So my A2 went on a diet I weighed my rifle several times and the final weight was 7.8lbs it right around 125oz, First off was the crappy “mil style” A2 brake. Below the welded and pinned brake and about 1” of barrel. I need to face and cut the crown. Most likely I will re crown ala Harry Potterfield style View: https://imgur.com/a/vkWGwpA View: https://youtu.be/b43odFm0mrI I also decided to borrow the Houge round Free float and aluminum barrel nut , will weigh that soon and compare. From another upper. So now my A2 pre 2019 rules compliant rifle should be rules compliant for post rule changes. I also hope to pick up a few accuracy nodes with the free float.
