I'm wondering if anyone out there could help me figure out this issue with my VSR 10. It's a basic CYMA 701B with nothing but a spring, spring guide and piston upgrade. It's been perfect for weeks and now for some reason I am having an incredibly hard time pushing the bolt back.
It got stuck the other day so bad that I had to tap it pretty hard to force it back in as I didn't want to leave the spring compressed.
I keep seeing posts about the spring guide stopper potentially being the issue, But being so new to this I don't really know why it would be doing this.
Everything is nicely lubed where it needs to be. Nothing is overtightened. Everything seems to be aligned properly. Have been really enjoying this rifle, and I have been studying it's internals quite a bit so I can strip it and clean it regularly and upgrade it which I really do like doing.
If anyone has had this issue or knows what could potentially be the cause please let me know. I was hoping one day to actually take it to an event. I have a Specna Arms M4/AR15 which I should probably use first, but would like to try sniping at some point, but not like this :(
Any help would be much appreciated :)
