I have a Gen 1 Sub2k, full Red Lion build. I’ve had it since it was a couple weeks old and had never been fired- about 8 years total. It has spent the bulk of that time in the safe because I cannot get it to eject properly. I get constant stovepipes, and sometimes jams with the spent casing, and the new round in the ejection area. This happens every 4-6 rounds. It has been cleaned and lubricated to no avail. I finally installed the Mcarbo stainless feed ramp this week and took it to the range hoping that was all in the past. It immediately stovepiped on the first round and 8 more times over the next 50 rounds of 115g FMJ. I’ve tried Glock mags, Korean mags, multiple brands of ammo. Nothing has helped. I’m to the point that I want to sell it, and I have multiple buyers lined up, but I’m not comfortable selling it to them with this problem.
I tried to send it in to Keltec, but they told me since I wasn’t the original purchaser, they couldn’t help me. Is there anything I can do to solve this? Thank you for your collective knowledge. I really want to love this carbine, but I can’t trust it right now. I’m attaching some photos of the spent brass.
