Great video. I think they might’ve improved those imperfections on the Geissele that you name off. The one I’m looking at right now doesn’t have the rib by the buffer tube goes. This one also has a slight notch where the trigger guard hole is, but not as defined as the Aero.

I think they might have two different sources

as someone who is in the manufacturing business (ffl/sot) and has a few years of mil/le machine gun build/repair racked up i will tell you right now that Aero is ok but geisselle is top notch service grade gear.ive put the mics to about 1000 receivers and logged tolerances, along with many autopsys on clapped out law enforcement machine guns and this i will tell you from 100% hands on experience... Geisselle, Noveske, LWRC, Spikes,and obviously KAC will outlast an aero in every way under heavy operating stress. .you get what you pay for.

I believe that that has been your experience, but if you go through my videos, you will find one where I measure the pivot lug slot to be under 495. I have handled three of their receivers personally, and none of them met the minimum half inch. I also used an Eddy current probe to measure the coding thickness on the black one, and it is not even close to the minimum on the Print.

I remember when LRB was the cheap solution. Very rough. I can't remember if they were high or low shelf. But you could get them cheap. I don't think they make them anymore. The Anderson's are the ones surprising me of late. When they first came out they were not exactly steller. Then the new ones seem to be really descent.

Used to be able to see them all over the place in Gulfport MS. Now can't find them. Andersons are plentiful. I bought two. And had my buddy pin gauge them. He's a armorer. (We served together in the Marines.) Worked for DSS as a armorer and trainer. And EAG as the same. And was lead armorer at LWRC. He said they were good to go and in spec. But no they are not as nice as Aero's. But niceties are not as important as functionality to me. How I found your channel was the Sionics BCG popped up in my feed. I'm kinda a Sionics fan boy along with BCM and Colt. But I seen your review of that first Sionics carrier. Which they get from Microbest. And Microbest doesn't machine their stuff for looks. They function though. I have a BCM that has waves in the machining. Functions fine. I don't have a Np3 carrier. I don't buy into not having to lube a bolt carrier assembly. And while I have seen these coatings will function. So does lube. And lube isn't dry. And there isn't two parts sliding on each other dry. So I tend to stick mostly with phosphate carriers cause they hold lube well. And when I clean them I throw them in a 50/50 solution of Simple Green and water. And let them soak. And I don't scrub them at all. Just wipe them off and dry them and reapply lube.

That symbol is the company that sourced the raw material, the real manufacture has to still mill out and finish the product, and there is way more than 4 of them it's just as of right now the 4 we see are the ones we receive. Search "upper forge markings" and there should a link that gives you a table. The "triangle is really a stylized H and stands for Anchor Harvey, the Square is BAFE and so on. Those markings don't really mean anything unless you are trying to source all parts from a certain factory like a lot of older M16s and M4, so unless you are trying to make a service rifle those markings mean nothing.

Nice, and brownells sells auto sears, along with the trigger, disconnector, and selector for select fire. And you can find jigs that sit in the selector hole to drill the forbidden 3rd hole for the auto sear pin. do with that information what you will.

Hello, Thank you very much. Indeed, you are right, I measured well with the caliper, the wall of the magazine is about 2.15 millimeters and the wall in the trigger is about 2.55 millimeters. With these values do you think it remains robust? Can it withstand a shot in full car although it is in semi car?

I hope you will inform me about this Geissele automatics and be able to tell me or not if I made a good choice for 2900 €? Merci beaucoup. Best regards

That's the design, it seems your receiver is made correctly. Ar15 is not tough a gun as some, but geissele is a fine ar15.

Hello, I am a sports shooter and I am French living in France. I just received my Geissele automatics super Duty in 14.5 inches. I am a little disappointed because the thickness of the lower is 1.5 millimeters thick, the thickness of an AK 47. Compare to other brands like Daniel defense or Aero precision, or colt it’s very, very thin. It’s a 2023 model. I saw in youtube other Geissele automatics that are thicker. Do you think that the fact that it is very thin can be a robustness problem? 1.5 millimeters is very, very thin. Do you think I made the right choice? Merci beaucoup. Best regards

@whattheshit4664

3 ай бұрын

Are you sure you are measuring the thickness accurately? The thinnest part of the magazine well should be about 2mm, and the trigger cavity wall should be 2.25+mm. If I got a receiver, that were1.5 mm thick i would be concerned for sure. Please note that sometimes the magazine well is off to the side so that one wall is thinner than the other. This is all causes some misalignment between upper and lower receiver. I stay away from those.

It’s not like the original m16 where it it’s a 90 degree angle from the base of the pivot lug. It’s not glossy, it’s more of a satin black (with a very slight pearlescent sheen in the anodizing). Slightly rougher texture, not as smooth feeling as my bcm upper receiver. The “beaver tail” spot right above the grip has the center machining line visible though, some receivers have that spot perfectly rounded together. It’s an 8/10 receiver or 9/10 if you value the m16 pocket and no visible markings. There is some slight play between my bcm upper and lower though, so I think SOLGW will be better in that regard.

I feel like their legal counsels may be somewhat responsible for it. The federal definition of a machine gun includes a weapon that "is designed to shoot automatically, without manual reloading, by a single function of the trigger." See 26 USC 5845(b). The ATF has interpreted the phrase "designed to shoot" to mean "possessing a design feature such that simple modification or the elimination of certain parts would render the gun to shoot automatically. See ATF Rul. 82-8. Most companies don't want to get into legal trouble with the government, especially if they are engaged in a strictly regulated and politically controversial industry. They may also be afraid that someone with a simple drill would drill the third hole and use it in a crime that then becomes publicized. Daniel Defense has come under some scrutiny since the Uvalde shooting. Although I don't agree with the law or the anti-gun side at all, that is the current political environment we live in.
