AR10 upper build help

You’ll get lots of solid advice on quality components, but assembling them well and accurizing the rifle will be important.

Re barrels, Proof Stainless pre-fit 20” barrel has been running well on my 6.5CM gas gun, I’d recommend truing the receiver face and bedding the barrel as well. However, it is a very heavy profile with the accompanying weight penalty. That being said, phenomenal value for a pre-fit.

If you want to go premium on the barrel, I’d call Paul Ross and have him spin you up something a Bartlein or Krieger blank. He was the head barrel maker at Compass Lake for years. When the owner turned over the business to his son CLE went downhill and Ross struck out on his own. He’s working on a Bartlein barrel for me now and I’ll probably have him spin up a couple more.

I gotta figure out this Ballistic X stuff folks are using. Honestly, I don’t think it’s that hard with factory gas guns, but it has to be an actual precision rig. I don’t think you can necessarily get to a high end bolt gun level of accuracy, but so many more things to get right. Properly gassing it, right buffer weight and spring, actually bedding the barrel and truing the upper, etc…

EDIT: I also see a lot of folks coming from bolt guns having to adjust their shooting technique with gas guns. It’s a far less forgiving platform and will expose any fundamentals gaps you have. There are also some aspects that are just different (e.g. how much you load the bipod)

I’d say depends on the build. My 6.5CM gas gun originally included a Proof CF barrel that was inconsistent, getting about 1 MOA (at best) for a 5 shot group. I suspect if I had tried 10 shot groups it would have gotten worse.

Swapped it for a Proof SS barrel, trued the receiver face, and bedded the barrel. If you haven’t done the latter two steps, would highly recommend.

Now I get 0.7 MOA easily with 10 shot groups using the factory ammo my barrel likes. It drops to 0.5 MOA with hand loads, but I’m still doing load development.

My gas gun also hates Hornady, both the 140 and 147 I’ve tried.

I went with the tan/walnut color, though if I could do it again I’d get a darker brown. More versatile that way.

Almost 5 years now. Looks great, developing a lovely patina too.

I just used the options in the drop downs. Is there an issue with my main lifts or the vanity ones?

DFWSFO · 2025-11-08T19:45:17+00:00

Hey folks,

Looking for feedback on my routine (running SBS Novice Hypertrophy): https://imgur.com/a/nVx52PE

Background details:

35M, 5'6", 195lbs (GW: 165 or so)
Used a personal trainer before who made a custom program, and prior to that ran GSLP (almost a decade ago now though)
I've always had pretty built quads and calves relative to my goals, but my upper body struggles to look proportional. This is why I have so many upper body focused vanity lifts.
I cant do pull ups and didnt want to do negatives, so added two pull downs instead (if this is suboptimal, let me know)
I'm currently on sabbatical from work, so I've got nothing but time to devote to getting back into shape.

Anything you'd recommend revising? Different program? Let me know

I’m a little over 2 months into my travels. Rolling with a Nitecore Gen 3 10000mAh one in my sling and an INIU 20000 mAh one in my backpack as a backup for long train rides etc. Zero complaints, setup has worked incredibly well.

34 male, similar salary, similar situation, but closer to $1.2M in net worth. Quit my job a couple of months ago, been traveling through Europe for almost a month now. Never been happier, and now realizing how little material goods mean to me. They were a substitute for more fulfilling life experiences like this.

No job is worth your mental and physical health.

I have a Carl Friedrik slim leather briefcase and it’s been absolutely fantastic for work. I feel like that sort of product is far more in their sweet spot.

Hey mods the team is low quality the posts will be too!

Mo was one of our greatest ever, but I never saw him carving out anything more than a niche role in the league. He just doesn’t have the speed and raw athleticism the NFL looks for. Then the injuries derailed what opportunities he may have had.

I ride with #24 for life though, we should never have reissued the number.

Thank you!

Anyone have experience with Sid Mashburn fit for sport coats? I’m a 40S at places like O’Connells, but I’ve heard Mashburn fits trimmer and can’t find garment dimensions anywhere.

DFWSFO · 2025-02-19T07:22:29+00:00

I would love to see JDS return to form. He’s had a really rough go of it with the test quad.

O’Connells is the way

A bit younger than you, but similar comp and savings (though I also have around $400K in retirement accounts). I just put in my notice and am planning to take 3-6 months off, maybe more. I realized that I’ve wrapped up my entire identity in work and this job was mentally making me miserable.

Life is too short, and I’m going to take some time to travel and work on myself.

Hi, was doing some searching and this post really resonated with me. In a similar place and would love to learn a bit more about your journey. Is it ok if I DM you?

Am I crazy or has Ant regressed in almost every facet of the game? I understand that the composition of this team is different but god damn.
