An AR-15 firing pin cannot get stuck in the foreword position unless it is broke in two.
When the bolt carrier is blown back off the bolt to unlock it, the firing pin is mechanically retracted and is shorter then the bolt body.
The only time it is able to reach a primer is when the bolt is telescoped back inside the carrier and fully locked in the barrel extension.
Doubling can be caused by only one of three things:
1. Defective trigger / disconnecter.
2. Soft or too sensitive primers getting set off just as the bolt is fully locked shut and the firing pin is able to fly foreword and hit it.
3. A very light trigger, combined with a relaxed hold on the gun, allowing the gun to "bump fire" against your trigger finger.
