I thought it might be a cool idea to share some short cuts or tips with others on efficient ways to build a lower. I am always surprised at the different techniques people use. I always hate the pivot pin install. Came across the universal clevis pin and this video. It works like a charm. Everyone has their own way and process when doing a build. Just thought it would be a good idea to share. Feel free to share ideas others can benefit from [ame="http://www.youtube.com/watch?v=XJNaTjvQaVQ"]AR-15 Pivot Pin Install - YouTube[/ame] Wanna kill these ads? We can help!
