Only way to know is to test it on paper against the clock.

Cut the 18" down to 16" if it's got plenty of life left in it.

Ditto. I've tried some handicap scored shooting sports. Once.

I had the rail milled off a handguard once. Cost like $20 at the machine shop down the road.

Yup, that's where the rubber really hits the road.

One of my favorite parts about the Hide is all the newbies that show up trying to tell seasoned shooters how to convert inches into MOA to call corrections. The entertainment value is next level.

You've already gone way deeper on the numbers than I ever have. I've done a lot of testing with various barrel lengths, gas system lengths, reciprocating weights and spring rates, but I've never put a lot of time into studying graphs or doing any math to understand exactly what's going on. The biggest takeaway from all my tinkering is that the shorter the gas system length the harsher the impulse will be. AGB's help tame a system in any given length, but longer will always end up more docile. Dwell time seems to have some effect on felt recoil. For instance, a carbine gas 16" barrel feels a little more violent (not taking muzzle blast into account) than a carbine gas 12.5" with all other components identical. Same gas system length, very different dwell times. But it doesn't work the other way. A 16" rifle gas may have similar dwell time to a 10.5" carbine gas but that in no way equals a similar recoil impulse.

Apples to Oranges. 6 ARC is for max performance within AR15 mag limitations. 6CM is max performance with an AR10 mag. 6ARC will have longer barrel life, less powder used, lower recoil and fit in the smaller guns. 6CM is better ballistically but has all the drawbacks associated with ballistic performance.

The lower they had pictured is not a standard glock mag receiver. So if the lower is proprietary, and the upper definitely is, there won't be any way to retrofit it into existing guns.

Alright, where is all the fun at?

McGowen and X-Caliber will do 7mm-08. I've got barrels from both companies, very pleased with them.

Same.

Cool to see someone not too far from me on this site.

The owner, @MarkCO used to be pretty active here. Still see him on some 3 gun FB groups on occasion.

Watching with interest..

What's the headstamp on the offending brass?

Wondering also. I see the green one has a thumb rest, but that's all I noticed without really studying them.

Which ones are the fancy ones? I thought it was just three different SKU's, with color being the main differentiating feature.

This is the way.

No. It's just the same 8 guys that crash every shotgun thread that has ever existed.

You're missing the point. Compliance matters above all else.

Say what now?

Just pay more taxes. With a little more money they'll finally get their act together.

There's a few out there, most companies don't list the specs though. All the companies I listed above have them, I think the ADM is called the X Recon or something, JP has two different lengths.

The Odin Zulu probably has the squishiest pad I've seen on an AR stock. RPR take off stocks have some squish too. Just be aware that you probably won't notice the extra cushion on a 223 AR, and that the recoil pad is probably the least meaningful thing you can do to change the way an AR feels.
