Barrel Torque Ludicrocity

Just because you are an engineer doesn't mean you are correct. I don't cut prefits for ARC actions anymore. They can't seem to hit their own specifications..... +.004" headspace from their own print is garbage.

Interesting, +0.004" over print dimension is certainly enough to cause an issue with a prefit and I don't blame you for not wanting to do prefits for them anymore... Nobody likes dealing with returns and reworks when it could have been avoided.

I'm sure you've measured a much larger sample size of ARC actions than I have, but between 9 ARC actions of 3 different models that share an identical tenon print that I've measured, they've all measured well within the print tolerance, and all 9 actions measured within a total span of 0.0012" even when swapping bolt heads around between all the actions.

The 9 I've measured were certainly good enough for prefits but like any chamber job regardless of action brand, if you want to hit an exact headspace dimension you either need the action in hand or accurate action face to bolt face measurements.

If I'm ordering a custom prefit, even for an action that supposedly guarantees an action face to bolt face dimension within +/- 0.001" according to the manufacturers print, I always provide the smith with a measurement from the action face to the bolt face taken with a calibrated depth mic measured multiple times in multiple spots on the bolt face on my action that the barrel will be going on. Doing this I've yet to find any out of spec dimensional surprises regardless of brand, but I'm sure you've measured many more actions than I have and can note trends and deviations by manufacturer.

If the smith knows what they're doing and I provide that action to bolt face dimension along with a headspace gauge or a couple of pieces of sized brass and tell them "please headspace to this provided gauge/brass +0.001" using this provided action measurement" they can usually hit the desired headspace dimension within a couple of tenths.

Of course, for the best tenon thread fit the smith needs the action in hand, but that's not always convenient if you're still shooting out the current barrel and don't want any down time.

Rifle Scopes Official Zero Compromise Optic News & Updates

They all have the same FOV all around the world, I've read about some saying we use FOV restrictors for certain markets or that we've not opened them up to the full potential etc etc.

I work sales for ZCO HQ in Austria and to the best of my knowledge neither is a thing.
And welcome to the fun! Glad to have your wisdom and voice.

What's the status on these being offered with the larger field of view? I apologize if this has been asked, I went back a few pages and didn't see anything. I haven't looked at optics much since early in the year and remember thats what all the talk was about.

4DOF inclined fire error

I think Hornady (LedZep-Joe) is overcomplicating things with 6DOF, wind modeling, and so on—turning what should be a simple algorithmic error into a convoluted mess. The truth is much simpler: don’t lose sight of the forest for the trees.
When their software was released, one of the first features I tested was Angle Fire, since it’s a key quality indicator in any firing solution. Focusing on wind profiles, range winds, and slope corrections will only distract them from the real issue.
IMHO, it’s surprising that no one else—including Hornady—has noticed the obvious after all this time. As always, the truth is right in front of you.

FN SCAR IS DEAD; LONG LIVE THE SCAR! US and Belgium Production is over.

I was involved a little in the DOD SCAR experience. Here is what killed the gun.

FN overgassed it badly.

The gas regulation is poorly thought out.

Leadership didn't give troops the training time to overcome the reciprocating charging handle.

The handguard design and length is from 2001, which exacerbated the charging handle issue.

The mags were ungodly expensive. They shouldn't be. D&H makes the mags.

It is 3000 dollars. The price they were selling for, post sample to dealers at Shot when they first came out, was 900 dollars. That is what FN should have remembered when selling them.


If you bite the bullet on the mags, put in a 3 select regulator from mototech, and put a KDG extended handguard on, the gun is the BEST shooting large frame 308 ever. It is light, soft shooting, and accurate.

It should have had a minimum of post issue development but everyone wanted to shit on it because it was different. However, it was the best small arms iteration of the last 20 years.
