I've said that many times and I keep building stuff I don't need.
I have a lower sitting around just have no idea what to do with it. Not trying to build anything I already have. Thought about adding 300 BO, but the ammo prices keep me from adding a new caliber.
Might just build a 7.5" barrel upper for my SBR lower (Has 10.5" barrel right now) and keep thinking on the other lower.
