Screaming Deals on Armalite Barrels

One thing I would change for the dimensional specs on an 11.5” heavy barrel would be using 5/8x24 threads vs 1/2x28. It’s a big step down in mass when you want the benefits of a heavy barrel that is heat-tolerant, that you are sacrificing extra weight in-favor of better grouping at reasonable distances.

A tight-fit muzzle device and suppressor will mitigate that a bit, but I still don’t like such a dramatic change in barrel profile with the step down to such a small threaded muzzle. It’s just begging to absorb a lot of the heat load and bell out. Chrome-lining and CMV steel help counter that, but any advantage would be good in that area.

For gassing, you can choke the flow of a large port back at the carrier with a Bootleg. Instead of going to heavier buffers, try extra power spring weight in the action spring. I use standard buffers and extra power springs more now, after feeling and seeing how well that manages the cyclic rate.
The whole thing with the 1/2x28 threads on a heavy barrel has always been something that bothered me. I've heard the notion of mitigating this with a muzzle device. What also worries me is overtightening the muzzle device and I dont think I've ever found a definitive torque spec on muzzle devices. If it matters, I always time my muzzle devices with shims.

As for controlling gas, we'll have to agree to disagree regarding using springs to affect closed bolt lock time. Nevertheless, I do agree that controlling gas flow is the way to go. Although I'm trying to get away from using "controls", my chosen method thus far has been riflespeed gas blocks. I think they truly are the best thing going.

Is this a joke?
Can they also shut off the supply of sailboat fuel?
I am not a smart man, but i know what a nuclear sub is.
Must be (LOL). They do refuel nuclear carriers at sea, but it's jet fuel for the aircraft. What "fuel" would a nuke sub need from Norway? My understanding is that they are launched with enough nuclear fuel to last the lifetime of the hull, with diesel only used to run backup generators IF a problem develops with the reactor. The story is highly suspect.

Zelensky is DEFINITELY fucking Starmer up his poopchute. Change my mind. :ROFLMAO:

Z-boy is so butthurt from the old school policeman style talkdown he got from President Trump that he has literally run into the arms of his favorite cuck leftist 'friend' to get petted and comforted. You can't get more pathetic than that.

Also, the 'Democratic senators' that Z had been reported to have 'met with' prior to his meeting with Pres. Trump... Is that even allowed? You lost the election. Meeting another world leader behind the POTUS cabinet's back and manipulating their diplomatic strategy feels like it can carry legal consequences...

Rifle Scopes Another “I want a new scope” thread

So….. Your use should drive the optic. What is your priority? Price, glass quality, turrets, or reticle options for example. Nothing inherently wrong with any of the optics you listed but at the end of the the day it’s YOUR optic.

1st focal plane scopes are really tough for hunting if you grab the wrong reticle, unless it’s illuminated. So now that’s on the table and just drove up the price of the Mark 5…. See where the problem begins?

We can all fanboy our favorite brand for you and in the end you might really hate it because it didn’t fill your needs.

But, you should absolutely buy the T6X with MSR2 reticle because it’s my favorite.

@vh20 less the bipod itself but how I'm loading them and the harris works better for me. Going to test a bit more but explains why I always shoot one gun with a harris better than everything else that uses the Cals.
Mmmm, ok... I've got nothing against the Harris (I have about 4 of them), but the CAL is a more stable platform. That said, there is no way you go from what looks like a 1.5 MOA group to about a <0.2 MOA group just from switching bipods unless something is very wrong with one of them. There is something else at play there. I shoot the CALs better, but the difference is minimal, not huge like that.
