Bolt won't fully reciprocate after spring locking pin upgrade

After replacing locking pin and re-installing recoil spring the bolt will not reach the rear of the slot that the charging handle travels in. Stops about 1/4" before the locking slot. Can’t lock the bolt back and no full travel of the charging handle. Would my spring be binding somehow? When I try to pull the bolt back and it hits the stopping point it seems like a pretty solid blocking of the rearward movement. I do have the cherry Lifesaver installed also. Removed that and results did not change.

I believe if the pin isn’t seated properly into the charging handle, it is usually the problem. I would try reseating the locking pin into the charging handle a few times and see if that resolves the issue. I have had that happen before and that ended up being the issue.
