Re: Eotech EXPS3-0 or Burris Fastfire II AR F3 mount
I own both a Fastfire II and two EOTechs - a 512 and an EXPS2-2.
As far as the Eotechs, i like the two dots - the center represents 50 and 200 yards, the lower dot 500 yards. Bottom of the 65MOA circle represents 7 yards.
If I had it to do over again with the Fastfire, I would spend the extra money and go with the Leupold Deltapoint - it's brighter (it still adjusts automatically like the Fastfire). It's probably a personal thing, but for speed, I like bright. It seems like I have to hunt for the dot in the Fastfire.
That being said, I think the Fastfire is a tremendous bargain, and I like the variety of mounts that are offered individually. The ARF3 mount works a lot better than the picatinny wing mount, also by Burris. The ARF3 is just slightly wider, so the optic can be inserted and removed without a third hand. Since the original gasket that makes the Fastfire waterproof can't be used with the picatinny wing protector, Burris told me that it ceases to be wateroproof. A little difficult to describe, but the switch on the side is exposed on the bottom unless the full gasket is used. I believe the full gasket can be used with the ARF3.
