Flash hider torque specs that cause accuracy issues

[granitestater]

When I built a 3 gun rifle, I put on a MD with crush washer and torqued to 25. The rifle would not shoot better than 1.5" groups with a match barrel. Very frustrating and disappointing. 2 years later I put an AFAB with shims on a new rifle and decided to try the shims on the 3 gun rifle. Groups shrank to .5".

A smith vortex will do the same thing without the hassle of getting the correct number of shims. Just screw it on and it self tightens and doesn’t cause accuracy issues.

While the Vortex is a great flash suppressor, you won’t see many on 3 Gun rifles, and it is also not similar to the AFAB.

I didn’t say it was similar. The vortex costs less and is not a compensator. But... I personally don’t see the need for a comp on a .223 rifle and I don’t have the patience to fool with shims or peel washers or whatever. The s itch is quick, easy doesn’t destroy accuracy and almost eliminates muzzle flash.

You quoted a user that was talking about a comp/brake on a gamer gun (if you think brakes are useless, get a shot timer.), and specifically the AFAB.
You didn’t say it was similar. You literally said “a Smith Vortex will do the same thing”.

I like the Vortex also; just pointing out that it is a different tool for different tasks.

I only run A2s unless the rifle has a suppressor. Suppressor mounts typically need torque and if you’ve ever tried to remove a can that’s been shot 700-1000 times without removal you’d know why torque and rocksett are needed.

If you’re torquing a basic FH or comp more than a smidge you’re doing it wrong.

The flip side is if you’re over torquing a suppressor mount that’s wrong too. I’ve messed up both.

It's not a problem with our *big* 5/8-24 threads...

You have 5/8-24 on 5.56 guns? Interesting. Why?

Edit: I mean I know it’s “better” but what made you go with that.

I'm not Clint, but here is the thread dedicated to what he is doing with his barrels. https://www.m4carbine.net/showthread...PTIMUM-Barrels

We consider threads to be an integral part of the overall barrel profile.

1/2-28 threads were a good choice for the lightweight barrel profile of the original M16 and became standard.

Heavier profile barrels were designed but retained the small threads mostly because it was "standard" and worked well enough to secure existing muzzle devices.

Striving for improvement often involves revisiting past design decisions in light of the current landscape of requirements.

Two recent trends helped tip the balance in favor of us making the change to larger threads.

On the commercial side, the popularity of larger caliber AR variants in 6.8SPC and 300BLK has greatly increased the number and availability of 5/8-24 muzzle devices.

On the technical side, the popularity of suppressors has driven the need for a stronger attachment method.

While a 1/2-28 thread is completely sufficient to secure a 2oz flash hider with a crush washer, a 16oz suppressor hanging 8" past the muzzle with a shimmed QD mount is a different matter altogether.

Just as an FYI, some suppressor manufacturers do not make a 5/8x24 muzzle device for their 556 cans. IMO I think you would be way better off doing a taper with 1/2x28 vs eliminating a whole group from buying your barrels because they don't have the proper thread pitch.

He also makes barrels with the traditional threading. IMHO, his offerings are worth the squeeze if they fit your equipment set up.
