Well, since the witch lost I was finally able to afford the Noveske Diplomat 7.5" with Noveske gen3 lower and flaming pig.

Now, I know folks say how weak 5.56 is in 7.5" but I'd probably not want to be on the other end of this one, even at 20 to 30 yards.

What would y'all recommend is the best ammo set up for this little guy, I'll post some pictures later....

My guess is that you'd want a light bullet to keep velocity as high as possible - maybe something in the 45 grain v-max or something like that. My son has a Form 1 in process right now for a 7.5" 5.56 SBR. It's not for me. I have a 10.5" SBR, but it shoots subsonic .300 Blackout all day long. But subs in 5.56/.223 tend not to cycle actions reliably, so full power ammo is your only real choice.

Thank TAM

I actually have some 75 gr hornady 5.56 in it now. My thinking was that heavier is better, but I can go lighter.

What about green tip IWi 66gr?

Thanks again!

Searching the web, I found that Novenske actually has his own signature ammo using Nosler bullets. He uses 55 and 60 gr. bullets. Info from folks who actually own the Diplomat suggest heavier bullets( 55-75 gr.). The 7.5 " barrel is described as worthless. The 10.5 " barrel is suggested as the minimum barrel which should be purchased, Just what I read.....I would have suggested lighter bullets also.

That's TAM and WTR.

I'll give them both a try and see which works better. I think that flaming pig will help the concussion a lot.

As for as 7.5" being worthless, well my intention for this little guy is CQC defense, less then 20-30 yard engagement. Not sure that 30 rds of 75 gr 5.56 coming out of tiny 7.5" 1:7 barrel is too bad.

I'd take it over my g26, which is on my side daily. ****Not saying I will CC this****

I would not care to be shot with one either. It was said they were great fun to plink with and were good out to 100 yards.....Sounds like fun to me.

I wasn't going to post here until I had more range and research time. I bought a 7.5" AR-15 pistol the morning of election day. Indirectly Andy C's fault, as have been many of my firearm purchases this year. My story and I'm sticking to it.

A 5.56 pistol was on my wish list, but way down in priority. Number one has been a Ruger Precision Rifle, but those things are as hard to find at the right price--and available--as hen's teeth. Too, I know I'll need to spring at least $1,000 for decent glass to do it justice, so that's held me back from searching very much.

Fast forward to a weekly Monday evening poker game (no money exchanged, mind you) on November 7. Ya think the topic of the election might come up?

Long story short, the question was presented: "What firearm purchase could you--and would you be willing to--make tomorrow morning that would be most upsetting to the left if Hillary Clinton were to be elected?"

No brainer for me.



I put a Millet M-Pulse red-dot on it, and used the Millet riser block. Shooting this thing ain't like a rifle or a pistol. First rifle-caliber firearm on which I will place no iron sights. The Millet riser block has a clear, rectangular opening along the rail; that's my BUS.

Firearms are tools. Tools are fit-for-purpose.

A 7.5" 5.56 is not fit-for-purpose beyond 100 yards, IMHO. Folks dissin' the ballistics have it wrong...somewhat.

An AR-15 pistol is not a rifle. Surprise: it's a pistol. And, at even 7.5", a pistol that has a longer barrel than most any other production handguns.

Are the ballistics compromised? You betcha.

I've steered toward heavier, HP ammo for the stated HD purpose.

Am I likely to need to shoot my AR-15 pistol at distances of 50 yards? Nope. But the potential is there.

So far, the verdict's out.

Congratulations Skiprr!


I tested my Diplomat yesterday on some leftover pumpkins at approximately 20 yards. The quick 30 rd dump results assured me that I've made a right choice for CQC / Home Defense.

I think that flaming pig is awesome. There was very little flash, muzzle was steady, and concussion was not as bad as I thought it would be. Still very very loud but not ridiculous.

So you got a version of the somewhat controversial SIG SAB for yours, as well. I promise I will never use mine as an SBR. Never ever.

The one range visit I had with mine so far showed me that it does put out an impressive fireball. At contact distance, that alone might flash-burn about a two-foot diameter. Bad guy wouldn't be happy about taking a 2,300 fps round and being set on fire at the same time. Presents a definite issue for the shooter in low- or no-light conditions, though. Not a huge amount more than a 16" AR, but it's a bigger flash and closer to your eyes.

And it's also loud. As you noted, not ridiculously so, but louder than an AR rifle and most handguns. TAM's suppressed .300 Blackout SBR would be the better choice, but I didn't want to add a new caliber to the mix and I didn't want to go through the red tape of an SBR permit. I have a bunch of 5.56 magazines and I add ammo to that collection when I can. Even though I can't suppress it, I still prefer the 5.56 for that reason.

Also as you noted, it's surprisingly shootable. Not using the SAB as an SBR stock, of course. Even at a private range, I would never do that. Even one-handed using the forearm brace I can fire multiple-round bursts at 25 yards with good accuracy. And the little guy never failed to cycle in it's single outing, so far, with just under 200 rounds of mixed ammo. Signs point to "yes."

The Millet RDS is small, has a 5 MOA dot, and I have it mounted just forward of the ejection port. It works well and adds virtually no weight, but it's a little slower in target acquisition than I'd like. I could mount it farther to the rear, which would help, but I'd rather not. We'll see. Two other options: move one of my EOTechs to the gun (significantly heavier) and/or look at a laser like a TLR 4. I've never bothered with trying a laser on any firearm, but this may be the one. Again, we'll see.

I've ordered some Hornady 5.56 75 grain HD SBR Black--http://www.hornady.com/store/5.56-NATO- ... SBR-Black/; not the cheapest stuff on the block--and will try it next range outing. If it shoots as expected, that's probably what I'll charge the little guy with. It's supposed to reduce both muzzle flash and sound without sacrificing muzzle velocity.

I thought briefly about trying to modify a nylon drop-leg holster for it; it is a pistol, after all. But that thought was very brief: not only impractical, but seemed lumped with the idea of carrying an LTC badge. I am considering the notion of a single-point sling for it, though. No immediately apparent options for attachment so that, too, will need further consideration. The other plus is that it measures exactly 22 7/8 inches stem to stern. For carry, it'll drop into a variety of small bags that I have.

Oh, and BTW, I'm not an FDE guy, but I like the idea of this lower being visibly and clearly different from the ones that can be matched with a rifle upper. No possible confusion.

This is the closest thing I've come to a firearm impulse buy in a couple of decades. So far, no buyer's remorse. Fun to shoot, probably will serve a purpose. And it just looks gnarly.

I was under the impression there's nothing wrong with putting a rifle upper on a pistol lower. Rather, the legal pitfall is putting the short upper on a rifle lower.

I think you're right. A no go is putting a pistol upper on a rifle lower. It's the craziest thing, like a 7.5" or 10.5" barrel will do more damage

If anything, longer barreled rifles produce more velocity etc...


Oh well. Law of the Land. For now. I hope...

Yeppers. Not illegal; doing it the other way around is the illegal part.

But not a good idea because an AR pistol can't be shouldered, and handling a 16"+ barrel on a lower that can't be placed against the shoulder is more than a little unwieldy. Went with the 7.5" barrel because I thought even a 10.5" was too long to handle easily as a pistol.

I have a variety of uppers and lowers (only the one pistol, though) and the SIG brace sorta looks like a stock when viewed from the side. I'm old. Eyesight ain't what it once was. I would not want to accidentally put a rifle receiver under that short-barreled upper.

My original sentence should have been, "I like the idea of this lower being visibly and clearly different from my rifle lowers." Shorter, simpler, and less confusing. I need to learn to self-edit as well as TAM does.
