I just need a scope, but otherwise my prototype USMC IAR is finally complete! It has an extremely rare KAC Heat Rail handguard, 1 of only a handful in private collections. I got the KAC Heat Rail about 7 years ago, and I've been actively trying to build this rifle for the past 3 years. It's now finally come together! The upper and lower are actually from a factory tanodized Colt 6921 donor rifle, and this is probably the only KAC Heat Rail prototype USMC IAR ever built with these tanodized Colt 6921 upper/lower receivers. The few other rifles that have been completed by collectors have been built with cerakoted receivers. So, this is literally a one-of-a-kind clone build!
The top black rifle is another type of prototype USMC IAR. The black IAR has a Colt handguard, whereas the tanodized IAR has the KAC handguard. The black IAR has a 100% original prototype complete upper (1 of 10 that has the markings on the left side of the upper receiver). The Elcan SU-269 optic on the black IAR is original USMC used surplus. The original SU-269 scope is in phenomenal condition, especially for being USMC used. It's also one of only a few in private hands, so it's pretty rare!
The tanodized KAC IAR couldn't have been built without help from Neal at Modern Arms Resources! He's the reason this rifle was built, and he did an amazing job finding the parts and getting it built to the original prototype specs! Thanks, Neal! @ringer706

Looks like the arca rail from CMT. They’re beefy.
CMT ARCA as mentioned, no complaints at all. It has all the perks of having an ARCA on the bottom of your rail.
My "Mock 12 mod H" from todays range trip.
Original Secret Service used KAC SR16 uppers (URX2 and URX3.1) with KAC NT4 silencers on KAC SR15 SBR lowers:
14.5" Criterion with P&W HUXWRX flash hider. Rogue Ops billet receiver set. Geissele MK 16 rail. JP FMOS bolt carrier group. Radian charging handle. TriggerTech Adaptable trigger set to 2.5 LB. BCM MK 2 recoil system. Nightforce NX8 in Reptilia mount.
Nothing fancy super duty 11.5

Finally ordered a real ACOG for my SBR. I had been running a knock off, gun show special one (red chevron reticle), and for the longest time, I wasn’t going to worry about it, but I got this one almost $400 off through Optics Planet, and now I get it.
Thing is so freaking clear. I went with the 4x32 green horseshoe fiber optic reticle and I love it. It’s the rifle I carry in my go bag, but it almost got moved down the bench after I built my 10.5” .300BLK (which has an Eotech 512 with a G45), but I think it’s staying.

A Mega Proof build with a generic bulk loaded 77smk. Love this rifle.
I did move it left on 4&5

Just wondering if this optic setup looks dumb or not? This is my 10.5” .300BLK “pistol” build that I had to SBR because I haven’t found a pistol brace I like yet, so I threw a SOPMOD on it. But I had the 512 in the cabinet from an old build, so I ordered a G45 for it. As you can see from the second picture, the set up works. It works very well, that target is from 50 yards.
Reason I ask is because every Eotech with magnifier I see nowadays it’s the EXPS3 with the G45, and that set up looks so damn cool. The 512 is left over from my dad’s Block II clone I inherited after he passed (long story - I didn’t realize it was a perfect Block II clone until after it was disassembled and rebuilt into two different rifles), and it was just collecting dust in my cabinet so I wanted to use it on something.

11.5" barrel makes for a short range weapon, so a 17" bayonet gives added reach...
My Mark12 mod H build.
Highlights include, WOA SPR barrel, Acheron Suppressor, Vortex Razor G3 1-10x, Nightforce ultralight rings and Socom stock.
It may get a Colt lower in the future. But for now, I see it as finished. Massive amounts of shooting will be done with it now.

Only with your Saturday trip to the Blue Oyster Bar……
You already have your fishnets and pumps on, dont ya?
Man with that stock, barrel, and the can, what is the overall length of that?

Ill measure and get back to you. But I would say that the Socom stock gives the apparence of it beeing a lot longer than it really is.
With the LOP spacer I had 3D printed it is still shorter than a regular set up, like a carbin buffer tube and any regular style stock.
As for the suppressor, it probably adds about 3-4" compared to my previous one. But since the OPS Inc style suppressor is so much more efficient/quiet, I am more than willing to live with it. I really like a good suppressor on any gun.
(Also, I am 6´4" tall, so that also comes into play)

My first 6ARC, wanted to use a mk18 geissele rail with a 14.5”. We did a little hack job then cleaned it up and got it looking nice and FDE thanks to @LibertyArms spray skills.
I saw that pink paint on the wall behind you and immediately thought, “You’re painting you’re AR hot pink?!?!?” Granted I can’t really say much considering my wife’s build I painted purple (at her request).
Forgot to ask. How is that 6 ARC out of a 14.5”? I bet it’s pretty freaking sweet.
That’s just the base layer we put down after blasting off the anodizing. The Prison Pink really makes FDE pop
And still breaking in the barrel with factory rounds - hitting the range again tomorrow and will let you know. It’s a Rosco. Super handy build, feels awesome with the light can.
What is the recoil like? I have a 6.5CM, but never shot a 6 ARC? Is it like a 5.56 or more like a shorty .300BLK?That’s just the base layer we put down after blasting off the anodizing. The Prison Pink really makes FDE pop

Depends on the round. The 80gr felt like an air rifle and the 103s felt like another 5.56 style AR. But I’ve been shooting a 6.5cm gas gun for a while, so I’m kinda calibrated to that. It’s so much lighter and handier in the small frame.
