. MJR was right in saying only load 4. mine hasn't jamed with 5 but it's just too tight and actually pushes the case up so hard it dents the shoulder on the top of the mag as it feeds. I've done a little filing on it but it's just easier to chamber the first round and keep 4 in the mag. All in all it works like you want it to.

Very Very nice magazine. I don't know what the previous person was talking about not putting in 5 rounds in it at a time? I ran 5 rounds in it all day, ran wolf, hsm, rem, ultramax. 5 rounds at a time through it all day long and NOT 1 jam. Good buy.

Came in good condition. I would not put 5 rounds in it. Keep 4 that seems to work the best. 5 jams the spring. Other then that it is awesome. Perfect mag for zeroing or hunting!

I bought this mag a few months ago. When i first took a glance at it, it was in very good condition, minor scratches to the outside of the mag. The magazine fit my bushmaster x-15a2 and i am sure it will fit other brands of ar-15 or m16 rifles. The 5 round clip worked well and did not jam often. The only thing wrong about this magazine is that it has a rough outside to it, almost like a sandpaper type of material. Nothing wrong with the material, otherwise i would give it a 5/5 rating
