Let's see how it runs. There's a bunch of number that are off, but risk it - you paid for it. Buffer weight should be 5.4oz, the list 5.0oz. Least I've ever made run right was 5.15oz, for a buffer. So, the expensive buffer is light. Let's risk it and see what happens. JP is Complicating Shiit With Complicated Shiit, and this says it all right here: The JPSCS2-10 is designed to work in standard 7-inch M16/M4-length buffer extension tubes on .308 AR-type rifles like the DPMS LR-308. Armalite .308 rifles, likewise, use these standard M16 extension tubes with rifle-length stocks, so this unit will function normally when installed with the supplied spacer. However, Armalite's .308 carbines use a slightly longer, non-standard carbine extension tube. The JPSCS2-10 can still be used with these extension tubes by installing the spacer, which must be modified to fit. Alternately, the system will function readily if the longer Armalite carbine tube is replaced with a standard 7-inch .223 carbine extension tube. That's their own description of this part that you have. It's ironic that they state the Armalite .308 carbine uses a slightly longer, NON-STANDARD extension tube... I LMAO over that... The Armalite AR-10 Carbine Receiver Extension IS the standard, for .308ARs... You're dabbling in Gamer-Gun shiit, with that recoil system -tailored for a certain load, certain gun, certain projectile speed - for matches, games, and playing around. That's cool. If you're a Gamer, and you use your gun for making money in competitions, against others, for determining hits on steel with major power factor, and less felt recoil. You're using Race Gun parts to build your gun, that work for Race Guns. What are you looking at from this gun? what is your intent for this gun? What are you gonna use it for, and what do you want it to do for you?

This one is pretty badass, because this covers the same timeframe that I was in 1st SFG(A). It's pretty cool, hearing this. What this guy is describing and talking about - some of the people - I worked with them. I know some of the dudes he's talking about. Pretty much mind-blown listening to this. For the record, the 1st SFG(A) CIF Team is (was) C/1/1, stationed in Oki. He talks about one of the guys that got his eye shot out during a training rotation - that was one of the guys that I worked with for a long time, talked him into really doing the real job, and getting Ranger qualified, as a support guy - like we're supposed to - and he did. He took that eye loss pretty hard. I get it - I know, and I talked to him for many days and hours about it, on the phone, after it happened. Potentially, you're out of the Army, without one of your eyeballs. I gave him possible options, all things considered. He stayed in, and went on to do greater things, with one eye. He turned into a Terminator Badass, with one eyeball, and went on to do great things for this country. I think I talked about it before, but he had a fake eyeball, battery-powered, that he could pop in, and it really was a Terminator eyeball, glowing red when it was turned on... Scared motherfuckers in a bar, when they saw that shiiit... His first name was Melborne, his name in Group was Meb. It was just easier that way. I won't give his last name, because I have no idea if he's even working in this field anymore, or with any agency these days. He was crippled, potentially getting kicked out for disability, but went on to achieve more than any of us did, with the direction he went. Badass. Listen to this one, it's pretty cool. It's REALLY cool for me, because I'm recognizing names, dates, deployments... What a ride...

For the record, I own 5 Wilson Combat barrels, and not one of them have a tight chamber. That's 5 barrels over 4 different calibers. Wilson Combat makes their barrels with their own Match Chamber, and it's where it needs to be. Match Chambers are definitely not loose chambers - they're tighter than a mass produced chamber, for a reason. I've never had an issue with headspace from one of their barrels, and a Toolcraft bolt. Not once. They don't have gas ports figured out, but that's easily solved. That's my $0.02 on WC barrels - they're accurate as hell, true match barrels.

Nope - that's the beauty of the tank trap - depending on what type of rifle you're using determines where you have to shoot from. You as the shooter need to figure out how to solve that problem. Here's an example of what I'm talking about - Open and Restricted Class shooters have to shoot from ABOVE the intersection of the sections of the tank trap. Tactical and Limited Class shooters can shoot from anywhere touching the tank trap - those guys can actually prone out on the ground, and touch the bottom of the leg of the trap with their elbow... Different classes, different rules - gotta figure out what you're gonna do to solve this shooting problem. SO, you think you have a good plan, and the timer goes off... BEEP!!! Click until this is big enough to read - it's about 3 clicks I think... Scuba Steve is a badass - he can fabricate ANYTHING. He's a great dude, great friend, massive skills.

Wilson Combat Tactical Hunter barrel in 7mm-08 caliber. 18" Rifle Gas, 0.750" gas block journal diameter. Ships with a gas port that 0.076". I'll check some math and see if this is gonna work.

In that case, just a picture of the JP part number. We can look it up and see what it's supposed to replicate.

That's perfect - that means Lilja is drilling the AR15 gas port location. Good info.

Yep, love it, brother. For the Spring Shoot, we'll have 2 tank traps, the Sex Swing, the PRS Barricade that Matt brought out for the Fall Shoot, we have several shooting mats for prone fire.... We could put together some hellish timed stages to shoot, play through, practice, and train on different shooting positions. Gonna be fun!

Your gun didn't like the AR15 Midlength gas tube very much. It's clearly seen that the gas key on the BCG struck that tube. That's why the Height Over Bore thing that I bring up often, is actually important. Here's a pic of what I'm talking about - click it, it gets bigger:

That's an AR15 Midlength gas tube - got a pic of where it ends in the cam pin cutout in the upper receiver?

Nope, just a picture of the buffer next to a tape measure, in order to see the OAL. We can figure out the buffer body material, and determine how much it should weigh, based on that.

The important weight is the buffer. Just get a pic of it, and it's length. Manufacturers commonly don't list correct weights.

Nope, somebody tried to sell one to @JBMatt for $75. So, he bought the steel for $31, took it to Scuba Steve, told him how he wanted it, and Scuba welded it up. He told Matt that right after he finished what he wanted, he made one up for himself, too... Matt picked up a 8ft 4x4 and 10ft 4x4 - and we cut the stuff and put it together. Works pretty damn well, rock solid, with only wood screws holding it in place right now. I can literally climb up on top of it, and it doesn't wiggle. It'll get 1/2" lag bolts installed, through the brackets, one per leg.

With the shiit you have going on, you need to read this thread very first, and comply with every single detail that it requests. This is the only way we go forward. There is no other way to help you, unless you do this. Read this, soak it in, understand it - then make your reply. Here it is:

That's amazing - but you failed to mention what the gas system length was, entirely. State the gas system type (on a .308 AR it's either gonna be midlength gas or rifle gas), and the length of your gas tube, to make this post relevant for anyone to use in the future. Otherwise - worthless. Most pertinent detail ever, in determining gas port sizing - gas system length. Missing here.

Clicked your link, and still got the same. This is what I see:

I'm getting no access, brother. Link denies me. I wanna see this one.

You're making me happy, man. I like the way this story is going. Very well done.

Get the .300 Win Mag barrel for that sexy biotch, brother. Fast, too. You need that barrel.

Ramp Monkeys and Bag Smashers...

Yep, I concur...

You, my man, and @Matt.Cross - just trouble makers for air travel hospitality professionals...

BINGO! Brother!!! That's exactly what it is, and it has a purpose. Tank Trap. @JBMatt

No suggestions, really. You have a good plan, and that plan will work for what you want the gun to do, and expect of it. Run with what you have, and run the gun for awhile. I'll say this - it's Saturday. Get that BCG underneath oil - MobileOne synthetic is the suggestion, so that's gonna run you $14-ish for a quart. Put that BCG underwater (under oil) - see if it'll fit into a tupperware container. Those things are cheap, and work. And you can put the lid on when you're done. Let it soak until Monday - but get that thing out of there and hang it over your oil container - let the excess drip out of it. You don't want to pull it out of the container of oil, then go straight into the gun, and start shooting. That shiit will go everywhere as soon as you pull the trigger the first time. Hang it, let the excess go by gravity for a 24-hr period, then it's ready to go into the gun and head to the range for it's first trip.

Can anybody guess what this is?
