Here's how it goes:
Bolt, Lever, and Pump Action-
There's no way possible to get an AR thread in here, but somehow it happens.
Semi-automatics -
Preferred location of all AR15 vs. Mini14 threads. On occasion, someone gets in a post about another type of semiautomatic rifle such as 10-22, FAL, BAR and so-on but they quickly get lost. Somehow AR pistols are included in this group. A good place for caliber wars and over priced triggers.
As Mini14 owners become frustrated with the inability to make dime sized groups with the rifle, they migrate into the world of $600 Mil-spec ARs. After all, they heard for years that any bargain-bin AR can outshoot a Mini. The disenfranchised Mini owners turned Mil-spec AR group soon find themselves locked in an epic battle with the High-End ARs.
Some enter the fray with the disenfranchised-Mini-owners-turned-Mil-Spec-AR group as Mil-Spec-owners, bypassing the Mini14 stage all together. They all keep upgrading their ARs while squandering their collective fortunes. They spend much of their time waiting on UPS and FedeX trucks and checking tracking numbers while pretending to go outside and smoke to cover their activities.
