Is this normal procedure? 1. Insert new magazine 2. Pull back charging handle 3. Bolt stays stuck open 4. I tap or pull on the bottom of the magazine and then the round fully feeds and the bolt closes I feel like something is wrong and the round is getting stuck when I pull the charging handle Or is "normal procedure" to pull the charging handle back, then push it forward to load the round fully? I thought it was supposed to feed fully just by pulling back the charging handle and releasing?
