Not what i expected - Phase 5 Weapon Systems Inc AR Pistol Enhanced Buffer Spring

This is not what I expected. It was priced lower than most. So I didn't expect it to work as good as it does. But this is a quality spring. You can hear it when you pull the charging handle a bit. But don't think I can hear it when firing. I paired it with a cheap buffer weight and was impressed by how smooth it cycled and how much it reduced the bolt bounce. Highly recommend this to any binary triggers users or anyone trying to reduce bolt bounce. Phase 5 seems to be good for carbine lenght and pistol link buffer tubes as well.
