cheap/easy mods
You could look at doing all the free stuff. Honestly you're not gonna get huge gains out of it, but it will give you something to do and make you feel productive.
And what is cheap? Are you talking a couple hundred dollars or what? Find a lid and bellows and put them on the ar. Go buy a cutout or something like that.
