We don’t see that many custom builds utilizing the Colt 6720 so thought I would post a pic up of one we did for a customer.

LaRue is still one of my favorite rails on the market. Nice looking build… Must have been a special customer as I know how much you love shaving FSB’s. ![]()
We bought some air cutting tools and a bench grinder so it is an easy thing for us to do now.
Cost for a shaved FSB is $65.

Hell yea thats pretty sweet nice work
Thanks much.

Very nice looking build, Grant.
And you practiced at it for a while before hacking customers’ stuff up, right? ![]()
Douchebag or not, ML puts out the best quad rails on the market, IMHO. Nice build.
I had done them before, but it was a slow process so I really tried to NOT do them. With the purchase of better tools, I can do it much faster now.

Awesome
I agonized on my last upper on whether to get a 6920 or a 6720, deciding to go with the 6920 only because more potential students will have something comparable or lighter, and I wanted the upper to be the least “trick” as I could stand.
Ok, I pondered it for about 10 minutes, but that’s about as close as I get to agonizing over a purchase.
Silly question: are the 6720’s going to be available with the Centurion 12.0 FSP rail?
I think one of those would be ‘THE M4C Carbine’.
…
I’m very interested in a 6720 with a 12.0 FSP rail. Either the Centurion or the Daniel Defense Lite. The DD M4 would be ok as well, but I like the continuous top rail that the Centurion and DD Lite rails offer.
Maybe, but at this time we do not stock that rail.

We do have DD rails in stock.

Yeah… I like the rail dimensions on Doucher’s rails the best…
I still haven’t been able to buy his alloy yet though.
Just picked this up at my local gun store.




came with 2 p-mags, rail covers, vertical grip, and qd sling attachment.
I checked this afternoon and I don’t see the DD Lite 12.0 FSP on the DD product page. I thought I recall that the DD Lite 12.0 FSP used to be offered as a rail option for the 6920 on your website. The M4 12.0 FSP is also listed as Out-of-Stock.
I’m probably a few months from pulling the trigger on this, but when I am ready, what is the easiest way to go about getting a DD 12.0 FSP rail installed on a 6720? I’d prefer either the Omega X 12.0 FSP or Lite 12.0 FSP. Is it easier/possible for you to special order a rail and install? Or is it easier for me to purchase a rail and have it shipped to you for installation?
Thanks!
I think we have the LR 12.0 FSP in stock.
