The main benefit of GCA membership is receiving the GCA Journal . Four issues per year are published:  Spring (March), Summer (June), Fall (September) and Winter (December). Each full-color issue contains articles from some of the most knowledgeable people alive today about John Garand’s superb M1 rifle, complete with photographs. If you want to learn all you can about the M1, you will enjoy the GCA Journal. Also, the GCA is affiliated with the Civilian Marksmanship Program (CMP). Membership in GCA fulfills one of CMP’s requirements to make a purchase.
You can join online with a credit card (Get your Membership).  Or, you can submit a membership application by mail and pay by check/money order.  (Membership Form).  There is a basic, common sense member conduct and fraud policy and members must agree to abide by this policy.
New or renewing members will receive a receipt for membership dues and a wallet-size membership card. New members will also receive a packet containing their first issue of the GCA Journal, a welcome letter and a data sheet for the M1.  All members are mailed the GCA Journal each quarter as new issues are published.
GCA membership costs $25 per year if you live in the U.S. If you live outside the U.S., the dues are $40 due to higher postage costs.
Starting in May 2013, new memberships expire 12 months from when a new member joins. Example: Join on May 15; membership expires on June 1 next year. The expiration date is plainly printed on the membership card. (Previously, all memberships expired on Sept. 1.)
You will receive an official GCA membership card that will act as proof of your GCA membership status. IF you indicated “yes” on your membership application to release your information to Civilian Marksmanship Program, your information will be transmitted to CMP as part of a routine update that GCA provides to CMP.  There is processing time on both sides of the data transfer.
A reminder notice will be mailed to you when it is time to renew.  You can renew your membership online (Membership Page), or by mail or fax.  Download the latest renewal form here: Dues Renewal Form
Membership renewal is accepted at any time. Renewing members will always receive a receipt for their membership and a new membership card.  Your membership, and your subscription to the GCA Journal, will run for 12 months from when your renewal was received and processed.  (Previously, all memberships expired on Sept. 1)  If the renewal was received so late that GCA Journal issues have been missed, they can be purchased as back issues for $5 each, subject to availability.
Periodically the GCA holds a National Convention, which rotates around the United States. At these events, members get to enjoy the camaraderie of other collectors and see other parts of the country.  Conventions are sometimes held in conjunction with major gun shows.  Some Conventions feature special shooting matches.  Several Conventions have been held at historic Springfield Armory.  Whatever the venue, every effort is made to offer a Convention program that is entertaining, educational, and provides an opportunity for Garand enthusiasts to get together.

Additionally, GCA sponsors entry fees for members who participate in certain events at the National Matches held each year at Camp Perry, Ohio.  For shooters, these events are ideal for using your M1 to its fullest.

Many back issues are still available.  They can be ordered online Back Issues or by mail with an order form The Best of the GCA Journal series of books  was created due to demand for back issues that are out of print.  Each book contains three years or 12 issues.  These books are a convenient and affordable way to own all the good information published by GCA over the years.  Books 1 through 5 are currently available, with a $15 discount when you purchase all 5.
