This is my old patrol rifle. COLT LE6920 with 16” barrel and carbine gas. I’ve planned on selling it, but I just don’t like selling rifles. It has the LE/MIL restricted markings. I’m definitely not interested in an MK18 clone. I’d hope for something at least 13.7” I’m opening to cutting down the barrel or swapping it.. or even converting to piston. Barrel probably has less than 1k rounds through it. I’m really just looking for a cool clone look perhaps with one of the KAS RIS rails. It’s just so boring. I’ve got a 14.5” piston that is awesome. Also open to maybe using a different caliber? It’s purely the look I’d be interested in.
Could I make this into a cool “clone”?

I hate the restricted lowers. Infringement on display. Might as well say “Sorry peasants, you’re subjects and can’t be trusted.”. I’d keep it in its factory configuration as a reminder of how the people are truly viewed.
Lol!! I won’t respond to that.. but we are on the same page. I found a “look” I liked. It’s not really a clone of anything, but it will be cool looking especially with the little “restricted” touch. I’d never seen the Daniel Defense RIS III, so I think I’m going in that direction.
With my snarky comment out of the way, a Block 2 build is peak Colt imho.
Good luck with your build.

I definitely like them, but anything under 12” 556 is just not enjoyable for me to shoot.
While not a clone AT ALL, I came up with a plan that involves using my Colt restricted receiver set into the 14.5” piston setup and leaves the Vltor MUR and ADM UIC receivers for a 13.9” (likely) 6.5 Grendel build.
The biggest change will be that I’m going to cerakote the receivers (after complete disassembly) and the Geissele 13.5” MK4 in E140 Foliage cerakote. Going with an ODG UBR Gen2. I’m going to add an FCD ambi mag release that matches the Seekins bolt catch to make it a little closer to ambi with a Radian Raptor / Talon. I’m going to stick with the Geissele SSP trigger. I’ll get some pics up as soon as I get things cerakoted and can start assembly. Should be a fun use for that set that frees up the other upper/lower for a SBR piston 6.5 Grendel with the Daniel Defense RIS III 12.5” rail.
Crap… I hadn’t seen these.. if I were to put the Daniel Defense RIS III on this I’d be pretty close (I know they used RIS II, but no way am I going back to a quad rail on a rifle I’d actually use). My Colt upper has the keyhole markings if I remember correctly.
If I did that I’d either need a longer barrel to work with the 13.5” Geissele MK4 or another shorter rail. I though the Geissele MK4 was pricey until I saw that the Daniel Defense RIS III is $440.
Geissele Mk16 Rail and chop to 14.5, for a URGI. Done.
So I made some progress. More than I should have. This far the build is
Colt “restricted” upper and lower
Daniel Defense 12.5” RIS III rail
*these will be cerakoted with E140*
Magpul UBR in OD green
Magpul K2+ in OD green
Radian Raptor/Talon
FCD ambi mag release
Geissele SDE trigger
Superlative Arms piston system MLGS
POF roller cam pin
Seekins bolt catch
Craddock RTR 13.9” 6.5 Grendel
HUXWRX 762 flash hider
The idea that this sort of kind of will be sort of like a Block II but a different caliber
I was also hoping to use this in some of those run and gun events where targets range from 20 - 600 yards.
I’m thinking a MPVO with a 12 O clock RDS. I’ve never done this combo before.
I’m thinking an ADM Delta cantilever mount with a diving board mount. I was leaning towards the Steiner T6XI 2.5-15 with a 50mm objective or a Steiner T6XI 3-18 with a 56mm objective. Although I’d prefer a NF 4-16, I can get the Steiners for around $1350-$1400. I’m leaning towards the 2.5-15 due to weight and trying to keep the Trijicon SRO as reasonably close to bore as possible although I plan to zero it for 50 yards.
Thoughts?
I plan to cerakote over the weekend assuming the rail arrives on time. I’ll post some pics when I’m done. This is my first time cerakoting receivers and rail as I’m a perfectionist and the results must be perfect.
I haven’t ordered the barrel yet as they were OOS last I checked and I have a cumulative “bill” due around beginning of June of a little over 16k. I’m not being very responsible.

If I had a SOCOM barrel I would be tempted. Fortunately I’ve only got a nearly new Colt HBAR left over
So… I wanted something darker than the Elite Jungle so I added some Elite Blackout. I’ll spare you the details, but the color didn’t come out as I’d hoped. I’ll get some pics in the light when I get it assembled. It’s like a grey/blue/green and crazy glossy. It feels like glass. The coverage was perfect thankfully. The Craddock 13.9” 6.5 Grendel barrel is on the way along with the last few “gun parts”. Optics will have to wait a while.
Barrel isn’t here yet, but everything else is installed. The rail obviously isn’t installed, but I wanted to get a feel for how it would look. It’s a 12.5” Daniel Defense RIS III and I’ve got the 13.9” barrel on the way.
I was concerned that the FCD mag release wouldn’t drop the mag 100% of the time since it doesn’t seem to have much movement, but it’s 100% even with an empty mag. Forgive the smudges. It’s a very high gloss finish.

One thing I learned the hard way with coatings like Cerakote, or any thick application to the lower receiver, was that build-up inside the mag catch slot prevented mag release when using a loaded magazine sometimes.
I had to file down some of my mag catch slots to get them to function, so it’s something I added to my personal checklist.

I think I read a thread where you mentioned that.. which resulted in me covering up the inner portions of the upper and lower and areas where clearance may be tight... so thank you for that. The E series also appears to go on much thinner
So… the Superlative Arms piston system wouldn’t fit inside the RIS III rail. I was able to get an aero low profile adjustable gas block to fit fortunately. Unfortunately I removed the gas rings from the JP Bolt while using it with the piston system so I’m waiting on replacement sprinco gas rings. I went with a chrome Microbest carrier. I think I’m leaning towards just doing the Steiner T6XI 2.5-15x and no red dot. I’ve got 3 other rifles with either an RDS or a LPVO with 1x.
I finally replaced the Noveske 10.5 with a Colt 10.3 on my Block II CQBR. And it doesn't run. Short strokes. I bought the barrel at the EE thinking it was a factory 10.3, but now I'm wondering whether it was chopped down from a 14.5 or 16. My Noveske barrel ran nearly everything I threw at it, so I was pretty disappointed.

Does it have any markings on it? Colt cage code, etc.
Mine runs fine so far either way. Bought it from a GB seller that always has colt crap laying around. Just ran it suppressed a week ago maybe
Crane Spec Gas Port .070
Mil-Spec Buffer Spring
H2 Buffer
That combo is about as proven as it gets, so start trying to sort out where things went wrong.
What do you think may have happened? I planned to cut down my 16” HBAR carbine don’t barrel to 13.9” and set that up with a Superlative Arms piston system as a run and gun rifle for my girl…
It shot my 77 grain handloads at 0.8 MOA consistently. Do you think there was a mistake while cutting the barrel? Or?
Aren’t all the Colt carbine length gas ports the same size?
It’s really hard to get a good pic of the rifle. It’s got a high gloss finish and shows fingerprints like nothing I’ve ever seen. Here you can better see the green compared to the black on the 18” Grendel. I got a Magpul bipod mounted to the KDG QD MLOK as a spare bipod for the 14.5” AR, 13” SCAR, and 13.9” Grendel to share since I don’t want a bipod on any of them full time. The guns with full time bipods get Atlas V8’s. Gas rings came today. I’ll probably mount one of my other scopes to it and take it to the range to tune and function check this weekend.
