Alright guys, I'm about to dimple my shit for the first

Two, less to mess up and more than enough, blue is more than strong enough red is overkill.

Spin the gasblock upside down so you can align the gasport with one of the screws. With that done, use the gastube hole to line up and mark the centerline on the bottom of the barrel.

Spin it back around, flush up the shoulder and use the mark you made on the barrel to index the screw holes, mark the barrel through the screw holes, take off the block, dimple, then final install everything.

If you have it, Rocksett is the only threadlocker you should use on barrel components. Blue loctite will break down with the heat, red will be really hard to disassemble later if you need to.

Why wouldn't red loctite be preferable in this situation? It's not like you would get into trouble when it comes time to disassemble so as long as you're not being retarded with the blowtorch.

The best suggestion I've heard for red loctite is to use a soldering iron on the fastener.

So here's how it went.

I center punched all three holes flawlessly by tightening down the gas block, taking out one screw at a time, then putting in the tightest fitting drill bit (I have a 115 pc drill index) as the initial punch, which created a tiny divot that was big enough to use as a reference for a larger center punch.

After all the center punches I chucked the barrel in a vise and drilled with a hand drill. The dimples on the front and back were perfect, but I stopped drilling the center one as soon as I noticed it was off. Dunno how that happened tbqh senpai, I'll just have to tighten down the set screws at the ends before screwing in the center one.

>set screw gas block
Nah. Stop this.

Don't dimple unless you have the jig. The only point of dimpling is to align the gas block.

dry fitting

Just use cup screws if your gas block is under a handguard

dimpling is unnecessary for anything that's not going to see hard abuse. people hard thousands of rounds through undimpled barrels with no gas block shifting issues.

Everything seems to check out, I'm satisfied and glad I didn't totally fuck it up.

It's cheap insurance. There's no reason not to do in imho.

I 3d-printed a jig and used a drill press to dimple. Also swapped out the supplied set screws for cone point set screws, and used rocksett on them.

You may be able to save that center one with a punch and some patience.

Good job, anon.

For anyone curious, the BRD jigs are absolutely worth it, especially if you plan on assembling more than one upper.

Only downside is that the gas block pinning jigs are specific to certain manufacturers and I only use geissele blocks so mine was $140. Still better than having to ship uppers off to adco though.

Are those Faxon match barrels any good?
