THAT is awesome...

Good thing it WASN'T a beaver - cops woulda been cleaning that kid up with q-tips and sponges!

Lesson 65b. You snooze, you lose.

That gas tube looks too short. Get a pic straight down into the magwell so we can see how far back it extends into the upper receiver.

What grip. Name it, in case I missed it...

I tried to PM him on your behalf, and it came back as "can't receive messages" - you're screwed, man. Good luck in the hunt for the rail, though.

Mike fell asleep and almost took a mortar in the ass. He just doesn't realize that...

We did most of that stuff last trip - well, except for that weird Japanese-nipple-roman-candle thing. You just left too early...

That Noveske is 3 and a half bills...

Aaaaah, AAC, as well. From the above,if money was no object, I'd personally buy the Noveske barrel. If I couldn't swing the Noveske, it would definitely be Ballistic Advantage (and they are a Site Sponsor here, brother).

Noveske, Bison Armory, Ballistic Advantage, PSA, KAK. Not many choices for that length. TONS of choices for 7.5", if he decides to go that route, over 8.5".

Degrease it, and you can run M-Pro 7 in the meantime, and I'll get you hooked up with The Lube... I'll get you some pics of where the carrier wears the most - get the lube there, for sure.

That's NOT a good idea. Works for the Mk19 Grenade Machine Gun, but that's not the choice for the Big AR. No matter what the local shop said.

^^^ My ALL-TIME FAVORITE weapons system!

Cerakote goes on at 5/10,000" thick. Cerakote doesn't need to break in. The rest of the rifle does, but the Cerakote isn't gonna hold it up.

^^^ You are WAY good on that receiver extension. By FAR.

PM system works well. If he can't receive PMs, you might be SOL...

Yes. However, you could creatively chop the one you have, and it'll clear to fit.

DAMN!

I almost bought a new Sig M400 SWAT (LE/MIL-only model) today... I'm just sayin'... https://www.sigsauer.com/store/sigm400-swat-ap.html

MagPul MOE K2 grip - you'll like it. LaRue MBT-2S trigger - can't beat that thing for the price($125), and I like mine alot. Start with the Primary Arms red dot, this one: http://www.primaryarms.com/primary-arms-micro-dot-with-removable-base-eta-early-july-2016-md-rbgii Muzzle device - you ever gonna suppress this thing? Or just want a decent comp on there? Or, want to eliminate all muzzle flash? Talk to me, goose!

^^^ Exactly so. Gonna be tough to eyeball boresight a scope on a slug-only shotgun. Fastest way on that is laser. Same with "aiming aids" on pistols...

Just make sure that receiver extension is screwed into the lower far enough to properly capture the buffer retainer. If it's not, that buffer retainer WILL shoot out, while shooting the firearm, and it will jam something up, causing you grief... On the other issue with the port door - I'd grind the leading edge of that port door ball-and-detent housing, if it was mine, and test it out. I think that's the issue, as pointed out by others. Port doors are easy to replace...

Nah, you're good, brother. His last post was 31 Jan,and the last time he was here was 31 Jan. I was hoping he'd come back one more time to list his trigger in the For Sale section, but I don't think he'll be back anymore... Sucks, too - I was gonna offer him 50 feet of used garden hose for it.

^^^ That was part of Colt's "self-imposed ban," wasn't it? Along with larger trigger/hammer pins, and different pivot/takedown pins?
