In the video for the M3 grease gun you can see the parts they got rid of when they made the M3A1 with no cocking handle. Instead the bolt has a finger hole in the side so you can reach through the ejection port and pull it back. I replaced my share of barrel latches on those guns. I used a small ball peen hammer and a big piece of steel inside the mag well to support the heads of the rivets. They go in from inside the mag well unlike in the video. I was proud of my riveting too. It looked great if I do say so myself.
