So took the cocking tube off. I took a video of me grinding down the weld but the video got deleted. All I did was took a bench grinder and made it flat so the angle grinder didn't jump around too much while cutting it. you might notice a little shelf that's ok as long as you didn't cut too much off the cocking tube. All you need to do is take a file and make it straight. I'm working on the front trunnion now so expect a how to on getting it out
