Thank you sir!

If anyone has any more info on if the stock heatsink actually reinforces the barrel not form anecodotes and hearsay let me know.

Frank literally told me this in-person at SHOT when we talked about the introduction of the Revolution when it debuted. He said he was always scared to do an AR-15 chambered in .308, but had been mulling over it for years. He finally sat down and did the engineering and drafting for it, and committed to move forward.

I specifically asked about hoop stress, because a .473” case head and larger body diameter eats away into the chamber wall thickness when you limit yourself to AR-15 barrel outer dimensions around the chamber, using an AR-15 sized barrel extension.

He said he used the receiver and barrel nut to add to the formula of containing the hoop, with tight tolerances and stronger alloys.

He then supported the durability of the system by pointing out their videos of it being shot in the full auto mode of fire.

However, they were using Russian steel case garbage, underpowered ammo.

My natural question is, how durable is the pressure containment system if run with full-power M80, 168gr, 175gr, 178gr, etc. I didn’t ask him that because he had already let me see up his skirt more than I ever expected. It was a very open and transparent conversation about critical details of the system design.

I don’t think most shooters will ever find the limits with the system, but I’m not most shooters.

I also remember the DPMS people freaking out when one of their reps took a DPMS GII small frame (larger than Revolution with more wall thickness around the chamber) to a week-long high volume shoot course and burned thousands of rounds through it. They immediately seized the weapon, removed the barrel, and sectioned it to analyze the chamber dimensions.

Not sure why they did that, because they ran the GII through pyramid-testing with 10 base rifles, 100k rounds until finalizing the design.

If I am making a range card in advance can I manually change the temperature? It it will update from my phone some how but I would like to be able to enter what I want.

Yes, just click on the box and use the keyboard to input whatever you want.

great idea! several like that in Latin America. reclaiming what China has bought up would really jerk them around. maybe declare Black Rock a foreign agent and fuck with them too?

should be nothing to mull over. stop all funding & supply of all aid-military and "humanitarian". why hasn't this been done? not a confidence builder re what many here thought we were voting for. it does seem that the NWO assets in America are still able to interfere with the work that Trump should be trying to get done. fact is the Ukrainian people might just be better off under Putin. fuck Ukraine.

Send grandpa to remedial marksmanship training.

The stupid thing Zelensky did was try to muscle Trump into providing more weapons to keep the war going, when Trump clearly stated he wants the war to end. No matter what side anyone is on, it was pure diplomatic immaturity.

But it was stupid for Europe to slash their defense spending for the past 34 years. They already were not fulfilling their requirements as well as they could have from the 1950s-1980s, letting the US bear much of the burden.

The fact that they kept their heads in the sand after the 1st and 2nd Chechen wars, then the invasion of Georgia in 2008 was bad enough. After the invasion of Ukraine and annexation of Crimea in 2014, there was no excuse anymore.

This old girl has been around in one form or another since 2011. She's hefty at 10.5lbs without a mag but still has a place in my quiver. Currently sits with a little bit of old and a little bit of new. 13.9" barrel courtesy of D. Wilson.

"Ukrainian President Volodymyr Zelensky has remained defiant in the wake of Friday's explosive confrontation with President Trump and Vice President JD Vance in the Oval Office. He said from London Sunday that he will not apologize that that his country's freedom is "not for sale".

He acknowledged that the public spat "didn’t bring anything positive or additional to us as partner" - however he also said "This relationship will continue because this is more than a relationship in one moment."

"If you don’t have an end to the war and you don’t have security guarantees, no one is able to control a ceasefire," Zelensky stressed in these latest remarks.

He still proclaimed that he remains "ready" to sign a US-Ukraine minerals deal, confirming that his aides are now speaking to Trump's team about ways to move forward on it.

Zelensky says he is prepared to sign a mineral rights deal with the US and thinks the relationship with Washington can be salvaged. —NBC

But the mood from the White House appears to be one of willingness to cut Zelensky off altogether. There are reports that President Trump is mulling cutting off all continuing defense aid to Ukraine."

Americans managing the mineral/gas fields or whatever would be a very strong deterrent to Russia. It's a smart move by Trump, the problem is Trump is the one doing it so all the leftists in Europe (and USA) will sandbag him.

They are trying to do that as we speak.

Imagine UK and Germany trying to muster an army to send to Ukraine to fight Russia though.

What transports will they use?

Who will supply the logistics?

Will their parliaments even sign-off on this insanity, escalating into a new world war?

This is what happens when formerly-powerful nations sacrifice defense-spending in-favor of stupid social welfare programs for migrants.

Quite true. I do find myself wondering sometimes , while SH can be a trove of information, if it is perhaps not the best site for someone who’s brand new to rifle shooting. Very basic questions can get very short shrift here, if not actual derision.

I think the general expectation is that one turns to a forum because they can’t find an answer, not because they’re to lazy to look for one.

I just put one together with an 18” Proof barrel and SA AGB. Went full mass jp bcg and bolt like proof recommends. Also used scs from JP which is just the standard weight and I can’t even get the bolt to travel out of battery when I shoot. Gas is wide open. It takes considerable force to get the bolt to release and eject the shell by hand. I should be getting my borescope today so I can verify alignment. Hopefully it’s something dumb I did. Also running the huxwrx flow 6k. Not sure how long I’ll be using it though. It’s super loud.

I am running the same kit for a year now on both a 18" and 14.5" and I haven't any issues like that, something is off.

TLDR: Try 155hybrids. You'll be happy you did.

Big fan of the shorter barrels.

I'm transonic with my 308W at about 680y shooting 155 hybrids. 11" of barrel, so a little shorter than yours.

I have tested anywhere from 125gr to 185gr and the 155s were the best blend of speed and velocity. Even though the 135gr SMK was moving faster, it didn't have enough back pressure for complete powder burn causing massive SD issues. At 500y it was a problem for me. Moving to 155s stabalized my sanity a good bit. 185gr didn't have enough velocity to make them justifiable.

You will also notice a huge difference in sound based on projectile class used. Assuming you keep powder and suppressor the same, the light for class projectiles will be seriously loud, the heavies much more managable.

With Hornady filing with SAAMI for the 25 Creed, I hope it really gets adopted in the AR10 for the reasons mentioned as well as the fact you can load the heavy bullets to mag length (the heavy 6.5’s are either too long or pretty slow at mag length).

That said, I doubt the 6.5 creed is displaced and the 130 Berger ar hybrid is pretty potent from a gasser

There’s another really sick cartridge for the AR-10 that crushes all the others performance-wise.

It’s what I’m going to do when I get around to messing with AR-10s again, but I’ll do it in the Savage MSR-10 smaller frame I think.

Imagine 5.8 mils drop, 1.3 mils drift, 1104 ft-lbs at 900yds. Case is shorter than Creedmoor.

1000yds +7mil drop 1.5 mils drift 1637fps 964ft-lbs

This would be a question better answered by Garmin.
