Bought this one some time ago locally for $100. The barrel was chopped at 16.5" at 70° and no crown. The previous owner had also camo painted the stock and added a large black skull to both sides. :
I fixed the muzzle, added a d&t Capco mount holding a Nikon Pro Staff, made a handguard that covers the RSB, a solid ebony cheek riser, and an ebony butt extension.
Due to not having access to the stripper clip guides on the carrier, the fixed 10 rounder was made "drop free" or "detachable" via removal of the retaining collar and spot welding the swing portion of the mag in place. Topped it off with my custom made Talon extended mag release and the system works great.
