Name me another autorifle that can do what the AR can do? has it got a .50bmg upper? Has it got a .22lr conversion unit? has it got a folding stock, drop in trigger jobs, readily available luminous irons, ambi safety, night scope, protected irons sights, return to zero scope base, see thru scope mounts? Is it concealable, readily broken down and worked on? does it have 1/2 dozen barrel lengths and rifling twists? Does it win matches to 600 yds? Does it group sub MOA? Is it available in nearly a dozen calibers? Are lower receivers, parts groups, mags, ammo readily available? Does it take the GI load,mags, parts? is it dark, rustproofed, available with a chromed chamber and bore? is the muzzle threaded for a can or flashhider? Very few rifles have even half of the good things that come with having an AR-15, guy.
