And now for my next potential upgrade....
I'm wanting to switch out my existing quad handguard with a rifle length free float handguard. I'll need to get a new low profile gas block and a couple of tools for the installation, but it doesn't look like it'll be too difficult to do.
I've got my eye on this handguard:

I like the look of a rifle length handguard on a 16" barrel, leaving only a few inches of the barrel exposed.
Now I'm upgrading the ****ing upgrades.
