458 SOCOM AR15 Lower Receiver Build
Sorry but it is a long video, 41 minutes. First off this video is for entertainment purposes only. I am no expert by any means, but I will show you how I assemble the AR-15 lower receiver. Following any tips or advice seen is at your own risk. I cover stoning and polishing the standard mil spec trigger and hammer which really helps it. Finally assembling the lower receiver.
