Nerf Maverick mods, Please tell me some!?

I want to mod my Nerf Maverick I have already done some mods such as the mod that lets your barrel swing all the way out for faster reloading, And full Air restrictor removal. I am interested in almost any mod, i am NOT interested in mods that include using PVC or CPVC pipes. So anything good would be appreciated. I also do not have a dremel. Or epoxy.
