- Perpendicular locking lugs
- Perpendicular action face

- Holes for scope bases are milled and thread milled 8 x 40 (versus drill and tap) and are in line with action bore. Thread milling results in snug threads that are concentric to the hole.

Rimrock Bolt Handle
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.
