There are a wide variety of AR-15 magazines being made today. Long-time firearm accessory manufacturer TAPCO makes their own polymer AR-15 magazine that they believe meets the needs of many shooters.
Designed after interviewing military members, law enforcement officers, and citizen enthusiasts, the TAPCO AR-15 magazines are solidly built, reasonably priced, have a number of nice design features, and are available in four colors.
Overall construction of the magazine feels excellent. The body of the magazine feels very strong. In fact, as compared to virtually all other polymer AR-15 magazines, the TAPCO seems the most solid. The follower slides smoothly through the magazine. There are no noises from the follower or spring when the magazine is shaken (loaded or unloaded.)
The body of the magazine has a wide, waffle-style pattern for obtaining a good grip.
