the seller is southernordnancesales
he has 2 different styles the one i got has grooves in it with o rings on the handle which you can remove leaving a smooth grooved handle or you can also get one that is Knurled.
you can also search savage tactical bolt handle on Ebay and you should find him, he is located in Fort Lauderdale Florida shipping took less than 2 weeks.
i got the longer one
Update on 2/2/2013: We ran out of the 2" knobs until Wednesday or Thursday of this coming week. If you purchase this item between Feb 2 and Feb 8 you will receive it with the short 1.65" knob. We will send you the 2" FREE OF CHARGE and you can keep the short one compliments of Southern Ordnance with the purchase of your Savage Tactical Handle. This offer will only be valid until we get our tactical knobs back from the anodizing shop.
you have to look him up on the Ebay US site, look and ye will find.
I did that and used the search facility but nothing came up. I guess I'm technologically challenged!!
