Yep, I concur...

It's in stock at DSG Arms, brother, right now, as I type this... 8 bucks... https://dsgarms.com/armea1095 Also, FWIW, Randy Luth makes solid products, and Primary Arms is a very, very good vendor. Hell, I'd say they are a great vendor. You will be okay. Measure the buffer when you get it, and make sure it's 5.200"long, and not 5.900" long - you're good.

Custom gas tube. That's about it.

Welcome - from what I could find on their website, this is AR15 stuff here... You'll need to change out the buffer and spring in order to get that extension to work on the 308. Just a heads up.

Hell, I thought you were telling me that the data I posted on the EA1095 was probably an AR15 spring... I misread that, but you quoted me that way...

If you do, you are doomed to repeat it. Lots of guys on planes tonight, 29 years ago. Getting ready to deliver a well deserved, bigtime asswhoopin'.

Nunchucks ban is unconstitutional, ruled on by a Fed Judge. https://www.foxnews.com/us/federal-judge-rules-new-york-nunchucks-ban-unconstitutional NEW YORK – A 1974 New York state ban on nunchucks that was put into place over fears that youth inspired by martial arts movies would create widespread mayhem is unconstitutional under the Second Amendment, a federal court has ruled. Judge Pamela Chen issued her ruling Friday in a Brooklyn federal court on the martial arts weapon made famous by Bruce Lee. The plaintiff, James Maloney, started his legal quest after being charged with possession of nunchucks in his home in 2000. He initially filed a complaint in 2003 and appealed all the way to the U.S. Supreme Court when the case went against him. The Supreme Court in 2010 remanded the case back down to be reconsidered in light of a Second Amendment decision it had made in another case, and Maloney filed an amended complaint later that year. Maloney had been focused on getting the part of the law overturned that banned nunchucks, two rigid rods connected at one end by a chain or rope, even in private homes. In her ruling, Chen said the court couldn't simply take that part out, and ruled that the state's law as it pertained to possessing nunchucks as well as to manufacturing, transporting or disposing of them was in violation of the Second Amendment. The ruling went over the history of the ban, and said it "arose out of a concern that, as a result of the rising popularity `of` Kung Fu' movies and shows,' `various circles of the state's youth' -- including` muggers and street gangs' -- were `widely' using nunchaku to cause` many serious injuries."' In an email to The Associated Press, Maloney said "perhaps the most amazing thing" was getting more relief than he had asked for. Maloney, a professor at the State University of New York's Maritime College, said some of his motivation was outrage. "How could a state simply ban any and all possession of a weapon that had a long and proud history as a martial-arts weapon, with recreational, therapeutic and self-defense utility," he said. Maloney also wanted to teach a form of martial art using nunchucks that he created, which he calls "Shafan Ha Lavan" to his sons, the ruling said. The suit names the Nassau County district attorney as a defendant. The county's lawyer had no immediate comment.

Might not be able to measure from there. I just did a monster post about this in another thread about it - hit the Ceratac build thread, man.

You need to measure opposite where that keyway is - at the top of the extension. There are alot of extensions are flared out at the bottom, to better capture the buffer retainer. Can't really tell from that pic, but the bottom, near the keyway, looks flared out there. You need to measure opposite that, at the top of the extension, as it would be mounted in a lower receiver. Look at this one, for example - not only is it extended at the bottom - that HAS to be slotted for the buffer retainer: This one is definitely extended at the bottom, to capture that buffer retainer better: Your bolt will still lock back - the face of the bolt travels further back, beyond the bolt catch, than that 1/16" of difference will make - but it might not pick up the next round from the mag, or something else weird - especially in a .308AR... That 7.000" internal depth is from a real TDP - Technical Data Package - the real blueprint, for the M16 and M4. I don't get why manufacturers think they can "just get close" or whatever they are thinking, and you as the consumer will have a fully functional weapons platform. You'll have issues with it, in some sort or fashion, if it's short - or long. Then, we'll be trying to figure it out. I had functional issues on one that was 7.100" internal depth, from a very well known, highly reputable manufacturer. Once I figured it out - it went in the trash. We even had one guy here try to argue that the 7.000" internal depth on an AR15 carbine receiver extension was "the starting point..." WTF?! It's not the starting point, beginning point, "almost point" - is it THE point that you need to hit on an AR15 Carbine receiver extension. There's no plus or minus, when you want it to operate as designed. This is the very reason I use 3 out of 4 Armalite AR-10 Carbine Recoil Systems in the guns I have - the genuine parts, from the specs from the real designer of this platform, will not have this issue. The other 1 out of 4 is using something different, in a 7.000" internal depth mil-spec AR15 carbine receiver extension, so I could test that system out with other known good parts. And it works, in the .260 Rem. That's exactly where my own endorsement of the Sprinco Orange spring comes in, when you use a heavy 2.500" buffer (gotta be damn close to 5.4oz weight). People give me alot of shiit for this receiver extension BS and recoil system BS that I go through, and I don't get that stuff wrong. The numbers that really work, are the numbers that I preach. When something funky is happening with weapons operation, I can trace that down pretty quick with a few measurement details. That goes for recoil systems, and gas systems. Off that box now...

I wouldn't jump to that right away, like most people do. Verify what you have for a recoil system, first, then move to your gas system - unless that gas tube is short. That's an easy visual inspection, and easy correction. You shouldn't NEED an adjustable gas block for a basic, functional .308AR rifle. That's a want, not a need...

Shim that thing with strips of aluminum, cut from a soda can...

I love Iron Sight NM setups. Just love them. That's a SCORE, brother!!!

Upper receiver cut for the barrel index pin a tight fit, or sloppy? If it's a tight fit, I can't imagine that barrel turning when you tighten that barrel nut...

6 15/16" doesn't meet the 7.000" internal requirement for an AR15, brother. It's short. Can that thing, for real...

Glad you're doing good, Brother Jeff! Don't let Char take advantage of you in this condition. Watch her like a hawk, man!

Shoot, brother - I'm just glad to see it running, like it's supposed to run. You did well on that gun.

Was the gas tube installed, when the nut was torqued down? Did it twist the gas tube in the upper? That'll stop the BCG from going into battery, for sure. When the gas key hits the gas tube end, because the gas tube moved. Check the gas tube, and see if it's centered in the upper. Remove the bolt from the BCG, and see if the BCG will go all the way forward, with no bolt in it - the charging handle will still bring it back, don't worry about that. Charging handle doesn't care if a bolt is in the BCG or not. Pics...

I highly doubt it. The AR15 Carbine spring should be 39 coils, 11.25" relaxed length, 0.072" wire diameter, and compress length of 2.808". The Armalite EA1095 spring ain't no AR15 Carbine spring, that's for sure.

Both those internal depths are bad, and won't work for anything. It eihter needs to be a 7.000" internal depth for an AR15 extension, or 7 5/8" internal depth for the Armalite AR-10 Carbine extension (and known like parts). Those two numbers you guys reported above won't work for anything. Well, they'll make great paperweights.

Armalite AR-10 Carbine gas tube is 12 1/16" long.

That was excellent...

34 coils and 13.75" relaxed. 0.072" wire diameter, and it compresses to 2.448" before coil bind...

^^^ Roger is THE man.

Good job, man - you will NOT be a victim of Lesson 65b. For those that don't know that particular lesson... Lesson 65b - "You snooze, you lose."
