I have Troy Battle Mags and also Pmags (Gen 2 Non Window) that are both able to take 31 rounds in them, but when they do have 31 rds they won't load into my AR15 when the bolt is closed, but if I put it in when the bolt is open it closes, and will the round (#31)

So really, these are 31 rd mags.

Is this normal?

They are 30 round magazines. Don't try to push more in...

Only load 28 rounds in Pmags or they might fall out of your gun during a carbine class drill which can be embarrassing.

Fully understand, but I wasn't counting when I loaded them up, 31 wasn't any tougher to load than 30.

These are 30 round mags.  You can load 31 if you really push it, sure, but the mags aren't made for that, and over-loading can result in feed issues.  Some guys only load theirs with 28-29 rounds.  If you want 31 rounds in your AR, load a mag, charge it, drop the mag and top it off with the extra round you just loaded.  That's  30 in the mag +1 in the pipe.

Thanks for the info guys, I wasn't trying to say I want to be able to load 31 etc, i'm just relatively new to the AR world and was curious, and got my answers.

Thanks.

31 will over compress the springs and damage them.

i run 30 rounds is ALL modern mags with zero issues <they are designed for them with proper springs> i haven't run 28 rounds in a mag since the 80's.

Thanks for the comment... dick. I put Noob in the title just for people like you.... but maybe your reading and comprehension skills aren't up to snuff.

Me being a noob is exactly why I came to a forum to ask the question, most times, there are nice folks, who realize everyone has to start somewhere.

I've used some ar15.com information on helping me assemble my first stripped lower, and upper etc to become more familiar with the platform.

Guess i should have expected a-hole comments as this is GD.

I know old guys that *NEVER* load more than 28 rounds in a 30 round magazine.
Or 18 rounds in a 20 round magazine.

It's what old people do.

They remember when USGI mags back in the day were tight on the 30th round, and did not give much play to allow seating on a closed bolt, so the geezers started only loading 28.  It was further complicated because they were too stupid or weak to train to fully seat a magazine... they'd just push it in softly and call it good... instead of giving it a good slap to insert.  Then when it would fall out - they'd be embarrassed and swear to everyone they slammed it in there... it just wouldn't seat.

Later, using magpul or the new issue followers this no longer was an issue on USGI magazines, and was never an issue with PMAG's which have plenty of room to seat on a close bolt with 30 in the mag... as evidenced by the fact they can actually accept 31 rounds.  However, because of fat has-been instructors continuing to preach and teach the old ways of the force.... this practice has continued in some misinformed circles.

Actually left over from WWII.  A 30 round magazine was manufactured for the Thompson 45.  If you loaded more than 28 rounds in the magazine it tended to fall out of the gun when you fired the first round.  The 20 round and drum magazines worked fine.

It can depend on the dimensions of the lower as well.  Some of them seem to have the mag catch just a tad bit higher.  I have one AR that a 30 round mag, loaded to 30 rounds won't push in quite far enough engage the mag catch when the bolt closed but my other ones will do it no problem.

I have to beat the shit out of a fully loaded PMAG to get it to seat in my AR's.  Not the best option for speed.

With vitriolic responses like his, I am not sure he has the self-control required for discussions in the technical forums.  

The response that angered him is correct.... and well suited.  While everyone DOES have to start somewhere, they should spend a LOT more time reading, before talking.

Especially when THIS LINK will tell you all you need to know.  

I have no problem with people asking questions like this... but you have to accept that if you don't want to do the work searching and reading, and you want your question answered right now.... you have to put up with a little shit.  Just how it works.

Anyone else ever notice that sometimes how many you can get in a magazine will change depending on which ammo brand you use. Thicker brass?

My H&K AR magazines let me overload them too.
