Looks good - WAY better than being too short on the gas tube.

He built it himself... Just like his other cannon, firing the giant arrowhead... He's got some serious shiit on his YT channel...

Success, brother!!! (That was a dirty girl... Kinda excites me, those dirty girls... )

WTF. That first post is full of all kinds of stuff, but I'm not going to get into it tonight. In the meantime @dafish, go post an intro and tell us more about yourself. This one right here: How many rifles do you own, and how accurate are you with them? Is this your first semi-auto AR platform? This isn't a slam - these are serious questions, and not something to "be inferred" as "being attacked." If somehow, I've hurt your feelings, and you feel that way, and you're offended - then get over those hurt feelings. We need to be men and deal with life, as it presents us. Please hit the intro section and tell us about yourself, and please answer my questions honestly. That's the only way to go forward from here.

So, you have a minimum buffer weight - something that's "enough ass to control the mass - and pressure." How is it that DPMS did what THEY did on the LR-308? They used an AR15 receiver extension that was 7.000" internal depth (they had them on the shelves, right?}. They redesigned the buffer to work with a 7.000" internal depth collapsible extension (AR15 part), and came up with a 2.500" long buffer. Even if you stuff an aluminum-bodied buffer with TWO tungsten weights, it only weighs 3.8oz. You can't make an aluminum bodied buffer that's 2.500" long WORK in a collapsible extension on a .308AR, and make it any heavier than 3.8oz, even spending your money on those two (only two fit) tungsten weights... DPMS redesigned the spring. They made it stiffer, in order to compensate. No other manufacturer does this. There are a shiit-ton of places that sell "Armalite AR-10 springs" and "DPMS LR-308" springs... and don't have a clue. Not one CLUE. They just rebadge their AR15 springs. And that don't cut it. Everyone says, "The barrel, trigger and BCG are the heart of your accuracy..." I won't argue that. The recoil system and the gas system are the HEART of your reliability - and you MUST balance those two systems. If you don't, your gun might be accurate - but it runs like shiit. 3.8oz buffers in a .308AR is not where you want to be. Even if you get the perfect spring - you just compromised on the design of the system, from the very designer, Eugene Stoner. You're making all kinds of other changes to make that gun run. So far, I haven't seen anyone smarter than Eugene Stoner show up with anything else that's as reliable, in operation. When you start "balancing compromises," which is both compromises in money and function, you compromised your reliability. One perfect example I have is a specific manufacturer that likes to make cheap .308ARs, affordable to everyone, and with a "lifetime guarantee." They ship with a gas port too small, and a gas tube that's too short - and they compensate for this with a recoil system that's too weak for the .308AR, .308Win round... So, how does it work? Typical complaints are, "It's over gassed, and I added an adjustable gas block to fix it..." Yeah, so... How's it "over gassed" when the gas port is too small? How's it over gassed when the gas tube is too short? OH! They used a recoil system toss-up with a buffer weight that was detemined "adequate" for the full-auto M4A1 5.56 rifle, some unknown spring, in a buffer that's 2.500" long, inside an AR15 Carbine receiver extension... It's not "over gassed" in the least, and you DO NOT need an adjustable gas block to "tame that beast" at all. You're under-recoiled from the get go, because that was CHEAPER to do on the assembly line, and other compromises were made in the barrel production, the serious compromise with gas port location on the barrel in order to use the cheaper - everywhere - AR15 gas tubes. "Well, the gun SHOULD work most of the time, for most of the people, with most ammo... " Not good enough... Off my

There's money involved around tungsten - alot of money. You guys realize that when you pay for heavier buffers. The more tungsten you buy (H1, H2,H3) the more you pay for it. Go buy a VLTOR H6 buffer... You'll quickly see what I mean - 4 tungsten weights... So, on a gun (Armalite AR-10) that was designed for a 5.4oz buffer, that was 5.200" long, running inside a receiver extension that was9 11/16" internal depth, ... THAT was it's design, for proper operation. Done deal. Period. Armalite made a collapsible stock, and had to figure this out - they already knew that the buffer weight had to be 5.4oz, but the buffer had to be shorter, and so did the receiver extension. Eugene Stoner developed a 7 5/8" internal depth receiver, because, BECAUSE, he changed the buffer to tungsten weights instead of steel, and got the buffer length down to 3.250" with those tungsten weights. And the fucker weighed 5.4oz. He made his design parameters WORK, based off the weight of the buffer that's required to run the AR-10 (the ONLY one running then...). So, in short, the .308AR platform was already decided, WAY BEFORE US, and the minimum buffer weight needed was 5.4oz, and that was based on the rifle config. Part 3 coming up.

This piqued my interest - this statement right here, and got me thinking. I had the M4A1 since it's introduction. My first was #W318708. That was the number of the gun on my weapons card, and the same one I had for 10 years. They had standard 3.250" AR15 carbine buffers in them, 3.0oz. Not long after I got that gun, there was a "reliability improvement program" with them, and we had to send them all in to the "Depot Level Maintenance," which was our own armorers in that unit. Some notification came down, guns were changed, and we hadn't even drawn them from the arms room to make that happen- our Armorer's made it happen. Curious enough, those guys were right down the hallway from me, so I went in there to ask them what all the shiit was about. "Ah, we put some new heavier buffer in there had to take your buffer apart and take out a steel weight and put in a tungsten weight - one tungsten and two steel, over the three steel weights, and we gave all you guys a new buffer spring..." Fucking H1 buffer, at 3.8oz. That was "necessary" to control the auto-fire in the 14.5" carbine-gas barrels, on the M4A1 - heavier buffer, new spring (stock spring). We went from a 3.0oz standard buffer to a 3.8oz "H1" buffer - and they weren't marked - the unit armorers upgraded them with a tungsten weight in place of a steel weight... Now,that made the M4A1 more reliable,in 5.56, in full auto. How in the hell does that somehow come around to being "the ideal buffer weight" in a.308AR platform? Short answer is, it's NOT. H1 buffer in a .308AR, that's designed for a 5.4oz buffer?! Gotta be kidding me... The .308AR platform was designed around a 5.4oz buffer, FIRST, in order to control the weight, mass and force of the BCG firing a .308 Win round through this platform. Period. Part 2 coming up...

Keep in mind - if that gas port is too small - and I'm betting it's 0.070" gas port diameter, and too small - then an adjustable gas block won't do a thing for you. It'll never let more gas through than that gas port diameter will, it will only restrict available gas DOWN... You need to have a gas port diameter of 0.080~0.085" to run an 18" midlength-gas setup. If you're gonna do the adjustable gas block anyway, just drill the gas port to 0.085" right away and be done with experimenting. Dial the adjustable gas block down from there, if you want, but you probably won't have to. Another thing - the only way to test an adjustable gas block is to run the thing Wide Open after you install it. If you run it Wide Open, and it's still not enough gas to lock the bolt back on a single round in a magazine - then the gas port is still too small. <<< That would be on an operational gun... You are on brand new hardware here... Get rounds out of your gun before you start paying with the adjustable gas block. This takes carbon-fouling, to seal a couple of areas - you must have a seal around the gas block-to-the-barrel. You must have a seal aaround the gas tube-to-the-gas block. Sometimes this might take 100~200 rounds. The actual carbon-fouling-sealing happens alot faster than that, at a lower round count, but the whole bigass AR-gun needs broken in. This is a good time to follow any barrel break-in procedures that you like, as well. Shoot 5, clean the barrel, whatever you like to follow.

Call Armalite - on the phone. You will speak to a human. It's OOS at DSG Arms right now, or I'd direct you there. Talk to someone at Armalite, and I'll bet they ship you one.

It didn't meet the requirements, and it wasn't even submitted into the call from the Army - and that's Kriss's call. It wasn't even in there. And if they wanted to show that it: ...then they would have debuted the initial configuration in 10mm... You find that comparison article yet?... You had to get this information somewhere, and I'd love to read that article... Lemme know when you find it.

How did the Kriss do in the Army tests? Got any info on that? Here's something on the B&T: Any info on that Kriss vs. B&T information yet, that you referenced earlier?...

You are fast like rabbit, my brother. Astounding...

@Robocop1051 this is another one of the recent ones that could move to the new section - this is good stuff...

Lesson 65b. You snooze, you lose.

WHAT HE SAID, ALREADY!!!!

And he wakes up with a GIANT BONER!!!...

Genghis Khan is my hero.

That's what I was thinking, too... That's a nice one, bubba!

That was the Kimber Ultra RCP II, that little 3" barreled .45. Rob already made a comment that he loved it, and at the end of the shoot it was no where to be found. After "discovery and recovery", it smelled like balls, so I knew where he was hiding it...

Also - whach for primers that were set too deep - that's gonna cause a light primer strike, or no primer strike. Hard to do to the 5.56 case, but it can be done, brother.

I did, when it came out, and for years now - I know about it... I never could find a comparison article on the Kriss vs. the B&T - can you link that so we can all read it?...

This needs to be fully lit up on Full30, if it hasn't been done already brother.

In, for these guys. That should be 63 pieces at a quarter, ans $20.10 on the 30 Carbine. $45 cover it all, shipped? You already know you're in my Favorites on PP, and I send you anniversary and kid-b-day gifts all the time...

Quoting an article from Moriarty Arms from 3 years ago doesn't help, either. I don't think the PSA Gen 2 was out then, and the PSA first-gen was a train wreck of bad specs. The bottom line is simple - you've chosen the 80% route for a lower, based on a self-proclaimed proprietary upper. What you should do is stick with the 80% lower, if that's your definite path - but use a known upper receiver, instead of going after lowest-priced upper receiver. You have to choose what you do here - not us. I'm not the one spending your money. If I was, I wouldn't care - because it's not my money. You're in a tough spot with your chosen parts, and there's no supporting documentation to go from here...

That's complete bullshiit, and you know it. The VERY FIRST TIME I met you, you asked, "What are you carrying?..." I had a 4" Kimber 1911 Tac Pro II and 44 rounds of .45 ACP on me. And I showed you... You kind laughed, and started stripping yourself - and you pulled about 17 guns off your body, fucker...
