Now this is a handy widget!
If you just build an AR-15 or two every once in a while, this might not be necessary. If you are building or rebuilding them frequently, the new Hammer Cage from KNS Precision might just slow the rate at which you fill your swear jar. Simply put, the Hammer Cage takes the spring tension off of the hammer which makes installing (and removing) the hammer pin much easier.
I’m sorry, but I think I’m going to need a video to understand what this is supposed to do. I’m all for products making installation and removal simpler and quicker, but I’m not really sure how this is used.
