I knew I was gonna have to upgrade this rifle but I was hoping to get a little further into the season. After about 230 BBs shot, I'm having an issue with spring compression.

When pulling the bolt back to compress the spring, instead of the spring remaining compressed there's a skipping feel and sound which leaves the spring in the same state of resistance as when pulling the bolt. I have not had a chance to open the rifle and have a look but I figured someone here might point be in the direction of what to look for first. I was thinking the trigger box was probably the issue as I presume it's what's normally holding back the spring in the compressed position. Am I right to assume this?
