Hey guy's I'm having a bit of an issue with my AR and it just started as of today. If I have the bolt closed and try to insert a full 30 round magazine it just slides right out. Now if I have the bolt open and insert the same magazine it locks in totally fine and once I close the bolt it remains in nice and firm. Now If I take an empty mag with a closed bolt it locks in just fine. It's strange because up until yesterday I had a loaded mag (Not chambered) in to give an idea of a loaded weight for a friend who was curious about loaded weight and I didn't have any issues.I've tried taking a few rounds out of the magazine to see if that made any difference and it didn't. I'm wondering if keeping a loaded mag in maybe over did it for the spring in there? Any ideas would be greatly appreciated

At this point I've tried 4 different mags and they all seem to do it. I've taken out several rounds from the magazines to see if that made any difference and it didn't seem to help. Right now i'm using the C-Product 30 round Stainless steel magazines.
I have a bunch of them, c products SS 30 rnd mags, and I have function tested them all in most of my guns that use AR mags, and they all work.. It is just alittle harder to get them to lock up then aluminium mags.
when the bolt is locked back they work fine?

Take a look at the synptoms:
1. Empty mags lock with no problem
2. Loaded mags lock easily only when the bolt is to the rear
3. This condition exists with all your mags
Your difficulty is due to you having to overcome the pressure of the rounds in the magazine against the bottom of the bolt carrier.
To demonstrate this, begin with one round in the mag. If it inserts with no difficulty, increase by one round and try again. Continue adding one round at a time and you'll find that lock-up will become difficult at a certain point.
The 'fix' for this problem of your's is simple - Insert loaded magazine in magazine well, slap bottom of magazine. This is actually SOP whenever inserting mags in a defensive situation - just to be on the safe side.
It's not uncommon for different brands of mags to require different amounts of pressure to seat. If you don't like living with this current situation, try other brands.0
