Okay, just received new handguards in the mail for my AR15... Installed them went to put one in the chamber (Condition 1) like how I always keep her and I notice the round ejected (now sitting in the magazine ready to be reloaded) has a depress! Consistent with that of the firing pin! I am afraid to reload that round or any other round for that matter, The weapon was kept on safe and locked inside of my safe... The only thing I can think of is a defect with my BCG. Any thing like this experienced before? Recommendations on what to do? It is a DPMS panther AR15, I purchased new in 2008. Thanks!

That doesn't sound very safe. You should get it checked out by a competent gunsmith. 

that's normal.  That's just how ARs are with their floating firing pins.

Awesome! I appreciate the feedback!

Almost all AR15's do that.  You have to rotate your rounds once in a while as the primer can get damaged and possibly fire.  I haven't heard of it happening to anyone, but I wouldn't want to find out.

I had a slam fire when I used Federal small rifle match primers. They are much too sensitive for semi autos with floating firing pins. That was 10 points I lost at 600 yards.

Did you  think this had something to do with a new handguard? 

This post confuses me.................
