Well, I guess by off-duty you are meaning ' in the woods'? Honestly I get where you are coming from in regard to maybe wanting more caliber but for off-duty I look at traveling with it, having it in the trunk for 'what if's' etc. What drives me to stay with 5.56 is frankly the availability of ammo in a variety of austere / semi-austere areas of the country. I have been in Wal-Marts and small stores, bait shops and even convenience stores in some very rural and out of the way areas where you...

I got lucky and found a barely used Spikes Tactical 10.5" MRP barrel on a gear exchange on another AR forum. Unfortunately they are no longer being made. The LMT MRP isn't as popular as it was back in 2008. The aftermarket support really died away. If you can find a used Spikes Tactical, jump on it. Mine has been flawless suppressed.

Just built a 12.5" 6.5 with the new SBA3 brace for personal use. Brace keeps it off paper and limits ATF issues for an off duty rig, 12.5 keeps it handy. If you load, the ELD-X is a monster from what I understand. Currently shooting the factory 130 berger hybrids and liking them. Very limited experience as of yet. Had a shaw barrel cut to my specs to see what I thought before committing to one of the 11.5" Lilja 6.5 barrels but planning to go that route if it pans out.

I can totally appreciate that! The Hill Brothers' videos and posts have me constantly contemplating about updating my 30-30. I have a 1980's Marlin 336 that I would love to chop the barrel to 16" and thread it for a suppressor... but it would still be longer and much heavier than my 9" 300BLK AR. I mainly hunt whitetail in PA, and I'm hoping that next year they finally allow AR's for big game. Last year they allowed semi's for varmint/predator, this year they allowed semi-automatic shotguns...

Agreed re: 5.56. Hard to beat for availability and choices of viable terminal ballistics. That being said, I have a dedicated Kotonics built 6.8 AR that has a Shaw barrel and is boringly reliable, no matter what I feed it. I reload for practice ammo, and the only factory ammo it sees is when I'm confirming zero, or hunting. Speaking of hunting, I've taken about 7 or 8 bucks with it with zero issues (SSA ammo with Sierra Pro Hunter 110 grain bullets).

An AR15 in 6.8 mm makes a great hunting rifle for all lower 48 game out to about 300 yds; hunt with 6.8 mm, practice with 5.56 mm. As for home defensive uses, 5.56 mm has the advantage of optimal penetration depths when using barrier blind ammo; with the right ammo, 6.8 mm also works well in that role--some of the other choices, particularly .300 BLK using TTSX, tend to go a bit too deep for indoor use. I don't think I'd choose 6.5G for critical CQB defensive use.

Uh... No it hasn’t. Unless I missed it manufacturers are still trying to shoehorn a cartridge with a 0.422” rim and 0.402” shoulder into a magazine dimensioned for a cartridge with a 0.378” rim and 0.354” shoulder. This prevents the cartridges from stacking against each other properly. The 6.8SPC is a good enough cartridge in its own right that someone needs to create a magazine wide enough to allow the casings to stack properly and then an AR-15 lower receiver with a wider mag well for that...

Magpul and LWRC made a receiver set and magazines built for 6.8. It is slightly longer and wider than a standard receiver. It was from their Six8 series of rifles. Barrett makes a 6.8 mag but they are a full 30 round magazine, and slightly longer. I don't believe the internal dimensions are different between PRI/Barrett/CPD with the exception of they each use a different style of finishing the magazines which usually leads to CPD having less OAL available due to the overlapping metal and the...

I will say that I would choose a 6.8 rifle for a rifle that isn't going to see thousands of rounds a year, due to the ammo availability and cost in comparison to 5.56. I personally went the 6.8 route in 2014 or so and have been happy with mine. I am confident in the rounds ability to do what I need it to do within 300m or so. The hunting bullet selection is decent with 90grain(TSX, Gold Dot, TNT) all the way through 120-130(SST,TTSX) bullets with 110 grain Vmax and BTHP bullets in the middle...

If I could have only one as a general purpose rifle, I'd go for the 6.8. I've hunted with a number of 6.8 AR's for at least 10 years now, probably longer. I'm no smart guy, but I seem to recall a 16" barrel being the sweet spot for the 6.8. While it and the Grendel are pretty similar to 500yd, I think the Grendel thrives as a long(er) range cartridge and likes long barrels for that purpose. That and the 6.8 has a pretty wide variety of factory loads where the Grendel is much more limited,...

Add another vote for 5.56 here. If you're determined to skip it, though, then 6.5 Grendel gets my vote of the ones you listed. The 120-130gr bullets work well with it, including the new ELD offerings from Hornady. Factory ammo is available (if not as common as 5.56/.223), solid ballistics, and good terminal performance. .224 Valkyrie is also a valid option, but it seems there are still some bugs to work out. I got to check out a prototype JP a while back, and I was impressed with what I saw...

If you reload, 6.8 is not the high mountain that some have tried to make it in terms of availability. I routinely find NOS .277/.270 bullets for sale a number of places, from 90-130 grains although I don't bother loading above 115 grains. It's an easy enough cartridge to reload for, too. To repeat what others have stated, chamber spec is crucial.

Well, I'm pretty high-drag low-speed so take if for what it's worth. They are all capable and probably fairly equal to 200 yards when it comes to blasting deer/paper/people with quality ammo. Limiting it to these three, the Grendel excels at 500-1000 yards with using longer barrels. The Blackout fills the PDW niche especially in the SBR/suppressed config. The 6.8 can be suppressed and can be tweaked to the +500 yard stuff. But given your 16" / 200 yard / kill critter requirements, the 6.8...

Twice now I’ve heard/read here about longer barrels for 6.5G. How long are we talking 20”, 24”? Would 18” be consider long for 6.5G? I ask because my carbine has a nominally 16” barrel but with my BCM comp on it it’s effectively in terms of maneuverability 17”. So 18” to me doesn’t seem like that much of a stretch but would an 18” barrel give the 6.5G enough length to get the most out of the round at longer distances?

I can't give you exact figures off the top of my head, but I went with 20". I wanted the ability (don't know if I'll ever have the opportunity) to shoot to 1000 yds. Some Grendel guys, that are going longer ranges, said 20" was the minimum FOR THAT PURPOSE and 22" or 24" being more popular. Now, there was a sale on the 20" at the time so that was part of it. I also got one of those VG6 (?) brakes with is another 2 or 3" on top of that. As I said, I'm a 6.8 fan; I still feel a little bit...

LIGHTSCOUT, thanks. I would probably never have the opportunity let alone ability to go 1000. There is one place near me that stretches that far but it’s so remote and hard to get to and find that the few guys who use it leave their steel targets permanently set up. I think I’d be good to go with 18” for all of my possible uses.

With those sorts of parameters, I would be inclined to stick with 5.56, with something like Winchester RA556B, Barnes TSX, or maybe Black Hills 77gr OTM, or a combination of all three to make sure you always have what you need. I guess .300BO or 6.8 would also work, but you would have to weigh the pros and cons that have already been discussed in this thread.

For me, if I was to be in CONUS rather than the Nanny State here - my vote would be for 5.56mm (with T1) and maybe another upper in 6.8mm (with a 1-4x variable) if I had the budget later. I keep thinking that when/if I ever get a better (higher paying) job than what I’m doing at the moment (or my forearm project takes off) then I’d seriously look at re-barreling something like a Ruger Scout to 6.8mm.

I find it very comfortable to lug around the woods all day and it performs well at the ranges I need it to for WI deer (10' to 150yds or so).

I get that the OP wants to discuss calibers outside of 5.56mm. I also understand we each need to assess what our personal needs might be. But for my needs, the 5.56mm with the appropriate ammunition can handle my off duty needs as well as it can handle my on duty needs. For me, the largest animal I seriously am in need of defense against would be dogs. I don't hunt as a sport. I live in a region of the Mid-West that consists of hills.
