I love the look of your 10" in the bottom of the pic!
Looks like mine, cept a little shorter barrel/mag and diff front grip:
They are making me two barrels: First one will be a 12.5" with 3.5" chamber with no sights for my current Rem 870 Super Mag (evil flash hider on the end, +1 extention, will be same as 14" barrel at the end), and eventually a 6.5" 3.5" chambered barrel for my newly imported restricted Rem 870 Super Mag receiver. The 6.5" will have a custom barrel retaining ring and setup, custom 870 action bars, custom 870 mag tube, HK MP5K PDW front pistol grip (or fold down pistol grip, havn't decided yet). I have a machine shop that's making up a sweeeet mount for my 11.5" AR15, and I've got them to make up a very nice smooth AR15 rear pistol grip adapter. As soon as the barrels get here, lots of projects to try out.
Dlask will make anything you want. Because they are already making the new 870 barrels, it will be nothing for them to cut a blank down to 6.5", stamp/mark it 6.5", and off it goes for finishing.
I'm not really sure what the delay is, but I heard recently things are looking better.
