NW will be producing lowrises in the 'Bushmaster +' threading soon. They will be available from NW in matte black and chrome. I can pre-order some in gloss black and unanodized if there are enough people interested.
Since it looks like I took a bath on the highrises (what happened to all the people that said they'd buy one?), I will only be getting gloss black and unanodized low rises if I get at least 10 pre-orders - email me if you want in.
