Here's some history on what you have in your hands... This is a nice gun. http://www.smallarmsreview.com/display.article.cfm?idarticles=2649

If you have a 7.000" internal-depth extension on a .308AR, then you need to be running a 2.500" long buffer. That's a straight up AR15 recoil system on that gun, probably with spring, too, so just shiit-can the whole thing. The buffer bumper on the end of that buffer has had the shiit beat out of it, by the looks of it. Dump it all.

I see two HUGE issues right here, fighting each other. First, that receiver extension is garbage. For an AR15, it should have an internal depth of 7.000", not 6 3/4" - that receiver extension is WAY outta spec. Second. 3.250" buffer. That's a great buffer length if you're running an Armalite AR-10 Carbine Recoil System... which has a receiver extension depth of 7 5/8". That buffer is long enough to run on one of those. But it's not gonna run in a .308AR with a 7.000" extension - much less a shorter one, that's not to spec. That recoil system is garbage, and it's the primary source of your problems. Shiit-can it. Dumpster Fire wouldn't be agood enough send-off for that thing. Buy the Armalite AR-10 Carbine Recoil System, install it, and let's start there. I'll be you have no more gun issues. Not with the parts that you've listed, and that gas tube pic - that gas tube is perfect length. Ranier makes good barrels, too. You need this, and you'll be laying out about $65 for all of this: https://www.armalite.com/product/ar10rekit01-6-position-receiver-extension-kit/ Shows out of stock right now, but CALL Armalite on the phone and see if theey can piece a kit together for you and send it to you. Trust me on that. Their number is: Phone LOCAL: 623-780-1050 TOLL FREE: 800-336-0184 Hours of Operation: M-F 7am – 4pm MST

Nope, not at all, with most modern quality scopes. It really helps when you're stretching that .308 out, though. There are scopes that won't dial all the way for 1000 yards, but a 10MOA or 20MOA setup get's them there. I have 10MOA scope mounts on the ones I use at distance, and a 20MOA setup on the short Grendel. That 20MOA that you have isn't a hindrance at all, and with it built in to the upper, that's a bonus. I wouldn't get rid of that upper setup - that's some quality stuff, and it might be worth searching out that lower, just to make it happen.

K-Bay? Did a 3-week TDY to Hawaii in 1995, then again in 2000, but was never stationed there for a tour. I think 3 weeks was perfect for what I wanted to see, but I don't know if I could take living there for a few years... Welcome aboard.

Damn, I was in Tacoma from 1992~2004 - and got the hell out of there when things started really going downhill in the state. It bums me out, bad, too. I loved it there, but I could never live there again.

RIGHT?!!? I was actually looking a cement trucks, too! I don't care if they don't DRIVE. I don't need the thing to MOVE, just tumble brass!!!

How far do you plan on shooting this rifle? That 20MOA can be very, very handy...

Why don't you start by answering this part... that you avoided...

REALLY? Who has been the Jackass throughout this thread?... I think you need to start reading it again, from your very first post... If you want to start slinging the personal insults, I'm good with that. Once I start, I won't let up on you. Know that now.

Small tits are fun, too...

No need to Sir me - I'm just a regular guy like you and everybody else. I'm lucky enough to have two ex-wives that I don't have to pay for - and FREEDOM now from all their bullshiit. Also lucky for the Freedom of space and land nearby, that I can do anything I want on. Freedom to do what I like to do. I'm lucky, and I take advantage of it, and I try to pass on everything that I have to learn the hard way, so others don't have to learn it so hard...

Every rookie season for someone in the MLB, they say that, right? They dream it. How many of them actually really do it? It's few and far between. I think you're worrying about things that you don't need to worry about, for right now. Hell, you don't even have it, so how do you know how you want it to shoot - before you've even shot it? How are YOU going to react when you shoot it? That's an unknown, right now. You might build something that takes you years to learn how to shoot well. It happens. I can tell you right now, for sure, it takes years of shooting and training to lay down behind a new gun, and shoot that thing at 1k yards - and not be far off. Years of shooting and training to know what to do to make that second round even closer, or eventually hit, with a new gun. That's a different world altogether, yet we build guns with that as the primary goal. They don't always do what we plan, or think they're gonna do, once we pull that trigger. You have to know THAT bit of data first, though, before you can move forward with your plan...

You're gonna have to make a telephone call to Christiensen about that one. Nobody here is gonna know, from experience. Never been posted, if anyone has one. Call them on the phone... Might be completely proprietary.

The details are key in that one... Does not include barrel, gas tube, gas block, muzzle brake, bolt carrier group, charging handle or magazine.

That's a fancy comp - take it off. Completely off. Shoot the rifle with a bare barrel - see what happens. That's either gonna point directly TO or eliminate that comp as a problem here. Remove it and shoot the gun. If that's really the length of your buffer, then it's too long, and that IS causing you some cycling problems. Make sure your measurement is right, with that 5 5/16". That's an issue (the issue), if that's it. You need to be running a buffer that's 5.200" long. Period. Rifle receiver extension is 9 11/16" internal depth, too - measure that, to see if they did something funky here. In the past, they've made carbine extensions that are suposed to be 7.000" internal depth - they've made them 7.100" internal depth, and that screwed with the function of one of my builds before I figured it all out.

You just nailed it,with that statement alone. Don't over-think it. Build with smart parts selection. Once you have a running gun - you look at what it's doing, what you want it to do, and figure out how to change it to meet what you want it to do. You NEED it to cycle, every single time, within what it was designed to do. No matter what the ammo is...

It was after this during the trip, when the Count Basie went off, and this came on... ...that everything went south...

The difference here, is how you started this thread, and your giant boner that you have for race-gun parts, that you propagated throughout this thread. NOW,you're saying that your only goal is shooting 100 yards... Below, also in red, are your first few posts here, on what you needed. NEEDED. You insinuated that you already know the appropriate twist for shooting steel at 700-1000 yards - and you were not correct, because you don't know what projectiles you should be shooting, if 700-1000 yards is really a goal that you have - which it is not. Apparently. Keep in mind, I'm not making this up here - these were the first two posts that you made here. I didn't make them - YOU made them. Go back and read them, if you don't remember what you wrote. You were given some very solid recommendations - and then you went off the rails on race-gun parts, as well as quoting whatever "theoretically" that you learned on the inter-webz. Pure bullshiit. Whatever. Then, you get into youre race-gun parts argument: After all this bullshiit that you went through here, and your arguments on race-gun parts - that YOU don't even know WTF you're talking about... You buy a BCA barrel, and COMPLETELY change the direction of the topic that YOU started. Now, you're building a mythical $400 gun. You are some piece of work. What trigger time do you actually have? How much have you actually shot? I was nice in my replies throughout this thread with you, and your bullshiit, but those days are done. As far as guns go, you couldn't find your ass with both hands AND a map to it. You need to get over this "research" bullshiit, and what you think you've found as great info - and get a gun and shoot it. Then, after a hundred rounds, when you finally zero it - start to shoot it at 200 yards and see what happens. You're a long ways away from shooting and hitting anything at 700-1000 yards, like your original claim that you made for this gun - you'll not hit shiit at that distance, not where you are now. From what you're stating, and all your research, you're gonna need targets at 25 and 50, just to get something to a 100-yard zero. You, as I stated before, are just an Ask-Hole. Ask everything, then don't apply any results that you are given. Because, you research. Get a gun, and just shoot it. It's gonna become pretty clear once you do that. If you would have listened to the singe-most important piece of information that you were given in this thread, right at Post #2, you would have bought that Fulton Armory barrel. That's all out the window now, because you only want to shoot 100 yards, and all your original FLUFF was just that. Bullshiit, from you.

There are no $400 builds. Prove me wrong.

Are you talking about going straight to a 10oz buffer, right away? "Dimishing returns" in that regard? One big one would be -the gun doesn't function, because the gas system isn't up to par. That's one fast way to find out, though. You'll know before the first mag is gone.

Why you laughing - you went across country with him. Twice...

Yes, it will.

I'm not happy with you right now. I should be on Amazon looking for toilet paper, but I'm on Harbor Freight looking for small concrete mixers...

You fucker -after posting that, you have me wanting a fucking concrete mixer for a damn brass tumbler. I damn sure don't NEED it, but now I want to try it, and see if it's even worth a shiit. Fuk, man.
