Yep. Nuttiest thing I've ever seen go wrong with building a gas gun. I think they drilled the pilot hole in the block, and it was Friday at closing, and "get all your parts to the guy that does the Phosphate treatment on Monday mornings!" - and punch out for the weekend. "Oopsie, forgot to finish that gas block before I left! Oh well..." I'm adding "inspect gas BLOCK gas port diameter to my own build checklist. 1/8" drill bit should fit, every single time. It was frustrating.

Did the strangest Diag over last weekend that I've ever had to do on a gas gun. It would fire, and not cycle. The BCG would move a little less than an inch and a half. 16" midlength gas, .223 Wylde 1:8" twist barrel, 0.750" gas block journal, gas port diameter range of 0.078" to 0.083" - it was drilled 0.078", and should be enough. NiB BCG, Carbine recoil system with a 7.000" internal depth, 2.750" AR15 Carbine H3 buffer, 5.4 oz. Known good (new) carbine recoil spring. So, fire, no ejection, BCG movement less than 1.5" total travel. First step, gas port goes to 0.082" (closest bit I had there to max in the range). Fire again, exact same results, minimal BCG movement. Have to use the charging handle to cycle the action, eject the case, feed new case, and fire again. Next logical solution, install the H1 buffer I had in the toolbox. 3.8 oz. EXACT same conditions, same BCG movement. Next, break out the tools, and take the buffer apart - go to the extreme end of the spectrum. Empty aluminum buffer body, nothing inside, bumper reinstalled... EXACT SAME firing condition, same BCG movement. Okay, so this IS NOT a recoil system problem, not at all. It's Gas System, and gas only, and the gas port diameter is right. So, gas tube is bad. Strip the handguard, pound out the gas tube roll pin, remove the gas tube... Measure the port size and port location. Port size is 0.125" (correct), and it's location from the end of the gas tube is 0.600" (also correct). WTF!!! Remove the muzzle device, remove the gas block, which had red loc-tite on the screws. That took a small portable propane torch. Get those screws and that gas block body hot, remove screws, set the thing down to cool. It took two full Coors Lights for it to cool down enough to remove, and off it came. Looked at the barrel, and burn marks (carbon buildup), and it just looked weird. Carbon blown all over the place. No real distinct carbon ring around the gas port in the barrel, like you'd usually see when you remove a gas block - carbon was just everywhere under the gas block. Hmmm... Getting frustrated with this thing. It was built from good (reputable) parts, but I didn't understand the functional (malfunction) description until I knew how far that BCG was traveling. Or, NOT traveling. Looked into the barrel portion of that gas block, to look at the port in there, and it's the smallest fucking thing I've ever seen in a gas block before - and this is a YHM steel gas block. Those dudes make some damn good parts, FFS! That port diameter in that gas block was 0.0525". !!! 52-thou !!! It's supposed to be 0.125" !!! Went to drill it up to 0.125", and that is some hard metal to drill. I broke the bit, ran the broken jagged piece through my left thumbnail, and bled everywhere. Normally, fingers and toes gross me out, but this just made me more determined to get this block done. Didn't want to go bigger on the bit, over 0.125", so I went down to the next size, and that was 0.119". It's larger than the gas port diameter in the barrel, so it won't matter if it's smaller than 0.125" for this gas gun. Owner had it perfectly centered up. Reinstalled everything, tightened it all back down. Reinstalled the H3 buffer. We'll find out next week sometime how it does, when it gets taken back out. I'd like to be there, but don't know if I will be. I'll report back on the results... I already know it's gonna work flawlessly, and that was the only real issue going on. The small-ass hole in the gas BLOCK was restricting flow so bad that no matter what was done, there was only enough gas available to move that BCG about 1.5"... That sucked.

That's badass - evil, but badass.

Nobody likes a quitter, Doc... Straighten up and fly right...

Here's what was banned by CMT. I have a feeling they've Bud-Lighted themselves with that move. We'll see. Hard lessons are hard to learn...

This just turned him into Aaron Lewis-level category, right here. Hands down to Jason Aldean. Here's some Aaron Lewis, if you're not familiar with that name... (Smack yourself, if you didn't know... )

Nothing sucks, from Alice Cooper. Go smash your nuts in a vise.

It's ALICE COOPER.

Arizona loves Alice Cooper so much, we just released a license plate honoring him. He's Legend.

You will not "need" a jig and drill press to do a Geissele Super Gas Block - a hand drill handles that task quite well, and it's incredibly easy. I've done 1/2 dozen of those with just a hand drill, free-hand, no jig necessary. It's the design of that particular gas block - wide, flat area for the roll pin, big fat pilot hole is already there, and all the way through the gas block. Just use a good bit, go slow and light pressure, like you were upsizing a gas port in a barrel.

I won't lie - lot's of summers here on a streetbike. When it's this fukkin' hot, I had a mesh jacket on, with all the padding - shoulders, back, elbows, kidneys. Just something to keep me from sticking to the pavement, if I went down and had to stay there, not moving. Full kit, though, besides the jacket material. Boots, gloves, fullface helmet. You had to have gloves, because the griips are too hot to grab without them. Just wasn't practical, or (healthy) safe to roll in a leather heatmit around your upper body, that won't breathe at all, and pass no air. My $0.02 on riding in the oven.

This is my preferred staking tool. Works great on gas blocks, but get the right angle. It "mangles" castle nuts and endplates perfectly, as well.

The entire Bud Light Debacle, clearly explained by Al Bundy...

Fuk that donkey - he needs to go back to where ever he came from... Yeah, when it's like this outside in the summer, asphalt can hit 170*~180* surface temp. Don't ride your motorcycle without wearing a leather jacket... Which is kinda like an oxy-moron... It's fuckin' 115*, and YOU want me to put on a leather jacket?!!? Hey, make your call - two kinds of riders out there, and only two... The ones that have been down, and the ones that are going down...

I'm already at 5. You will make it 7 or 8...

Libs: "We don't like this hate speech, and he's right leaning. This is violent vitriol, mean to stir people up and cause problems... " Yeah, whatever. When was the last time you fuckers complained about the lyrics in a fuckin' Gangsta' Rap song?! Yeah, NEVER. Go fuk yourselves.

Blow this one up. "Cancel the Cancellers." Fukc them, Right in the neck.

It's getting painted when you get down here, before the shoot. Or, you stay another week to make the match the following Saturday, and it gets painted before the match. Painting takes a full 24 hours. Arrive "one day earlier than one day early" if we're painting before the shoot.

I can have a LaRue MBT-2S trigger waiting for you whan you get down here. I'll be getting them 5 at a time, so they're $80 each. If that interests you. I'm sure they're not documenting what trigger you install. Or, are they?...

So... It's been pretty crazy here. There was a 49-year old record, from 1974, with 18 days straight at/over 110*. Well, we smoked that. I think it's day 21 now. There's an end in sight, but it's over a week out now. Fun. Somewhere in the last few days, it was 119*. That was a record-breaker for that day, somewhere in the past. Don't know when it will end, and "just be 109*," but it won't matter, because it'll be 110*+ the day after that, anyway. August here usually sucks just like July sucks. We're blessed that we had a very wet winter, and a June that was like no other. It was well into June before we even cracked a hundred. That was a blessing. September can't come soon enough, and October can come soon enough after that. Oh, broke another record at the beginning of the week - we broke "The highest low-temp ever recorded..." I think it was Tuesday night/Wednesday morning. The LOW that day was 97*... You just can't make this shiit up... Here's today's forecast, for CG, current analysis by WTForecast...

Indeed, it works, and works very, very well. I do it on the lo-pro gas blocks once I have the gun figured out. Once the gun is straight - completely, totally - that's the last step I make in "finishing" the gun. I forgot to answer that part, and I no-sheit woke up last night and thought about that. Of course, I was tired, and said "I'll get back to that tomorrow." ...And I was back out...

This is badass. Plus, it's history. That makes it 2,999 times more cool.

If you wanna convert over to that, I have a pretty solid way of attaching one. I wrote it up here awhile ago, and I'm getting ready to mod another one for @JBMatt. Here's the writeup, on what I do to them. It's simple, really is.

Your guns will hate 62gr, if it's the M855 / SS109. 1:9" twist A1s hate that stuff. That ammo was developed for the A2, 1:7" twist. 1:8" barrels don't have a problem with it at all. Some 1:9" barrels like it, most don't. Talking M855 / SS109 ammo here.
