I'm hoping I don't need plan B.
By the time I bought a barrel and handguard, I'd be in for around $350'ish which is almost half the cost of the entire gun. That's simply not going to happen.
Plus, I don't want to add velocity. I'm happy with it where I'm at. If this doesn't work, I just keep what I have and forget it.
This alternative cost about $25 plus my time.
Darn, you're right, once you add it up, you are half way to a new gun! It's almost like building a car put of a year one catalog, Ha!
I am really impressed with what you did here. You had a cool idea, and the tools and talent to make it happen. That is super cool, very respectable.
