I’ve spent about 20 hours fondling the guide rod and spring assembly and my BG2.0
Here’s what I've experienced so far....
Regarding the guide rod and spring assembly not seating into the barrel end of the slide:
There are several mechanical issues that cause the guide rod and spring not to seat into the end of the slide. When that happens the spring assembly cannot be compressed and will not allow the rear spring cap to seat into the slot at the barrel lug.
Issue 1: the end of the spring is not angled flat with the guide rod cap.
Issue 2: the end of the spring is not seated under the guide rod cap.
Issue 3 the spring is not centered around the guide rod cap.
Before attempting to reassemble make sure the end of the spring is seated under the guide rod cap. The first time I used flat head screwdriver to push it. Make sure the spring is centered round the end cap. As you insert the guide rod on top of the barrel and push it into the slide, rotate the guide rod to properly seat it into its collar space. The end cap must be flush or nearly flush with the front edge of slide.
The photo shows the inside of the slide has two collars. One allows the guide rod cap to seat flat with the front edge of the slide. The other larger diameter collar is where the spring will seat. If the spring is not seated exactly in that collar space, the guide rod springs cannot be compressed. On my BG2.0, when I’m reassembling the guide rod/spring assembly into end of slide and on top of the barrel, if the end cap of the guide is not sitting flush or slightly extended beyond the end of the slide, I cannot compress the spring assembly.
To correct the design flaw with the guide rod spring, I removed the main spring by carefully pulling the end over the guide rod cap and slid it off the guide rod. I cut about 3/8” off the twisted end of the spring with a very small Dremel Tool cut-off disc. I carefully worked the spring back onto the guide rod and pressed the end under the cap and very gently squeezed the end of the spring around the guide rod with a pair of plyers.
