Compact Shape Is Faster To Hit; Won't Get In The Way
Extends half an inch farther out than the "flush" factory release so
it's easier to hit and operate when you're in a hurry to change
magazines. Thin, compact shape won't poke you in the back if you
carry your rifle in a sling. Installs without gunsmithing.
