On a side note when I unpacked the upper from shipping and I forgot about the buffer spring and it got tossed in the trash with the box. I have a carbine buffer spring installed right now. I do have the plastic buffer. Everything is installed per the manual. Thinking this may have something to do with my issue.



Wondering if anyone has had a similar issue with the bolt.
The Garrow spring is shorter than stock.
Try clipping a coils off (one at a time) and make sure your carbine buffer is installed backwards in the tube, then the spring and then the plastic buffer.
