A tip that might help, I replaced my forend and had to use Map gas torch to break lose the barrel nut, just a thought.

This is where I wimped out on my "build" and just bought a PSA fully assembled upper.

It's not that it's so terribly hard to build an upper, but it requires specialized tools, torque wrenches, and clamping fixtures that I would have spent almost as much in tooling to build an upper as I would just buying a completed upper.

If I were into swapping handguards, gas blocks, barrels, or building multiple ARs, the investment into the specialized tooling is justified.

For my single AR, a stripped Poverty Pony lower, and a completed upper with a lower parts kit from PSA was the extent of my commitment to building an AR.

Going by the old adage that "two is one, and one is none," if the government ever asks, the number of ARs I own are 'none.'

If it can’t be fixed with a cold chisel, vice grips and a hammer, I should not be working on it.

Bump (not stock).

We don’t recommend trying to install the extension onto the barrel yourself.

Then what is the point of a how-to video?

This is extremely important information for freedom-loving Americans who choose to own and operate one of the most finicky, least reliable, malfunction-prone and inaccurate rifles ever made.

I have thought about doing this, albeit I have 5-6 non-firearm projects to
preform before attempting to go to blackout.

PS: Don’t I need to fill out a ATF form before I do this?
