This is gonna sound really newbie, but that's alright because I'm new to nerf modding. I've gutted the AR and stretched the spring on my Recon, and I put it back together and it shot fine. I recently took it back apart to cut back on some loudness issues, but now when I put it back together the slide is jammed and will not pull back. From what I can tell everything is in it's proper place, but I can't seem to find the answer. Can anyone offer their advice to a beginner?
