I recently had my new M305 out and noticed my OP rod guide had moved a tiny bit to one side. I had mentioned it in a previous post. Not that big of deal I will fix that. But I think I found the cause of whats forcing it off centre.
Now the OP rod is just off centre a few degrees and doesn't quite line up with gas system maybe only a heavy 1\8th of an inch. But now it cycles better you can feel it when you dry cycle it. If I line up on the OP rod guide to the gas system it tightens back up and the OP rod lines up nicely. But it feels ####ty to cycle, you can feel it grinding like it has pressure on the OP spring guide making it bind a bit. The issue I am noticing is that when I tighten up the OP rod guide I can see it flex my OP spring guide where the guide is flat and fits into the slot. I feel like the slot in the receiver that holds my OP spring guide is angled that tiny bit off true and is forcing my OP rod guide to push off centre. The OP rod itself is still straight. I recently purchased a new OP spring guide from m14.ca and I tried my old one. They both act the same way. Since the slot seems to be off a tiny bit what is the best way to fix this. File the slot (which is very tight atm) to relieve the tension on the OP spring guide. I am assuming this isn't the best option to have sloppy a fit? Or bend the flat part of the OP spring guide that tiny bit so everything lines up, which is probably easier said than done if its hardened it could just snap on me. Any input or suggestions would be much appreciated.
Thanks.
