Redneck gunsmithing.....

[Sieg]

This LWRC 5.56 upper was brought to me yesterday with an AAC Breakout 2.0 Comp stuck on the muzzle.

The owner removed the factory pinned flash hider and used the AAC Comp in an attempt to chase the threads.
One problem..... the pin wasn't fully cleared. Another problem..... he's as strong as a Gorilla. This thing was stuck!

I heated the comp and cooled the barrel with compress air, put a tight fitting 7/8" wrench on it and used a brass mallet to persuade the wrench. After multiple attempts I couldn't get it to budge.

After a few head scratching sessions and a trip to Harbor Freight to pick up a $4 21mm impact socket......

I TIG welded the socket flats to the break with MIG600 rod.

Attached my cordless 1/2" impact and it reluctantly came off. Then I took a Dremel with a cut-off disk to the pin remnant and patiently chased the threads with a die and cutting oil.

The new AAC Breakout threaded on nicely and surprisingly it wasn't a loose fit. I'll get it properly pinned after the holidays.

Redneck success.

I had something similar with a RPR recently. Someone put a crush washer that was too small on the barrel with the brake. I ended up having to hacksaw off the crush washer while trying to avoid the threads. I then has a thread chasing file and chased them with that. I have often had to fix bubba's jobs.

I had to boil my AAC flash hider/compensator in water to get it off. Apparently that’s how that thread locker works that they use. It’s stupid strong. I heated it with a torch and beat the fuck out of it and it still wouldn’t come off.
Boiled it in water on my stove for 15 min and came off easy.

When I was younger I did something similar to this with a mini 14 and a flash hider/ front sight. It involved a big hammer and wrench. I'm not proud of it, but it still sets in my safe waiting to be fixed lol.

Ahhh the old gun plumber.

That works for most Loc-tite. Hot water breaks it down pretty quickly.

AAC uses Rocksett. Takes extreme heat but breaks down in boiling water

Is thread locker really needed for breaks? I've never had one come loose, but don't use suppressors either.

Welding the socket onto the brake was smart, and having to do such shows the extremes that need to be pursued in situations such as these. But I gotta ask, that using of the impact to spin it off, I wonder if that is where the fashionable "Gain Twist" concept came from, originally?

"Another happy accident" ?

The impact was the least invasive method IMO, the leverage on the wrench was bowing the barrel. It wasn't a pleasant experience.
Thankfully the gun shoots well after all the abuse. the 14.5" barrel whacks 3" steel with ease at 200yds.

Thatd will buff out

Gain twist actually dates back over a hundred, two hundred years ago. Because they couldn't get rifling perfect with the tools they had, they had learned that a gain twist would compensate for any error.

If you do the reverse, if you retard the twist, you get the opposite. Shotgun sized groups.

As to whether it has any place today is still debated.
