The Vltor Bren Ten (formally the Fortis pistol) is a clone of the original 10mm Auto Bren Ten. The main differences are, according to the company, tighter tolerances and better magazines (not compatible with original Bren 10 mags).
The pistols will go on sale in May this year. Pricing will range from $1099 (Spec Ops .45 ACP model) to $1299 (Vice 10mm Auto model). Production is limited. They do not expect to produce more than 700 of the Vice model and 500 of the Spec Ops model for sale in 2010.
Defense Review also has photos of the pistol.
