No problem. As an owner of a fully-custom glam gun, I recommend building a shitty one first to learn what breaks and what doesn’t.

They’re a bitch to clean. No they’re not. They tear down easily without tools. I can’t think of a part that can’t be cleaned easily. Maybe the gas tube?

If it’s locked up, you can’t knock on the charging handle There’s a button called a forward assist for that specific purpose.

Aluminum gas blocks… Milspec blocks are not aluminum, he’s complaining about after-market, non-standard mods.

The extractor pin will often shatter in place, I’ve seen this on cheap BCGs. It’s annoying, but it’s easily fixable and won’t render the gun useless. You’ll just have to manually clear it.

Lightweight and low-energy.

I keep mine full of piss for just this reason.

But do you really have to show your friends every time?
