Questions & Answers
The pic shows a gas block and tube with the barrel. The package contains says Geissele Chrome Lined 300 Blackout Barrel. Is the block & tube included

If you look up the part number 05-3428 on Geissele website it comes complete with a custom pistol-length gas tube and Super Compact Gas Block

The listing says the barrel Threads Per Inch is 1/2x28 but that doesn’t sound right. Is it 1/2x28 or 5/8x24?

Yes it is a 5/8x28 and it’s a pistol length gas system not mid.
