The standard for the buffer should be 7 5/8" internal depth. You're close enough. That should run a buffer that's 3.250" long, and weigh 5.4 oz. There isn't a buffer for these things made that comes out to 7 3/32" long. Something wasn't measured right to come up with that number.

Not yet. Still haven't had that date set up yet. I'll get to it.

I'm very, very intimately F A M I L I A R with timing muzzle devices. My information still stands - you do NOT tighten and loosen 3 times for a muzzle device. That's for barrel nuts, not muzzle devices. Go research crush washers, peel washers, and timing shims. I bet you put that thing straight on your barrel, and tried to make it line up...

What model of Bushmaster? Need to at least know that part.

Mods/Admins - can we get this moved to the build section? Thanks in advance.

Delta Force’s Head of Iron: A. Greg ‘Ironhead’ Birch by George E. Hand IV Jan 22, 2017 https://sofrep.com/news/delta-forces-head-iron-greg-ironhead-birch/ (Feature Image: Ironhead in the Tora Bora Mountains of Afghanistan hunting UBL) The Delta Force had a head of iron in the day; it had an Ironhead. But it only ever had just the one, the one-and-only Ironhead. Delta Force eventually lost its Ironhead to the 75th Ranger Regiment, the organization from which Ironhead originally came to Delta. It appeared that the Rangers needed an Ironhead just a little bit more than Delta needed one. Delta graciously yielded its Ironhead to the Rangers, a gesture for which they were sorely grateful, those Rangers… after all, who would be anything but immensely grateful at being gifted an Ironhead. “We’ll see your Ironhead, and raise you a dozen of our best men” the Rangers bid. “That’s okay; you take our Ironhead, and you keep the change—God speed!” Delta graciously conceded. Ironhead as he reports to the funeral for the untimely death of our brother Thomas ‘Dalton Fury’ Greer, author of the New York best seller Kill Bin Laden In those days Delta had used the B-Jesus out of its Ironhead. It was late in the year 2001 that Delta sent a squadron of its best warriors to the mountains of Tora Bora Afghanistan, lead by its own Major Thomas “Dalton Fury” Greer as their commander. To ensure sanity of command, and safety of its warriors, Delta released its assault force to the care of its very own Ironhead. Ironhead, Tom Greer and his mauraders It was there, there in ‘Asscrackistan’ that Delta’s Ironhead and the boys smashed the living dog $hit out of a massive force of Al Qaeda in the Tora Bora mountain region, chasing the cowardly Usama Bin Laden from his mountain gauge, across the border into Pakistan. There he remained in hidden exile for the remainder of his wretched life, to be eventually executed by elite Navy SEALs of the exalted SEAL Team Six. Ironhead (right) in the Raq, takes a moment to share a frame with Brian ‘Cracker’ C. It was after the fight in Tora Bora that Delta felt stable enough to pass its sacred torch, its own Ironhead, to the Ranger Regiment. The Ironhead took his Rangers to Iraq to continue the war on terrorism. There, Ironhead lead his Rangers to capture a key strategic target subject, the vaunted Haditha Dam. The Rangers stormed the dam, held by a guard force superior in number to their own… but their’s was never to reason why, and they soundly throttled the Iraqi forces into a rout from their dam haven. The dam was theirs! It belonged to the Ironhead and his Rangers. It was victory… but it was yet a shallow victory, as it had to be owned until a substantial force could arrive to relieve Ironhead’s Rangers, a force that would not arrive for another three days. Ironhead greets our brother and current JSOC Commander, Austin Scott ‘Skipper’ Miller at Tom Greer’s funeral service It was then that the Ironhead and his Rangers did settle in for a sound thrashing from a barrage of over 365, 155mm Iraqi artillery rounds, a barrage that nudged many young Rangers to the brink of collapse of mind and body. Ironhead moved through the continuously artillery pounding to and from fighting positions where his Rangers fought for their lives. He brought them encouragement, orange soda, twizzlers, snacks, and praise. Repeatedly he traversed the dam, all the while under fire, to rally the Ranger spirit, and keep his men in the fight. Haditha Dam, some 316 miles north of Baghdad At the base of the dam an enemy force gathered, edging its way toward the top of the dam to flank the Rangers. The worrier with the head of iron grabbed an SR-25 precision sniper rifle, and laid waste to the advancing fighters below. The enemy forces broke again into a rout, leaving dead and wounded fighters behind. It was then that an unimaginable thing happened. Though head of Iron, there was a heart of gold, one larger even than that of the Grinch who stole Christmas, but you know, after it grew ten sizes normal and broke that bracket thingy. Ironhead descended the steep slope of the rise to the dam. He moved under constant enemy small arms fire from across the water way of the dam. He moved down to where the wounded enemy fighters were, and he pulled them up the slope of the dam to safety, an act for which he was awarded his second Silver Star Tom’s funeral: (L-R) Rodney ‘Stormin’ G. Sheriff of Baghdad John ‘Shrek’ McPhee, Ironhead; all Tom Greer’s Tora Bora mauraders Ironhead continued to rally and coax his troops to stay vigil to the fight, until such time that relief forces arrived to rotate the Rangers off of their hard-won objective. Ironhead left the precious strategically-important Haditha dam with his Rangers, to recover and refit to fight another day. For three days the Iraqi forces had mercilessly hammered the dam, trying so fervently to win it back, and for three days the Iraqis failed; they failed because in their wretched ranks, they had no Ironhead. 75th Regimental Command Sergeant Major A. Greg ‘Ironhead’ Birch, inducted into the Ranger Hall of Fame; no higher honor—respect! In Delta I came to know the Ironhead both in my own squadron, and again in an advance force operations squadron, where I spent my last two years in the unit. In those days the Ironhead had already forged a ironclad reputation for himself as the operator, an operator of the greatest actions and fewest words in the organization. “Hooah” you might get out of him as an indicator of affirmation. If you had made the least bit of sense to him. Otherwise he might not even realize you were talking to him and walk away. At formula 2 high performance driving training The warrior with the head of iron could be seen in the early morning hours before the sun broke the plane of the horizon. He wore combat fatigues, combat boots, a protective ‘gas’ mask, and ran down range for advanced Tarzan training—alone. He wore the mask to restrict his breathing and entice hypoxia—embrace the suck! He wore combat boots because he knew his battlefields would be no place for Nike jogging shoes—who’s your daddy? He always wished it could suck more, the tough muthuh. The unit discouraged running the obstacles courses downrange alone; they were just too dangerous. Ironhead made it a routine practice nonetheless, because in his own words: “The greatest failure is the failure to ask permission to try.” The commander would really, really (no poop, really) NOT like the Ironhead to run downrange, at night, alone, in protective mask… but Ironhead had a head of Iron, a heart of gold, nerves of steel, and legs of spring steel. The Ironhead would not slight his rendition of combat readiness. There was a day I came to work before dawn, just in time to see Ironhead run by clad for combat and with P-Mask on face. I raced to my locker to don all of the same, and set out down range in the night, and at a respectable pace. All I wanted to do was catch up with him close enough that he could see that he had a body there at his six. I managed a catch up without popping my lungs as the Ironhead was vaulting the second or third obstacle. I managed to settle into a cruise speed, albeit at a struggle. I finally saw his masked face turn my way once, then quickly again. At last; he had seen me. Now I could revert to a flailing stupor through the rest of the obstacle course. Our paces matched finally on the long mile stretch back to the compound. I felt my mask slap and press my face tightly with each inhalation, followed by a ballooning attempt to jump off of my face on each exhalation. The Ironhead looked over at me periodically, likely to assess whether I might need first aid before we made it to the end. As we both passed through the end gate, we sputtered to a hands-on-hips-bent-over walk. “No, wait Geo… wait for the Ironhead to take his mask off first!” He finally did so, and then I did. He looked at me and said: “Chik, I knew you’d come.” I looked up from my down, and uttered a single: “Hooah.” Delta had an Ironhead; just one. But there could only ever be just one, you see. The Ironhead doesn’t like his photo taken, he doesn’t like praise, or flattery, or awards. If you suck up to him, he will certainly just turn and walk away. If he approves of you, you might win a simple “hooah;” if he disapproves of you, you will never even see him again. Delta gifted the 75th Ranger Regiment with their one-and-only Ironhead, because he was through with the Delta Force. In the woeful days of the beginning of America’s global war on terrorism, there was a regiment of young men, the very razor’s edge of America’s combat prowess, that needed an Ironhead more. There is no way of truly knowing the extent of Ranger lives Ironhead saved directly and indirectly. Be it by grabbing a ranger by the nape of the neck and the seat of the pants, and throwing him into a cover from shell bursts, or showing up suddenly in the most unholy of artillery barrages with a twizzler, bottle of water, slap on the back, and a deadpan “hooah.” Young men are immortal and indestructible machines that will live forever. So they are, until they come to beg for their mother’s consolation in combat. Young men need old men to show them how to stand when their legs will no longer serve. They long to be shown how, yes, they can advance still when their minds tell them to wither and flee. The young men becomes an old man in combat. The old man becomes a stalwart bastion that holds and tows the line. The young rally behind the bastion, bidding it break… but it never does. “He has an iron will” so it’s been said of certain men, and under certain circumstances, said of a particularly strong and determined individual. I have met a good many of them, and gone so far as to say it even of my self. I patterned myself as best I could after the iron-willed, and intentionally rallied around such men as flag ships. They were who I always looked up to in fervent adoration, for there were none like them. The iron-willed were always the pinnacle of perfection, in my mind. They were who I always longed to mingle with. I dared not ride their coattails, rather extend out my own, lest they shun my company. They were the penultimate… that is, until I met the iron-willed man with a head of iron—the Ironhead! chik sends to Ironhead

Fuckin' Spammer.

Yeah, he NAILED that response... I think this is how he phrased it back to Doc...

Not everything in a fast car is a Mustang. Nor is it a Corvette, or Camaro - especially when you just got your ass kicked by a twin-turbo garage-built Supra... But people come here, and try to find parts for that badass car - without telling us what car they have in the first place. Fuk it, I'll tell them to strap the blow-off valve for the twin-turbo supra RIGHT ONTO that Chevy Volt, and it'll work like a CHAMP! If they're not gonna take the time to know what they're even asking about - then be a dickhead about it. I'll tell them whatever they want to hear. Doesn't mean it's the right information - but they weren't looking for anything else, that day - than what they wanted to hear... Well, ALRIGHTY THEN!!!... AR-10 is Armalite. Only. LR-308 is DPMS, only. LAR-10 is what? You tell me, because it's actually TWO things... But, like sportcars - they're ALL .308ARs. The name of this place wasn't an accident, or after-thought. It was intentional. To capture ALL the 308 AR Platform rifles. Not just the Mustangs, or Camaros, or AR-10s... What's the best aftermarket high-amp starter for my 1998 Mustang engine? You give me an answer, then I tell you I bought it, and it doesn't fit, and I blame you - then tell you that is was a 1998 Camaro, and you gave me the wrong info. Mustang, Camaro - they're both running a 5.0L engine, says both factories... YOU screwed me on the info, you're at fault... Not really, in REAL LAND... But, that's what we face here. Kinda weird, reading about it in car-terms, ain't it. All that shiit is obvious,there, in Car World - but here, in Gun World... Not so much. Dumbasses call Mustangs Camaros and Corvettes - and they're too dumb to know the fucking difference, because that's what the part was labeled as from the seller that sold it to them. ...and we have to decipher all that bullshiit.

Very eloquent description, of the issue-at-hand. I mean that. You knocked that one out of the park. We need to get you into the "loquacious" group. We slam some of them, for being it - but you excelled at it, and need to earn some badges, or merits, or something - all the shiit that we don't offer here. They kill it with the badges, merits, and all that, over on @Full30.com. At any rate, you kicked that one's ass-holio... Ya did well - I mean that. Don't take shiit from weinie-heads that come here and talk shiit - and you didn't. But I usually do that, argumentatively - but you sure did do it pleasantly... I'm not usually that "well with the words," and just speak my mind. It doesn't come out as well as you did it... Don't ever change you, man. Keep doing what you're doing.

TeleStratMan post that a year and a half ago - after he tried to defend "generic terminology" to gun parts. He wasn't happy when we branded "generic guitar parts" into telecasters, stratocasters, and whatever - for guitars. I found a guitar on ebay that was a "stratocaster" - an obvious fake. Does that make it legit?... He didn't think so. FUn is just the beginning, if that's where you align yourself.

What caliber... What gas system... Give the full details on the barrel - something more than a 16" Faxon pencil with a .750 journal, and a 0.93" port diameter. We're missing alot of information here, on this barrel.

Exactly what he said. ^^^ Right up there. Plus pics. We need PICS of your gun, as many details as you think you can describe. After that, we'll need even more details. You better Brace yourself... Tightly, too.

I have two stories, brothers. The first one is very, very good, about the importance of Haditha Dam. You'll realize it quickly, once you watch this. This is a very KEY strategic terrain feature, at the beginning of the Iraq war. ^^^ Watch that. Tomorrow night, I'll post another story about that, and it will give you even more information about that strategic-level fight for that dam. Keeping that dam as it is, was, and should be, was a very important goal to achieve, in the early stages of the Iraq War. Rangers are Rangers, and they will get it done - but there is a very important piece of this puzzle that's not even talked about in this History Channel documentary. I'll give you that tomorrow night.

You guys are Savages...

He'll get back at you, and paint your rifle gold, when you're distracted at the fire...

I can see the carbon ring around your gas port in the barrel in that pic, and it's perfectly centered. 5/16" would be 0.3125", and that's not even possible for a gas port diameter. No way, no how. That carbon ring on your barrel is 0.125", because that's the diameter that the port in gas blocks are drilled, because that's the ID of a gas tube. Nothing will ever go over 0.125", because it's not gonna work, with the gas tube ID being the restriction. Always. If you ever see a gas port diameter over 0.125" - then that's a bad design. The barrel manufacturer should have upped the gas block journal diameter, to cut the gas port diameter down. 0.3125" for a gas port diameter isn't what you have - I can see it in the pic you posted. 0.3125" gas port diameter is unpossible.

I bet if you get enough "lean" in on that thing, and whiskey-throttle it, it'll turn. If someone here will buy it, I ride that motherfucker. I'll ride the hell out of it, even if it means more pins in a clavicle again. If it was a 2-stroke, it would get down...

Amen. Thus endeth the sermon.

^^^ I like that one, brother...

That looks like one painful ride, right there.

Either barrel length would work very well with a rifle gas system.

I tried looking up the specs on this projectile, on their website. They have 6 projectiles listed for .264/6.5, but a 121 grain solid copper isn't offered.

I was gonna state that - when he starts his own thread on this all, and doesn't continue it in the "Gas Port Information Thread"... Not the "Gas Port Guessing Thread..." No harm on you, brother - just on him. Wrong place to decide to launch your gas port questions - in an information thread...
