4.1. LOADING THE AR-10
®
MAGAZINES
20 Round Magazine: Insert each cartridge by positioning it between the lips at the top of
the magazine, with the bullet tip pointing forward, and pressing it straight down until it
snaps under the lip of the magazine. (Early AR-10 magazines have a spring-loaded
plunger in rear of the follower. To load the second round in such magazines, press the
plunger into its hole as you insert the round. Insert the remaining rounds just as you did
the first one.) Tap the rear of the magazine to seat the cartridges to the rear to reduce
binding.
10 Round Magazine: Insert the first round by the same way you inserted each round in
the 20 round magazine. To load the second round, press the plunger at the rear of the
follower into its hole as you insert the round. Insert the remaining rounds just as you did
the first one.
Load no more than 20 cartridges in the 20 round magazine (or 10 cartridges in the 10
round magazine). If the magazine is loaded tightly and the top cartridge is on the right
side of the 20 round magazine (or the left side of the 10 round magazine), you may
have loaded 21 cartridges (11 in the 10 round). Loading more than the recommended
number of cartridges will overstress the magazine lips and may cause rifle
malfunctions.
