Nice looking setup, and well done. Just so you know, though, and it's discussed as common knowledge here - that's not an AR-10, not even close. Armalite makes the AR-10, and it's a completely different platform that the DPMS LR-308-based Aero M5 that you have. For example, I'll say this - pin an Armalite AR-10 upper receiver to your Aero M5 lower, and see if it fits. It won't. There are 3 basic platforms for these "larger ARs," and they are Armalite AR-10, DPMS LR-308, and Rock River Arms LAR-8. There are tons of different specialized platforms as well, but those are the three main platforms. So, just so you know, you don't have an "AR-10" in the least. Confusion amongst the platforms will only screw you over in the future, when you're looking for upper receiver parts and such. That's the entire reason that this site is named ".308AR.com" ...

I like that on a scale of 10, it's a 12...

Go home at 2 with a 10... Wake up at 10 with a 2... Beer Googles FTW...

You still sending Hornady your data on their defective ELD-M tips that dent and break when chambering?...

No need for them, if you need Armalite-length gas tubes. Just buy the Armalite gas tubes. Custom gas tubes is where they shine, and nobody else does that besides them - and gets it right. They do. They shine is a WHOLE LOT of other areas, in custom guns and quality parts, but you don't "have to have" a WOA gas tube to make your gun run. Glad to see you using their real name now, instead of just calling them "Oak," like you were before... See what you have first, brother, for a gas tube length. See what you need...

Is that the Alexander Arms barrel, 9/16x24 threading?

I did all that, building the load. I went as high as I could go on that original 18" gun (first Grendel) and made the load. Accuracy node at 28.5gr // AA2520. After that, I saw some pretty severe pressure signs before I hit the next accuracy node, so I stopped and called it there. Next Grendel that was up was the 12.5" build, and it was a beast. I thought I saw pressure signs with the exact same load (already had my load, so test it in the new short gun). At that point, I backed the load down to the next lower accuracy node, and that was 27.5gr // AA2520. I thought I was running hot ammo before, so I backed it down. Next node was exactly 1.0 full grain lower (original 18" gun). Then I built another Grendel, a lighter 18" gun over the original Mk12-ish heavy gun. 27.5 did good, brass still looked like the first 28.5 loads I made. Then I built a 16" M4 Grendel - brass was the same. Then I built a 16" Mk12 Mod H Grendel - brass looked the same. When @Matt.Cross and I had the chance to run our 18" Grendels (his is a Mk12 Mod 1, and mine is Mk12-ish) through a chrono, with HIM running factory Hornady Black ammo - he was smoking me by 150fps... WTF... At that point, I re-looked all my brass pics, load data, and reloaded some of those original 28.5s again, and ran them through the same chrono. Lo and behold - the numbers I reported above. It wasn't pressure signs I was seeing, with all 5 Grendels doing the same thing to brass - it's just what Grendels do to brass. I'm back on 28.5 grains, and it's worth it. There's no need for me to go back and reload everything up again, between 27.5 and 28.5 - I've already done that in the original load development. I'm not concerned about what load charge the 18" passes up the 16", on the way up again, because the accuracy between 27.5 and 28.5 was garbage. For me, that's just gonna be a waste of powder and projectiles - and time. There were zero cycling issues on any of the 5 Grendels, from 27.5 through 28.5. None.

The Black Tip. These are gonna be HARD to find, brother, based on the shiit-show a few years ago, banning AP ammo, and the Libs/Idiots/Gun-Grabbers trying to lump M855/SS109 into that batch of regulations. That was what - 2015? Finding those things is gonna be tough, IMHO.

You played with gas adjustment yet? When you lock it back on your own, are you making sure you've pushed the bottom of that bolt catch in all the way?

Yankee Hill makes a fantastic clamp-on lo-pro gas block, and it's cheap... https://yhm.net/low-profile-gas-block-pinch-screw.html

The Trunk Monkey is my hero. That was a PNW car dealership that made all those - there are several more...

That's a 5.56 part, specifically. Only. it will not work in a .308AR, at all.

^^^ You gotta watch those Poblanos, though - they're "green" when they're "milder" but they turn red, too. And then, they're pretty fucking hot. They're a mainstay in my "pepper garden plot." Get 'em before they get red... or they turn into the "Anchos..." For real. They don't need to look "dried up" like that pic above - those fuckers start to turn, you better pick them off the plant... Watch 'em close, if you grow them...

There's gotta be a way to bang that Ostrich...

I LOVE THIS THREAD!!!...

Oh, but you did. You did take it personal. And, you think that because others use my first name, that you think you're on that first-name basis with me. You are not. I've never met you, I don't know you. I've never shot with you, nor hosted you in my house, nor have I traveled to meet you just because I had some time off work - and I missed hanging out with you, because our "other scheduled trips" just fell through, throughout the year, for whatever reasons between your life and my life. Life gets hectic, and WE that do that, get that, and get together when the time allows us... For the comment in the red. Just because there are close bonds here, formed through years and years of personal contact and friendships, that have been developed, with real friends, real name use, personal visits, and trips across this country - both ways, east and west - doesn't mean that someone can walk in here and just plop their ass on the couch in someone's living room and just make themselves at home. You don't knock on my door, and I open it, and you walk in and tell me to get you a beer. Others here CAN do that, and many of them can do that unannounced. Show up, knock with no-notice, and yell at the top of their lungs, "Gimme a beer, BITCH!!!" There are some here that are welcome to do that. They'll get greeted with a holstered pistol, first, after I holster it, then a pants-down hug. And I'll fetch them that beer that they demanded, too. Second one is on them - they already know where my fridge is. You are not in that crowd. I don't know you, never met you, and don't show up at my house - though that invitation is completely understood, amongst a very small group of people here. That group could be larger, and it gets larger every year, that time goes by - amongst all of us. As of now, you are not that person. For some reason, I can't understand how you came in here, plopped your ass down on the couch, and you can think you can address me by my first name. You seem to think that you can take some liberties here that others take, just by being here. "Barge your way in" or whatever you think. It doesn't work that way. I sincerely hope you get that.

Your picture shows plenty of engagement between the bolt catch and the bolt face. Please explain this statement in more detail - need to know more of what you're talking about here, as to what the malfunction is... What brand magazines are you running?... You cannot possibly provide "too many" details on this, so let your mind run free, and tell us everything...

You'll have to have that one Cerakoted someplace else. Aero doesn't offer Burnt Bronze as a factory option, direct from them. Buy it in black, it's cheaper that way - then have someone Cerakote it for you. Or do it yourself - Cerakote is easy, if you get the "prep" right.

It's all about attention to detail, considering this is a Grendel mag thread, right in the title. I'm just sayin'.

What was their capacity? I've never had this problem with the ASCs for Grendel, and I'm not doubting you, in the least. The only Grendel ASCs I have are the 25s. The only other Grendel mags I have are the 17-round E-Landers, either E-Lander marked or Alexander Arms-marked.

Somebody need to jump on this - this is a great barrel.

Well, Shiit then - Guess I read, and didn't even look at the first pic in your first post in this thread...

You absolutely positive about that, brother? Most common are .936, when you get that huge. That's gonna narrow your gas block sources, if it's .940"...

It's a pretty humbling experience, having him here, and just being able to say "he's a friend." You know, his wallet and all... If you look through this specific section here - he wrote ALL of those. All of them... https://forum.308ar.com/forum/125-raleys-tech-corner/
