6 5/8 or 6 3/4 pistol gas tube

[C. Stevens]

So I'm changing the barrel on my 300 blackout pistol and while disassembling the gas tube from the block the carbon has it so tight that I'm just going to leave it. I ran to my local gun store and purchased a pistol length gas tube from bootleg Inc. I noticed that this tube is 6 5/8 in and the noveske pistol tube I had is 6 3/4 in. Will they both work?

Use the same length as before as it worked.

Clamp the tube in a vise where the tube bends. Spray the block with some penetrating oil and let it soak for a bit. Twist the block back and forth, then tap the block free of the tube with a hammer and brass punch.

I definitely did that and I couldn't twist, when I smacked it with my brass hammer a few good times it bent the tube right where it goes into the block. I decided to abandon that idea and just include the tube and block with the barrel when I list it for sale. I believe I was overthinking this whole thing in hindsight. I ended up putting the 6 5/8 tube in, checking for bolt closure and test firing. Seems to be fine.
