WELCOME TO THE NRA GUNSMITHING SCHOOL FOR ADVANCED RIFLE BARRELING!
Attached is the required tool list for this school. Please arrange to have
these tools with you when you arrive for your class. Space is provided to
lock up your equipment, so you need to bring a padlock or two with you.
Live ammo is not permitted in the classrooms or the lab.

Depth micrometer set 0-2”
Thickness gauge, tapered leaf

A few assorted open end wrenches (7/16, 9/16, 1/2, 5/8,) or large adjustable wrench
Some live ammo for the caliber of your rifle
Safety glasses with side shield
A receiver mandrel and bolt mandrel for your receiver
Allen wrench set to 3/8”
Needle file set
Small course India stone for shaping firing pins
5 – Shop rags
2” paint brush
Emery strips, 1/2” wide, at least 3’ feet long (240, 320, & 400 grit)
OPTIONAL TOOLS (BRING IF YOU HAVE THEM)
Carbide tools bits ( 3/8” right and left cutting )
Action wrenches for your actions
Magnetic base dial indicator 0-1
You should bring at least one pre-turned barrel blank (select a contour
that you want) and a bolt-action receiver. Just in case you finish
before the five-day class is over you may wish to bring another barrel
and action to get started on. Please bring only bolt-action receivers
We will have you preparing the actions by facing off the front of the
action to square it up as well as lapping the locking lugs and possibly
welding and re-drilling the firing pin hole. We will then have you
thread, chamber, headspace and crown your barrel. There should be
sufficient time to polish and blue your barreled action as well.
The school has a small selection of the most common caliber reamers;
however we strongly suggest you check ahead of time (4 weeks minimum)
what is here. Often our students simply wish to use their own reamer
and headspace gauges in order to have identical chambers in several firearms.
Please call is you have any questions.
We look forward to seeing you.
