555JM 10 Posted January 3, 2014 Report Share Posted January 3, 2014 The top (dust) cover on my unconverted '09 from TGI is so loose it rattles when you carry the rifle around. Tried another dust cover and it was the same. Thinking of pinching the sides of the cover in toward the rear (button) end. Before doing that, thought I'd ask to see if someone has a better fix. Tried search, but not so good at that & came up dry. Quote Link to post Share on other sites
Sim_Player 1,939 Posted January 3, 2014 Report Share Posted January 3, 2014 (edited) Strange. Can you try a different recoil spring assembly? Has it always been this way? It sounds like the rear trunnion and rear sight block are too far apart. Maybe several hundreds of an inch. I found a video on Youtube under "AK Dust Cover Loose" He claims that his gas-block hole was drilled over-sized causing the recoil-spring to slam backward elongating the rear trunnion rivet holes. He sent it back under warranty. Edited January 3, 2014 by Sim_Player Quote Link to post Share on other sites
BigChongus 765 Posted January 3, 2014 Report Share Posted January 3, 2014 Is there a gap between the dust cover and the RSB by the barrel pin on the left side of the receiver? If so, I'd agree with Sim. In this area: Quote Link to post Share on other sites
555JM 10 Posted January 4, 2014 Author Report Share Posted January 4, 2014 (edited) OK, I fixed it...for now anyway. Tried another recoil spring assy. per Sim. Helped some but noticed the cover still very loose at the front. So I put the orginal spring assy. back in the gun. To fix it, I used a metal fluting plier that was in my tool box. Went at it as though I was going to use the tool to deepen the dimple that's on the front of the cover. Gave the tool a firm squeeze and then checked the fit. It was about perfect. The tool didn't deepen the dimple noticeably, it just changed the curvature on the front of the cover to a slight interference fit in the groove under the rear sight block. The gun is nearly new and only has sight-in rounds through it. The cover has been loose the whole time. If the problem recurs, I'll go look for that YouTube video. I think a few tolerances stacked the wrong way on my gun. Thanks. Edited January 4, 2014 by 555JM Quote Link to post Share on other sites
555JM 10 Posted January 4, 2014 Author Report Share Posted January 4, 2014 I found that video, Sim. The problem that guy had was much more serious than what I had. With the gaps his rifle had, front & rear, it looked like something in his receiver was stretching or being battered. Mine has very small gaps, front & rear. Quote Link to post Share on other sites
Sim_Player 1,939 Posted January 4, 2014 Report Share Posted January 4, 2014 (edited) The fact that the gun is still basically new is a great sign. It's probably just a "parts fit" issue and a little metal bending sanding or filing is normal. I just finished building my first AK from parts and almost EVERY part of the rifle seemed to require "minor fitting". The dust cover doesn't really do anything, concerning function, so as long as it's not making noise, or falling off, you're fine. I love an easy fix.
