Borden Standard Machined Bolt Handle is Standard on all right and left hand Actions.

Borden “Big Knob” Handle is available as an option on all Right and Left Hand Hunting Actions. We are also offering the Borden Machined Big Knob handle 1/2 inch shorter than our standard machined handle. This makes handle approximately same length as Remington 700 handle.  once again this is only available on hunting models

Remington bolt handle is available as an option. Be advised that Remington bolt handles may have casting marks and pits. They are what we receive from Remington and we are not responsible for the quality of these handles–we only offer for those that just have to have that handle.
