What upper receivers are you guys using to get a good thermal fit?

Until recently, my goto stripped upper receiver was the BCM blems. A while back, I ordered half a dozen of them. They all worked fine for various rigs and provided a good thermal fit. When I ran out, I ordered 3 more.

Of those 3, two were unusable. One was so tight that I couldn't even get the lapping jig in, much less the barrel, even with liberal use of a torch. Once I got things together, it shot like crap. Gotta imagine there was a whole lot of stress.

On the other, the charging handle, no matter which I used, kept reciprocating.

So, what else is being used to get a good thermal fit?

You'd have them in a heartbeat if she was sporting the body, looks and sucked like a Hoover. Don't try to say that you wouldn't. Once you're done with her the locksmith and counter top can be changed.
Actually she just said she wants a “mommy make over”. Lol

But the kitchen came first … so I’m spending double for nothing 😂😂

Likely the Earliest Marine Sniper Rifle that still exists, from 1909

I have only ever seen one Warner Swasey in either the M1908 or M1913 variation (in person), that was real and wasn't a restoration. They are extremely rare as most had their mounts removed or were destroyed by the early 1930's.

This is one from the last block made in July 1918. It is in the 932xxx serial range. I think the only reason this one survived is it went to a National Guard unit and probably someone took it home at some point. Or Ordnance did sell some in the early 1920's , so that is a possibility.

At one time this one did have a Maxim Silencer on it. There are distinct marks on the barrel where one had been.

Buffer trouble.

Haven't read the whole thread, but that stuck out pretty quick.
As long as we're talking about bad advice pet peeves, when someone is having undergassed problems and the peanut gallery collectively suggests an AGB, that winds me up pretty good. AGB's don't add gas beyond the maximum you're already getting with a standard GB. Come on people, use your brains.
And maybe the nuances of subsonic gun tuning are beyond me, but for supersonic stuff, if your gun isn't running at all, a small change in buffer weight won't fix it. And if it does suddenly work, it's gonna be super borderline. But the go-to gunshop counter advice is always to go from an H2 to an H3 or whatever.
Alright, I'm done ranting.
Yeah, this drives me nuts too. The lesson is ... never ask advise from someone trying to sell you something.

Actually, I'd say that adding an AGB to an undergassed system makes it worse. I haven't seen an adjustable gas block yet that doesn't leak gas from around the adjustment screw(s).

New CHAD clone from Preece.

There's a 1000 conventional, monolithic brakes out there and nobody screams about patent protection

And a 1000 different suppressors that are literally just laser welded baffle stacks

What about this product is so novel that it deserves a monopoly?
CHAD should feel lucky it took this long for competition to come out

not sure if her numbers are accurate, but holy fuck if that is true.

this is how the Us scam $. often have to reduce $ for in state. many other US students have other things like scholarships. foriegners straight up full load cash required. i know for a fact that this also goes on in univ hospitals. they love foreign patients who are required to pay huge bills,cash only. a little known univ scam that lends millions to their holdings.

Trump is back…the “Now What” thread

The FBI transcript of his interview is worth reading in and of itself.

All of these transcripts are worth reading as well

tacom structured barrel

What is the engineering that makes differnt loads at differnt velocities with differnt BC shoot to the same point of aim? Explain that voodoo to me.

If you think of the barrel as one that moves up and down in a sinusoidal wave pattern, projectiles traveling at different velocities will exit the barrel when it's at different positions in that sinusoidal wave. Some velocities will result in the projectile exiting when the barrel is pointing up, others while the barrel is pointing down, which results in a hypothetical vertical dispersion.

If you can "deaden" that barrel by removing, or at least mitigating those sinusoidal wave patterns, aka "harmonics", you reduce the vertical dispersion in projectiles traveling at different velocities.

At distance, you're still going to get vertical dispersion due to differing velocities - that's physics that isn't overcome by a structured barrel.

Leap years are like wild cards. They can be added or subtracted as needed


Plumbers are a close second to what I have seen HVAC guys do. Third place goes to the shitty carpenters. And a lot of the shitty architects that can't do a plan for either of those trades
Can’t we all agree it starts with shitty architects

I Bet This Looked Like A Scene From The Blues Brothers

7 cars famed with five of them totaled. Yep, sounds like Keystone Cops to me. Or, as you noted, a blues brothers chase scene.
I wonder how many crashed into each other.
One slammed on the brakes and others piled in?
I sorta saw one like that on Camp Pendleton. An early morning fog and someone didn't see the traffic lights. One car had stopped for the light and 8 or 9 piled in. I say sorta because I heard it but couldn't really see it through the fog.
