First, real quick, the 6.8 is not ideal for long range. The round a has realistic range of 600 yards.

If you want a real long range shooter go with a 6.5 Grendel or 6.5 CSS(see tx4guns group buy thread). I have a gun that needs a barrel waiting on one of those two.

But back to my 6.8

That is a 16" WOA barrel, threaded to 5/8x24(Troy Medieval on the way), YHM lo-pro gas block, mid-legnth gas system, with a set of rifle length YHM ultralight handguards on top a High Standard lower with an off the shelf LPK. Thanx Log for me letting borrow the vice and action block tonight.

I'm sure Deats will correct me if I'm wrong, but I'm pretty sure a 20" barrel isn't necessary on a 6.8 spc. It was designed to be used in short barrels, and I believe a 16" is about all it needs.

Yep, for optimum performance, 10.5"-16" for the 6.8, 18" and up for the 6.5.

Log and NRH are spot on.

To make this AR related...I would have normally been carrying one of my SBR'd AR's or AK's...

Knocked a pig over yesterday evening with one of my CMP Garands. Rolled up on them on my 4 wheeler while making a corn run to one of the feeders, they didn't notice me until I was at about 60 yards. Could have dropped a half a dozen but it was just so cool looking at them over the sights of the Garand as they started running... It was just like that scene in Band of Brothers when the Capt Winters comes over the levy and shoots the young German soldier and just dropped him and then all the others started running...just like that. Pretty cool and very surreal because that was running through my head all at the same time.

When I shot the first one he just went down and the hit was VERY audible. Just put him down. I swung on the others as the whole BofB scene went through my head. I saw this one out of the corner of my eye trying to get up and drag himself off the battlefield, so he got one in the head. Same sort of reaction, just flattened him.

I was shooting Greek surplus M2 ball, and I am very impressed with its performance. Even though I hit him too far back (it was off-hand at 60 yards and he was running) the exit wound was about 6 inches long and had at least three organs hanging out. I can see why the M1 was so loved by combat vets, that M2 ball hits very hard and the rifle was very flat, quick follow ups would have been very easy.

Next time I will be shooting until I hear the Ping.





Sorry for the crappy cell phone pic.

Edit to add: I think I need a bayonet now...

There was a whole mess of them off I-45 on Sunday. If only it wasn't illegal to hunt from the interstate I'd have pulled my AR out of the back and let loose a little fury!

So...

I bought a particular accessory off AIM Surplus but they are nearly two weeks behind on processing and shipping. They were shipping orders placed on April 6 today (4/15). So the way I figure, at worst my stuff should ship at the latest 4/21 (a 4/9 order).

However, Brownells has the same accessory in stock and I know they're not having any processing problems (ordered a handguard removal tool from them and it took approx. a week from order to delivered) so if I were in a real hurry I know I could order from Brownells and probably get it in pretty quick.

Should I cancel my AIM order or just be patient and stick with what I've got? Pricing is approx. the same on both web sites so I'm not worried about that. I'm just worried about what time frame I'm looking at for delivery since I won't be here much longer.


That being said, I also ordered a particular device from LaRue. Word is they're shipping these in batches and the last batch went out about mid-March. Ordered this device on 4/9. Hopefully they're about to send out the next batch because if that gets any later I'm going to have to move the shipping date (can't get this device anywhere but LaRue I think).

Also thought I'd throw out there that my set of foliage green XTM covers came in today. Now if only I had something to put them on...

you cant wait a week?


some of us have been waiting months for parts.


EDIT: i reread. i guess you are moving. Just have them forward to new address.

[This message has been edited by 35chililights (edited 4/16/2009 8:43a).]

Get it from Brownells. Thats the beauty of the Freemarket, the customer is in charge. I sure am gonna miss it...

Get your device and be happy. And thanks to CMH and Mouth98 for letting us know we can only speak of "devices" now in public forums.

Remember, loose lips sink your Freedoms! (Well, who wants to be Free in a DHS holding facility?)

I kind of do it as a joke, like the whole "What guns?" thing.

It's a Daniel Defense Omega Rail 7.0. I ordered a FUG from LaRue and I have some foliage green XTM Magpul rail covers to complete the kit. I'm excited to get the stuff all put on.

ETA: Good news, AIM says they're shipping stuff ordered from April 8-9. So that should work out pretty good. Still a little worried about the LaRue order though. I think I'll just holler and have them change the shipping address if it gets too close to moving day.

Re the 6.8SPC; as it was designed to function thru an AR, not so sure a short barrel was a design target. Burning maybe 15% more powder than a 223, why wouldn't it benefit from a little more barrel length?
The guys over at 68forums (who do tend to load real hot) ran a series of tests, and apples to apples, a 20" barrel picked up 100-125 fps over a 16". Whether it's "needed" is up to the application.
My only current 6.8 is a Rem 700 (22" barrel), so no real world comparison for me just yet (though I have a complete lower that needs an upper!).
I sure think Rem did the original design dirty by using a 1:10 twist (good for the 270W, hardly needed for 110gr and less), and I am hearing many barrels are now twisted at 1:11 or 1:12? And have the roomier chamber (throat)?
Ahh the 6.8...the only rifle cartridge I load for, where two different primer size is needed.

The general standard for velocity gain/loss per inch of barrel is 50 FPS. To go from 16 inches to 20 and only gain 125, and having to hotrod to do that, simply isnt worth it.

You also dont get enough velocity to make any difference when you consider the BC's of the 110 and 115 grain bullets used in the 6.8.

When I cut mine from 16 to 11.5", I lost 75 FPS. Worth it? Yep. At 200 yards or less, nothing it touches will know the difference.

GSS, the SPC II chamber will shoot the hotter milspec ammo. Look for one in a 1:11 twist. Best combo out there.

The 6.5 Grendel uses two primer sizes, too. If you resize 7.62x39 brass, most of it has large pockets. The AA/Lapua brass uses small pockets. Just got 200 virgin AA brass pieces yesterday for my new build.

Puryear: I think the "50fps per inch" general rule is very inaccurate, with so many variables in load data. The velocity gain I mentioned was irrelavant to the "hot" loading, as it was same load/different length only. Your own experience of minimal change in velocity (dropping almost 5" ) is interesting; or you using a fast powder for the 6.8? It seems unusual in data, with applicable powder ranging from LilGun to RL10 (bullet weights considered). I'm assuming internal barrel volume, and of course case volume, plays into when barrel length becomes critical. My best accuracy/speed load has been with Benchmark and RL10 (110gr pills).
Though possible to make a "SPC II" chamber from a standard one, I'll probably leave my 700 alone, and wait till I order a AR upper to utilize the latest combo.
I gotta get some of the 85TSX's to try!

[This message has been edited by GSS (edited 4/17/2009 7:18p).]

Omega rail shipped today so don't have to wait much longer.

Still waiting on the LaRue FUG... oh LaRue...

GSS, thats a standard thats been around for a long time. Obviously there are a lot of variables and loading can effect the gain or loss, but its an average.

I have loaded the 110 grn TSX, but mostly I run Hornady LE TAP.

The 6.8 was designed to function best in short barrels as i understand it. Build your barrel and cut it down, I'm curious to see what your numbers are.

hey yall i need advice/help

i have a stripped lower and now have the green light to build.



this is going to be a long list but i want input before i make my decision. pardon any ranting

has anybody used the vltor emod stock. i like the features but havnt sen many reviews


do i want a 1:9 or 1:7 i like the heavier bullets but i like versatility. impact/ stopping power wise is the extra 7 grains from a 55-62 that much in the grand scheme. but i can appreciate the difference between a 55 and 75 grain bullet


i want the flip up back up iron sights .for the front sight should it be pinned? my concern is the threaded screws could back out or come lose. is that unheard off? does anybody use the trijicon night nights, i like the idea just dont know if it is useful, especially if i decide to get a night vision device in the future


optics... im looking at the Leupold vx3 1.5-5 or the Leupold cq/t. can you use your flip sights through a 1.5 power scope? or is that to much magnification. where i getting mine at there is only a $160 difference so cost is not a factor.

i think ive decided on chrome lined barrel and a single stage trigger. and found 5 magpul pmags w window.

man yall i really appreciate the time yall take to answer parts or whole questions like this

Never seen a negative review on it, solid stock. Only common complaint is that facial hair gets caught in the gaps. If you don't shave every morning consider a LMT sopmod.

1:7 will usually do fine with 55 and shines above 62, go with the 1:7 for versatility.

pinned is recommended. a tritium front sight is useful, tritium rears are worse than standard rears because your eye cant focus on the front sight.

you can't use flip ups through a scope with magnification.

I don't have the EMOD, but I've got the older clubfoot. It is solid, and I like it.


Go 1:7 and chrome lined.

Pinned is preferable. If you are going to use set screws, you will want a dimpled area on the barrel for the set screws and to set them with Blue (minimum) or Red (preferred, high heat required to remove) loctite.

Flip up BUIS are intended to be used with non-magnified optics and rifles with quick-detach magnified optics. If you go with either of those scopes, I would go with appropriate Larue mount for them, since they remove in an instant and guarantee a return to zero.

You more than likely wouldn't be able to flip up your rear iron sight with either of those setups anyhow.

I agree with the other answers above, however...

For your use I would not get too worried about twist. If you can find one or the other easier, then fine. Personally I think you would be happier with a 1-9.

My 1-9's all shoot 75's and 77's into an inch or so at 100. But they are better with lighter bullets. And I bet you will shoot a lot more 55's and 62's than anything else. This weekend I was hitting 600 yard steel with Hornady steel case 75's out of a 14.5" 1-9 twist barrel, so your not giving anything up with that twist.

Further, if you do shoot the heavies, it will likely be at pigs and stuff at 100 yards or less so benchrest accuracy really wont be all that important.

And yes, 62's do hit harder than 55's.

Oh, and I wouldnt worry about having screws on your front sight. Dimples are fine if you have them.

The front sight on my 3 Gun rifle uses set screws with no dimples. Almost 5000 rounds and its still there.

Red Loc-tite = Forever.

For you boys who shoot 6.8, please let me know if the following setup is worth $1,100:

EA lower (specifically marked 6.8)
Stag flat top upper
Both are new and unfired
One Mag
Bushnell 4x12 mounted on flat top scope riser

I know log has a 6.8. Where do you find brass for under $1/rnd? Great round, just very expensive. Just want some advice.

price sounds fine...

Brass

SSA silver state armory for 6.8 brass and ammo.

Seems a little high to me...but thats the world we live in.

Whose barrel? Twist and chamber?

What about the bolt and carrier? MPI'd bolt? Check the buffer too. Shoot before you buy if possible.

16". chrome lined. 1-11" twist.

What other specifics do I need to know?

Hmmm... Ord92 inquiring about 6.8; is another group buy in our future?

the downside to that Stag upper is the lack of m4 feed ramps. But you can get those cut in.

M4 feedramps? Is he putting this on a registered full auto lower?

Otherwise they arent needed.

M4 feed ramps on 6.8 not needed?

We will have to disagree.
