Exactly!

Do you reload ammunition? Are you a reloader?

Precision Reflex (PRI) sells complete Mk12 Mod 0 (Gen III or Gen II) and Mod H rifles - you just need to pick your optic and mount, and get it on. https://www.precisionreflex.com/rifle_packages_pr-8619.aspx

If anyone wants to build a Mk12, the heart of the entire system is the barrel, and you need a very good one. Don't waste the money on uber-expensive barrels, custom-this-and-that - just get a Ballistic Advantage Mk12 barrel - their SPR barrel. I have 4 of them now, Mod 1 is a 5.56 BA 18" SPR barrel, Heavy Grendel is a 6.5G BA 18" SPR barrel, Mod H is the 16" BA SPR Mod H barrel, and the .224 Valk is the 18" BA SPR barrel. @Matt.Cross Mk 12 Mod 1 is the 6.5 Grendel 18" BA SPR barrel. These things WORK, and they don't break the bank, compared to some other "Mk12 specialty barrels." Every one of mine is well under a 1MOA barrel, all day long. My Mod 0 is a Nordic Components 18" precision barrel, that was made by Wilson Arms (not Wilson Combat - different company). Here are the BA barrels that you'd need for one of these builds: 18" .223 Wylde SPR (Mk12 Mod 0 and Mod 1): https://www.ballisticadvantage.com/18-inch-223-wylde-spr-rifle-length-ss-premium-barrel-ops12.html 16: .223 Wylde Mod H SPR: https://www.ballisticadvantage.com/16-inch-223-wylde-spr-mid-length-ss-premium-barrel.html BA now offers them in black nitride now, as well: https://www.ballisticadvantage.com/ar15-barrels/premium-series/223-wylde-premium-black-series Here's the .224 Valkyrie in 18" SPR profile: https://www.ballisticadvantage.com/18-inch-224-valkyrie-spr-rifle-length-ss-premium-barrel.html Here's the Grendel in both 18" and 16" SPR profiles: https://www.ballisticadvantage.com/18-inch-65-grendel-spr-rifle-ss-premium-barrel.html https://www.ballisticadvantage.com/16-inch-65-grendel-spr-mid-ss-premium-barrel.html There is no reason to look at any other barrel manufacturer, if you want to build your own Mk12. There really isn't. You'll spend alot more money on something that won't really give you a giant benefit over a BA barrel - or you'll save alot more money on a shiit-barrel from someone selling cheap barrels, and it won't shoot anywhere close to the BA barrels.

^^^ That Mod H above is still a work in progress. It'll get finished, one day. Mk12s dominated the day for the High Angle portion at the last Fall Shoot.

It indeed is. Work of Art, and Function. Sharp eyes will catch something very specific in the pics of this front sight here... I'm with @blue109 on this. I'll never, ever use any Dick Swan parts, ever. There are people that go crazy using exact this-and-that, and I respect that. I'll never do it. I'll use correct major components, but I'll always default to my own personal preferences on a gun, too. Mk12 Mod 0 needs to be running the PRI handguard. Check. It also spec's a specific top rail - that I'll never use - but I'll use the PRI top rail, all day long. IMHO, I don't want to build a 100% period-correct weapon - I want the performance of that weapons platform. Another example - Mod 1s used the KAC rail. Yeah, I get it - I'd rather have the LaRue rail on there, and still make the gun function, as it was functionally designed. I'll stick to the principle of the gun - not the specific choice in it's original parts list. My Mk12 Mod 0 top, Mk12 Mod 1 middle, Mk12 Mod H bottom: The Mod H is a 6.5 Grendel, and it smokes the other two. Badly.

More on this, and entirely my own opinion, 100% and then some. The Mk12 was entirely designed around a certain load, a certain projectile, and a certain distance-to-hit ratio. Again, all my opinion - the Mk12 is the most perfect AR15-type gun ever developed. Nothing else in 5.56 will ever beat it - unless you come in here with some F-Class benchrest junk against it. Never has a better combat weapon ever been refined - the Mk12 is the pinnacle of 5.56 refinement.

He just can't contain himself... This is fucking EPIC... Wait for the SHOT Show report, fuckers. Rob, Greg and me are attending, as well as @JBMatt - pure chaos...

Wait for the blog in TFB about that one - That's "50 Shades of Gray" right there...

That's MY Shockwave, sent as the prototype to "mock things up..." Fucker teased me on the phone and told me that I had to WAIT FOR IT, AT SHOT,to see it... Busted, Rob... BAD BUSTED, brother... VERY GOOD CATCH, DOC!!!

Very badass article on the Mk12 from Monty LeClair. Very read-worthy, with a ton of great links in the article - it'll send you down that rabbit-hole, I'm warning you now... https://www.arbuildjunkie.com/mk12-spr-navy-seal-monty-leclair/ Here's another one - linked from that article ^^^ https://www.officialjackcarr.com/mk11-12-an-urban-snipers-best-friend/ Might as well just bust it all out... Here are the vid links from that article... ^^^ For the record, on the comments on that one - Vickers states, "Now Monty, you've got an interesting point, as far as you know the Navy never used any of the Mod 0 guns..." Monty states, "That's true, I've never seen any of the Mod 0 guns,... /clip/ ...the only ones I've seen in the inventory are the Mod 1s" Completely true Navy-wise, but that's not what Army did. US Army Special Forces started the Mod 0, and used them (5th Special Forces Group developed the weapon, from it's conception - as well as the "Mod-H", or the Mod-Holland, the 16" variant). 5th Special Forces Group started the entire concept, from soup-to-nuts, and got it rolling in the first place. US Army Special Forces use the Mod 0 - US Army Rangers use the Mod 1, and not the Mod 0. 5th SFG(A) further refined the gun to the 16" barrel, and that was the Mod-H. PRI (Precision Reflex) did all the mods of those gun to the Mod-H - PRI converted them. PRI built most of those Mod 0 guns in the first place, even though NSWC Crane was the proponent for the platform. Crane didn't assemble them - PRI did. PRI 100% did all the conversions from Mod 0 to Mod H, on all those guns. Just a piece of history. Just for the record...

Early night vision!....

This would be directly opposite of what really happens. DNP is on it. Dwell time. The longer your dwell time, the harder the recoil, and the more punishment on the cyclic components. Think about a gun with an 18" barrel, midlength gas or rifle length gas. Or carbine gas. The distance from the gas port location, to the end of the barrel, is "dwell time." That's the total amount of time that the barrel is feeding gas pressure to the bolt carrier, and it's also the amount of time that the barrel starts feeding gas pressure to the bolt carrier. You start the unlocking process too early, and you have BIG problems on your hands, as far as function goes. So, the closer the gas port is to the chamber, on a given barrel length, the sooner is tries to start unlocking the bolt, and the longer it provides "propulsion" to the bolt carrier. 18" rifle gas is gonna be the "softest" shooting. Moreso than 18" midlength gas. 18" carbine gas is gonna be a handful, it's gonna beat the shiit out of components, and beat your shoulder up. Now, think about trying out something with 18" pistol gas system - that's gonna SUCK to shoot, and you'll be breaking internal reciprocating parts in short order. The closer to the end of the barrel that the gas port is located - the larger gas port you need, to function the rifle. Recoil systems play heavily into this - the gas system and recoil system are independent of each other, i.e., you have carbine gas, doesn't mean you have to run carbine recoil systems. They're not tied together - but they MUST be balanced, and WORK together...

Ballistic Advantage Modern Series, Mk12 profile, 5.56 chamber, 1:7" twist. 18" 5.56 SPR Rifle Length AR 15 Barrel w/ Ops 12, Modern Series This one: https://www.ballisticadvantage.com/18-inch-556-spr-rifle-cmv-modern-barrel-ops12.html Gas port diameter is 0.095", 18" 5.56 barrel, rifle gas. This is very close to what an 18" rifle gas .308 Win barrel needs to be. Here's the barrel referenced:

That's a beautiful work of art, right there. I keep staring at the magwell on this one, Doc - that's so smooth...

Okay, we can deal with that. What about gas port diameters and recoil system details?

Here's the follow-up article from the next day: https://thebfd.co.nz/2020/01/trust-in-police-destroyed-by-politically-motivated-raid-against-young-family/

That's the Affliction. That's what we spread, brother. #31 is going together in a few days. Because.

Too late - you can't un-see it... 🤣

For the record, there's NOTHING about a beaver that is NOT SERIOUS. I'm just sayin'... Beavers are fuckin' SERIOUS. I'll paint that motherfucker, my brother.

Ron R2 is still on the hook for trapping us with the Monkey Shoulder... That was evil...

Gawd Dayum right, she is. For those that don't know, she'd whip this guy's ass growing up, chew his ass as he was older - and she'll STILL dig into his ass right this second, if she thinks he's doing something wrong. That Little Woman has no fear... She'd whup Jesse right now if he was doing something wrong... She's a fireball...

This is so awesome on so many levels - did the kid realize who it was that was helping him get this rifle together? That just blows my mind, thinking about that...

Did you hear bout the other .50 yet, brother? I'm not sure that I should say anything until next week, so I won't.
