If they view their own primary as unimportant, they can register with the other party and vote for the least-objectionable (or, more nefariously, the least-electable) candidates.
I registered Republican this year because the Dems in my primary were already locked in. So I'm technically a registered Republican even though I've never voted Republican in the general election.
He was shooting closer to 200 yards I thought.
My main AR groups better. I've got a higher-end AR with a .223 Wylde 1:7 barrel and when I shoot SMKs through it it'll group a ragged hole. But that's not the setup most people are buying and shooting.
But my gun is triple the cost of a standard AR-15, and the glass on top is even more expensive.
