Didn't they say a truck rolled over a bag of guns at one point and the cav arms lowers were the only ones undamaged?

I can’t find it now but there was a video where someone shot the hell out of a GWACS lower with another AR, then they built an AR using the shot-up lower and ran the hell out of it.

They do a lot more than just shoot that poor lower. Run it over with a car, use it to do pushups, all sorts of dumb poo poo. The shooting it is at the end and is obviously the final bit.

Shouldn't be. You should be able to flick your wrist while holding the BCG and the bolt should come out, then push it in and flick it open again. That's how I test if it's lubed sufficiently.

I think it's fine if it's tight when brand new. The gas rings will be pretty tight. As long as you can still cycle the action by hand without too much effort, it should be fine.

A rifle for home defense seems a little curious to me. I use a handgun with JHP and a separate Surefire flashlight. Don't like the idea of necessarily having to point the gun at someone/something to illuminate them.

But home intruders aren't high on my list of concerns. Live in a decent neighborhood and I've got a big dog.

The nice thing about bright lights is that you don't have to point it directly at something to see what it is. But having a separate light while working a handgun is perfectly fine.

How precisley they were cast/ any bubbles in the material stuff like that. Maybe the 3 panel of your d20 is a 10th of a millimeter too high compared to the other panels. Maybe that gives it a tendency to roll more with the 3 panel being on bottom and making the corresponding reverse panel up more likely by .37%. It was NUTS man how offended people were getting

Oh yeah. If you’re not roll-testing every single die a hundred thousand times to have a statistically valid sample size for accuracy verification, you’re NEGLIGENT.

Yeah, that's the style. Maybe Colts are going to fetch dumb prices now that they've stopped production? I just thought it was a neat piece of po-surp, but I probably wouldn't have even bought it at $1000.

The shop I work part time at has been fielding requests for ARs. The most recent one:

Customer: “I need an AR, what do you have?”

Me: “We have one complete Aero lower and four different uppers available. Cheapest combo would be $600 out the door.”

Customer: “Why would anyone buy from you when I they can get an AR from PSA for $350?”

A fair question... although it looks like the cheapest complete AR on PSA right now is $579, but whatever.

Ugh. This reloading component shortage has me wanting a dedicated .22 upper.

But I already have an M&P15/22.

But I can't use it at Appleseed.

And I have no idea if it's accurate enough.

But I may never shoot another Appleseed.

A CMMG bolt and dedicated .22 barrel combo are $350, and I have all the other parts I'd need to build it up... except the adapter to use 15/22 mags.

Help me, I don't know what to do.

Magwell hold is also an old school method that was a method for crosstraining on platforms for CQB.

And my boss's boss does it every time on the rifle qual, and he wraps around so aggressively that he blocks the ejection port of his M4 every time. And causes a stoppage. Every time. Every time we go to the range, I warn him not to do that, but he does it anyway. I should install a VFG on his gun just to give him something else to hang on to.

As far as I can tell, almost everything not strictly military-related went from ITAR over to the Department of Commerce's "Commerce Control List" earlier this year, with the goal of making licensing requirements less onerous and license exemptions more broad. So, thanks, Trump?

...I understand how to check POI.

I was trying to find out if anyone had an intuitive sense for whether or not PMC was likely to have enough of a POI change versus the other three rounds I listed to be a concern for non-precision applications inside of 100 yards.
Like, is this a "you probably need to fine tune it on your next range trip" level of variation or a "assume your zero is meaningless and restart the process at 25 yards for safety's sake" kind of thing?
I know I've seen major shifts in POI for .22LR at 50 yards, and I know the .308 I've shot is usually within +/- 4 inches at 100 yards even with major shifts in bullet weight.
But I have no intuitive sense of what to expect with .223 because none of the .223 I've ever shot has had a noticeable difference in POI, but this is a brand I haven't shot before.

It's going to be closer to your .308 experience; .22LR is in a very different class, ballistically speaking. The few times I've zeroed with 62-grain ammo and switched to 55, for example, it's been within a few inches at a hundred yards.

This is apparently Wilson Combat's primary insurance against OOB detonations. A friend of mine got their 9mm AR and it was so hard to cycle the action by hand that I thought it was broken. Then I thought there was no way it would cycle with target ammo. But sure enough, it worked fine.

Anyone here have experience running a Simunition 5.56 drop-in bolt? I’m having a problem with mine. I am doing a two-day shoot house class and my first two runs went well. Then on the third run I pulled up on a threat and the gun went click.

Long story short I transitioned to the pistol and finished the run. But every subsequent run that I tried with the M4, same thing. Chamber a round but get a click instead of a bang.

I did a little troubleshooting and discovered that it wasn’t going all the way into battery, not even when hammering on the forward assist. It just springs back from battery a hair, like the extractor isn’t slipping over the case rim. This results in the firing pin not making contact with the chambered round.

I’ve taken it apart and cleaned it, and I see nothing wrong. It wasn’t even that dirty. I even disassembled the weird Simunition bolt and saw nothing amiss. The firing pin floats freely and protrusion looks okay. The extractor looks in-spec and clamps onto a shell rim if I manually place one on there and pivot it down against the ejector. And the extractor moves normally against its spring. There’s no gunk on the bolt head or in the chamber locking lugs.

I’m sort of at a loss right now. It was running fine and then all of a sudden it wasn’t.

I found another clue to the Simunition problem: the extractor isn’t catching the case rim, which is causing the ejector to push the bolt out of battery a little. Time to disassemble and clean it again.
