ARs IN 6.8mm REMINGTON SPC

[Edsel]

What make / models would you recommend?

Presently have a 20” LWRCi R.E.P.R. in .308 Winchester which is grossly inaccurate for the money I paid.

Would’ve liked the SIX-8 A5 because it does look kewl, if not for anticipating the same issues above (“You don’t get it - it’s built as a 4 MOA combat rifle!”).

I’m not even sure which ones use proper 6.8mm SPC magazines.

I have a 6.8SPC upper from WOA that shoots very nicely

Yes it is

Go to 6.8 .com and there is a lot of info there. Arp is kind of the go to barrel people for 6.8. I have several and they shoot great

I built my 6.8 with a 12” ARP barrel. I believe they have sold out to another company and I have no experience with their new barrels. My barrels shoots fantastic!

 

[Hecouldgoalltheway]

I wouldn't go beyond 16" with the barrel. Do your own research, but that extra 2" will get you almost nothing. I've had a few, traded off a barret rec-7 to a member here, just didnt want it sitting unused in the closet.

Curious what you're going to use it for? It is spectacular on eastern whitetail, and I'm told it kills pigs just as well.

To be honest, no true intended purpose.

Can’t think of anything beyond paper - punching with a new caliber.

Just want something new that shoots well, I guess - and this one tickled my fancy.

I have an older LWRC M6A1 in 6.8 SPC. It has a 14.7" clipped and pinned barrel.

Runs like a Singer sewing machine

Are the groups satisfactory, though?

That’s one of my hang - ups with LWRCi.

They are 1-1.5 MOA (5 shots). I changed out the trigger to a Geissele SSA-E and it helped. Finding accurate factory ammo is difficult. I think hand loads would produce better results.

Blackstone will build you an upper using an ARP barrel. https://www.blackstonearms.com/category-s/100.htm

The LWRC Six8 uses a proprietary pmag. While LWRC makes good gear, I'd stay away due to that and the costs.

Yes..the old M6 that I have does not use a proprietary magazine

Same barrels as H made.

Yeah, the barret I had shot some of the hornady loads sub moa, but the other 3 or 4 barrels I had shot 1.5-2.5moa with factory ammo. I loaded up some 95gr TNT's to shoot coyotes with and got a really accurate load in a few barrels. You can imagine what that bullet does to a coyote..

 

[Hecouldgoalltheway]

I have killed a handful of whitetail with the 120gr sst bullets. You couldn't ask for better performance. My shots were all under 100y, but I'd consider it 400y capable on whitetail or the like.

 

[346ci]

I use the 120gr SSTs out of a 12.5" for deer. This might be my 15th year using that combo and haven't found anything to replace it yet.

 

[Baron85]

I have been running 90gr TNT and has done good on coyotes but shot some pigs and white tail and wasn’t impressed. Switched to 115 federal fusion and works great. I just placed an order for some 105 cavity back bullets since I’m running low on the 115’s

 

[The Knuckle]

LWRC uppers and lowers are nicely designed. I would bet the accuracy issues with the 308 are probably from it being a piston vs DI. The lwrc barrels free float very well but you are locked into their handguard. and a completely ambi lower is nice too.

 

[diggler1833]

120s out of the 6.8, or 123s out of the Grendel, the SST is a fantastic performer on game.

Also had good luck with the 105 Cavity Back, 100 Accubond, and 95gr TTSX out of the 6.8.

I'm still running an 18" Ambush Arms (DD) rifle. It's now retired from thermal pig hunting, and is set up for close range daytime deer.

I first saw this rifle on an online review by who I think was Dick Metcalf (?).

It was unusual in that the rifle also had a Trijicon TARS on it.

Couldn't find it online anymore.

EDIT: It was on Guns & Ammo, with the article's title being "Most Refined Battle Rifle? LWRCI REPR Review." It was indeed written by Dick Metcalf.

This was from the time when the R.E.P.R. gas ports still had an "off" setting (mine only has "normal" and "suppressed").

That review might have been where this image came from, originally.

 

[Edsel]

This is so weird.

I simply cannot find that review of the LWRCi REPR with Dick Metcalf anywhere.

As a matter of fact, reverse - searching using images have come up blank.

It's almost like his entire online presence was purged.

 

[Edsel]

I do wonder why this caliber hasn't become as popular (as it should have been?).

 

[Baron85]

I agree, it’s a bummer it didn’t take off. I think it all comes down to marketing, hype, and the name. Oh and the fact that it was neutered by the spec 1 and 2 chamber so factory ammo has to be de tuned to work in all guns.

 

[Baron85]

I still love it though and just received delivery of 250 more brass and 100 cavity back 105’s to try out

 

[hlee]

I think the 6.8 SPC suffered from not being 6.5, in a time when EVERYTHING new was 6.5. And, the 6.8 mm caliber has always had lackluster bullet options. And, that’s from a 270 win slut…

How was it neutered? I never followed it that close but curious

Something about a highly constrained freebore, I think.

They had to “Wylde” it for the 2nd iteration.

I could be wrong.

 

[Baron85]

That is my understanding. Something with the first gen having a short or tight freebore that raised pressure. What ever they did on the 2nd gen allowed higher velocity/pressure. But since both chamber the same ammo the factory ammo has to load to the worst chamber to keep it safe in all guns.

Kinda the same reason you won’t find factory 223 ammo with bullets seated long to allow max performance. Most factory ammo is loaded to allow it to fit in AR mags which neuters it.

@Constructor is the H everyone refers to, FYI. Big 6.8 dude.

 

[XLR308]

It wasn't neutered it was Remingtoned.
Same as the 260 rem it took someone else and actual shooters to fix what they fucked up.

 

[Baron85]

True. If Remington hadn’t goofed the 260 the 6.5cm would have never been developed.

You'll like the 105s.

That guy reached out to me when I was having an issue with my Criterion barrel (gas port size and they weren't helping). He walked me through the easy process of opening up my port myself, and that rifle has been a hammer ever since. FWIW my barrel was accurate...it just had a .068 port for a rifle-length gas on an 18", .308 barrel.

Big fan of the dude.

 

[Edsel]

What the hey.

Well, I personally would not like to have Kalashnikov - curved magazines in an AR platform unless they were rockers.

 

[Edsel]

Damn.

I can’t help but drool over the looks of that (already assumed to be grossly inaccurate) LWRCi.

Buying one will be like welcoming another Kalashnikov, only that there’s no cheap blaster ammunition to take for granted.

Giving in will sink a number of projects!…
