Good review and well thought out selection of parts. The ONLY thing I would change would be the LMT 2 stage trigger.

Having attended numerous Patrol Carbine, SWAT Carbine / Rifle, and Civilian Tactical Carbine courses over the years......In these classes I notice a HIGH failure rate of 2 stage and match triggers. Experience has taught me to stick with the standard factory trigger. Just my .02, your milage may vary.

Denny, dammit, STOP it!!

All great. What was the best group you shot when testing this barrel for accuracy? and which load? George

Excellent post, Denny.

It's refreshing to see not just a list of components, but also a rationale for their selection.

Denny, what does "bagged in good and tight" mean? Sandbags bracing the rifle? under the stock as well?

I guess it comes in handy to have all those parts available for a build, I imagine.

I love it whan a plan comes together!

Great carbine!

That is about as much as you will ever really need right there. The only thing I would change is the Eotech (I'm an Aimpoint man).

Nice gun, I'm jealous!

But where did you get the barrel? I did a google search for Rock Blank barrels, but didn't come up with anything that would take me to a manufacturer or distributor.

I like the barrel profile. I've been kicking around having a 6721 barrel trimmed down to a similar thickness.

I also like the closed Phantom. The ones with teeth catch on damn near everything. I don't think the looks of the teeth justify the amount of snags, but then again, looks never make up for much. When looks do matter, God made alcohol for those single guys.

Nice light weight rail choice. Do you loctite the DD on your personal builds?

On the fixed front sight issue, I'm glad to see there is someone aside from myself who feels that stronger and simpler is better.

I like the PRI biglatch, its small enough to not grab on things, but made well enough to make a difference.

I'm a MIAD fan, but grips are an individual choice, so there isn't much room for comment there. Same with the KNS pins, I like the look, but I'll hold off until I have a pin that enjoys wandering. If I had a set, I would probably use them, but it just isn't anything I can justify going out of my way for.

I love the feel of the LMT 2 stage, but I wouldn't put my own butt on the line with one. I'll stick to the single stage gritty, ugly nasty trigger. I just don't have the faith in them that I need to use one for duty. One of these days I'll run one on my Mule/ T&E/ Training weapon and see how it holds up over time and extended round count.

I'm also an Eotech fan, so I'm right along with you on that choice as well.

Out of everything, I like the barrel most. Mostly because I have already been kicking around the same thing. Run some classes or extended drills and update the thread. I know someone who doesn't understand will come along and comment about the increased weight of your chosen barrel, but those are people who are missing the point anyway.

Thanks for the thread, its a good one.

The barrels have a proper F height front sight and are parked under the FSB.

The barrels are heat stress releaved, proof fired and MPI tested.

I designed this barrel for extreme use and heavy enough for a silencer with minimal POI shift.

Here is a pic of the barrel stripped.


Barrel Markings

The barrel is called the Operator. We are currently out of stock but another 50 are in production.


Thanks, I'm definitely interested. If you don't mind could you drop me a note when you get some more in stock?

Very nice Denny!

I really like that barrel configuration. I think it will go will with your GT lowers

The only thing I would change would be the 2 stage trigger. I'm a standard FCG guy but to each his own
Link Posted: 1/8/2006 12:11:03 PM EST
Hey Denny, How come you did not use your own lower? Conflict of interest? Wouldn't a CMT lower fit better because it came from the same company? Also could you put me on your waiting list for your next operater batch coming in ? Carlos.

I hate you Denny!

Very nice, Denny.

Any chance we will ever see a Mike Rock barrel in a superlite configuration?

Mid length kicks ass! Nice weapon.

Let's see some pics with a lower profile gas block [LaRue] and a rifle length rail.

ETA: Sorry about "dee". I've been drinking.

damn fine looking rifle.

Looks good Denny! I like the profile on that thing, I'll be saving my pennies.
Link Posted: 1/8/2006 7:30:53 PM EST
Wow, Denny yours look awesome and always an inspiration for my build.

Here's my Operator build version, components not listed are same as yours:

Phoenix FS
LaRue 9.0 rails
TD VFG and Magpul ladder rail protectors
KAC 300 m BUIS
Colt M4 upper, 6721 lower and CH
Wolff extractor spring
Norgon ambi mag catch
Stag Arms ambi selector
Magpul MIAD grip
Vltor club foot Modstock kit with rubber buttpad
BlueForce IDF style two point sling
Aimpoint M2 with KAC mount but will replace it with LaRue when available

My furniture and sling colors are dark earth, coyote brown and tan. All parts were bought from the EE except for the receivers.

Future planned improvements are SureFire tac light and EOtech.

My Operator is only slightly heavier than my LMT 16" M4gery but still very easy to move around. It's lighter than my stock 6721 before I modified it.

It took me about nine months to finish my project and it was worth it.

I'm very satisfied with my barrel and I'll post pics of my Operator version soon.

Just found a use for my tax return
Link Posted: 1/9/2006 2:10:30 AM EST
I've asked Denny to post or paste my pic of my Operator with:

Larue 9in
Larue gasblock
CMT upper
Troy BUIS (front still on its way)
Noveske lower (borrowed from my SPR N4)
LMT Sopmod stock
RRA 2-stage
Trijicon TA31f

The optic will be changed to Eotech when the LT mount arrives. Trigger is being reviewed.

Nice gun! I would've gone with an aimpoint for a CQB rifle, i've always thought that the EOTECH might enjoy a little extra precision for long shots while i like the AP for simple rugged operation in close.

Excellent Denny !

Love the weight and contour of the barrel - Perfect !

Sweet rifle Denny and I don't know how I missed it!! I've been eyeing a mid-length setup for awhile and you've got my mind ticking...
Link Posted: 4/2/2006 6:36:40 AM EST
Is that a chromed or stainless barrel extension Denny?thanks
Link Posted: 4/2/2006 6:55:32 AM EST
Great build! I have been trying to decide between a middy with 9.0 and fixed front or 12.0 with flip up front. Is there much weight penalty for the 12.0 vs. 9.0? Which balances better?
