Unfortunately they're both chambered in 6.8 SPC but whatever.

Why did you spend so much on two ARs?

>>331481

It was a gud price online. I'm gna trade one and keep one. If one was in 5.56 instead of SPC id keep both ;_;

I don't really know much about Barrett or this rifle but it seems to be pretty good.

It's a super expensive piston-AR. It'll work very well, but not much better than a regular AR.

>>331483

What kinda price did you get for them?

>>331497

$1000 buckaroonies each

Anybody know about the 6.8SPC round? is it even worth keeping one of these?

>>331500

That's a fucking fantastic deal. I'd sell those on armslist for at least two grand each.

>>331501

It's an okay round. Unless it's the hotter SPC II load it's no better than modern 5.56 loadings. If you want a very very in-depth look into why, this is a pretty good article.

you're in for a robbery

from me, to you

what is that gray surface treatment they use?

>>331506

what's the difference with SPC II? I've seen it mentioned but never looked in to it

>>331512

>admits plan to steal from me

>thinks im still going to answer his questions

fuck off man

>flyweight

Are you going to take them into orbit and need to shave off every ounce?

>>331506

>believing Nathaniel's biased bullshit

>>331501

Most likely they'll be 6.8 SPC II, which is a pretty good round, better than 5.56(IMO) but not a lot of support for it.

As much as I hate to admit it, 6.5 Grendel is a much better round than both.

>>331632

sounds like i should sell both of them

>>331674

Sell both for $2000, then if you still want a REC7, get a REC7DI chambered in .300 BLK

>>331635

>fuck piston ARs tho tbh smh etc

>posts the bolt carrier from the IV8888 meltdown video

Yea, because the average piston AR15 is going to have 850 rounds of near continuous full auto fire put through it on a regular basis…

The only reason why that carrier strike face got like that is because of the piston getting bent, and the reason why the piston bent was because it got so hot from the sustained full auto fire.

Is it just me, or is there a recent uptake in the number of people spending large sums of money on weapons without the benefit of knowing the first thing about what it is they're buying?

Must be nice to have more money than sense.

>what's the difference with SPC II?

Runs at a higher pressure than the original spec.

>>331632

>biased bullshit

The article is literally just an explanation of why the cartridge was adopted and some data. I'm sorry he clowned on your silly little special snowflake cartridge.

>6.5 Grendel is a much better round than both.

That's silly. They're two different cartridges with two different case capacities, projectiles, and purposes. One is an intermediate cartridge and the other straddles the line between an intermediate and a full-sized cartridge.

But certainly if you're going to get a special snowflake cartridge you should at least get something that has differences in performance and purpose from 5.56 like .300BLK or 6.5 Grendel.

Every election season this hilarious shit rolls around. I make it a game by going to gunshows with a friend and doing a Price is Right bidding game over the most expensive Surefire 100-rounder.

>This is almost exactly what I get but use 30 grains of AA2200 with SSA brass and CCI 41, under the 95 TTSX at 2.285" OAL. My 12.5" barrel throws them at ~2730 FPS. T

http://68forums.com/forums/showthread.php?55729-95gr-TTSX-and-120gr-SST-velocities-from-12-5-quot-6-8

A 95 grain bullet from a 12.5 sbr going 2730fps. That's why I want a 6.8 spc.

While the 6.5 grendel may be better long distance I think there is still more development to do, something in between 6.5gren and 7.62rfn has to be both available and good food for ar15s.

>>331706

you got me heh. but unfortunately that piston design will do that peening after enough normal operation, I guarantee it. the bent piston rod may be striking high, but if that was the only issue the edge would be fucked and the lower end wouldn't be deformed. the Barret carrier is made of 8620 steel, which the LMT most likely is also.

sexy

They already have the cases ready, they can start production with a minor modification of the projectile tooling.

>was adopted

But it wasn't adopted, you'd knew that if you actually read the damn thing and I've already admitted the 6.5 is better all around.

>For these reasons, when examining the ballistics of both the Mk. 262 round and 6.8mm SPC, I will be using non-calculated, non-empirical velocity figures based on the common performance of the two rounds.

>To make an accurate ballistic comparison between the 5.56mm and 6.8mm rounds, we will use JBM Ballistic’s excellent external ballistics calculator.

>Is 60KPSI 6.8 SPC safe? Yes, probably, if you are just shooting at the range. However, it's unrealistic for military ammunition (which is the subject of this article).

Since OP most likely won't run 20-40000 rounds of "military ammunition" through his rifle, and he'll probably be shooting off the shelf or hand loads: and that being the case, Nathaniel's hit piece on 6.8 is of no relevance to this thread.

>>331635

Most combat occurs within 25 meters, so drift doesn't matter.

BTW OP, if you're going to sell them, wait until November/October election panic then sell them for 3 times what you bought them for.

>>332238

This. Maybe see about traveling to states where a ban seems likely.
