I finally used these out on the range with an M16A2. Most of the time I use them in an indoor pistol range. I am in the Army reserves and I had no problems with the earmuffs coming into contact with the stock. I was also a range safety and if needed I could crank up the headphones and hear everybody on the range, ammo shack, you name it I cold hear it. I wore them for at least a 5 hour time span and never once did they irritate or bother me. I like the fact that if I needed to have a conversation with somebody while firing is going on that I can still hear them since it only cuts out the dangerous noise levels. There are other companies out there but I haven't seen any that come close to the same NRR rating as Pro Ears. They also come with a cable so you can listen to music if you so choose. They are quality made and I highly recommend them.
