SUBJECT: GSS 77 Accurizing the M1 and M1A Rifles for Competition

Welcome to the NRA school on accurizing the M1 and M1A rifles. During the week we will be looking at the historical development of the M1 and M14 (M1A) rifles, and learn to apply the techniques of accurizing these famous military arms.

The attached tool and material list includes the basic items which you should try to obtain for the class. Please understand that most of what you need can be shared or borrowed in a pinch, so do not panic if you can not obtain some of the items listed. If you have more than one service rifle, bring them along. There may be time to perform some modifications on more than one.

Brownells is the definitive source for gunsmithing tools when you have trouble finding what you need in the local hardware store. They are on the web or may be reached by phone at (800) 741-0015.

Finally, it is often quite warm this time of year, so you may want to bring a fan with you. You may want to bring a clamp on a crookneck shop lamp for better illumination on close-up work. We are looking forward to an enjoyable and productive experience in the classroom and the shop.

Live ammo is not permitted in the classrooms or the lab.
