Review: I mounted this Burris FastFire III on my shotgun I use for turkey hunting and it has been a game changer. I love it. The dot is crisp and easy to pick up, even in bright daylight, and the automatic brightness adjustment works very well. It holds a zero perfectly, even after hundreds of rounds, and the sight picture stays clean and uncluttered. I really like the top mounted battery. No need to remove the optic and re-zero just to swap batteries. Controls are intuitive, and the build quality feels rugged enough for real use, not just the range. For the price, reliability, and performance, the FastFire III is a fantastic optic that delivers far more than expected.
Review: My only gripe with this sight is how finicky the battery cover is. It was very difficult to screw the cap on without cross threading with the battery in place but once I got it together, the sight worked great and held zero no problem on my CO2 blowback airsoft rifle. The included lens cover is awesome, it just easily snaps on and off and covers both the front and rear with a plastic/glass. I am not sure how it will hold up to impact from a BB but it is a lot better than nothing. The auto brightness setting works great while transitioning from bright to dark areas and vice versa. I have high hopes for this sight on my firearms in the future.

## Questions & Answers

**Q: Is the Picatinny mount removable if I want to use a different mount in the future? Thanks...**
A: Yes, the mounts are easily removable.I am quite happy with my Burris ff3. I actually purchased a second, of the same ff3, for my AR-15.The first, is on my 10-22.They are very small/low profile. All metal. Also, everything can be adjusted and batteries replaced, without removing the site.I am happy with both of my ff3s.

**Q: can the picatinny mount on this red dot be removed so it can be mounted on the burris fast fire mounting plate for a glock?**
A: Yes, in fact it comes in the box seperated

**Q: Will this fit the Ruger 22/45 supplied weaver mount?**
A: Yes

**Q: Just checking. Is 8 MOA preferred for closer defense target acquisition than 3 MOA?**
A: At a "typical" combat distance of 7 yards, an 8 MOA dot will cover just slightly more than a 1/2 of an inch area. A 3MOA dot will cover about 1/5 of an inch.

Rettifico recensione iniziale...dopo un paio di sedute e relativa taratura, trovo che la caratteristica tanto declamata che indica la non influenza del parallasse completamente non veritiera,semmai qualcuno leggesse questa recensione mi convinca del contrario spiegandomi cosa eventualmente io possa sbagliare nell'utilizzo.....PS 347 €uro!!!!
