Fitting the action.


Tenon fully machined, immaculate surface finish. Perfectly square and true to bore axis.


Machining the muzzle.


Fitting APA brake.


Note the radius of the bolt release protrusion on the action receiver body.

This specific action's radius happens to contact this specific chassis's action cutout, preventing even seating of barreled action. Non-drying ink verifies unwanted contact.
Radial relief must be made to the chassis for proper stress-free seating of barreled action. Even though the chassis was specifically machined for a Surgeon 591action, no two machined parts are machined equal due to normal working tolerances of both manufacturer.  We verify, remedy, and ensure proper fit of parts without bind or stress when building a rifle. Nothing is overlooked!


Barreled action Cerakoted in Armor Black. Action is prepped, sealed with putty, release agent applied, ready for bedding.


Marriage of barreled action to stock.


Initial separation, off to the mill for clean-up, clearance and relief cuts.
