If you read any of the astigmatism threads, I've been looking at prism scopes for my AR build. I'm taking a chance on this scope because I haven't tried it yet. But it appears to be the size of a red dot, weighs about 8 ounces with the mount, and is on sale for 50% off at the below web site. At that discount, I figure I can try it out and worst case, if I don't like it, sell it on eBay for no loss. Retail $300. Sale price $150.

Progressives are the most open minded, tolerant, and inclusive people on the planet, as long as you agree with everything they say, and do exactly as you're told.
