Bought a Fastfire II many years ago and installed on the slide of a Sig 229
After many years and hundreds of shots fired,the on off switch ,started acting up
Returned to Burris and within a day they sent me a new Fastfire III at no charge
Very happy

Serbu made an AOW pen gun years ago and registered it with ATF but never sold or advertised it and now it shows up on Canada's banned list of firearms..
Maybe ATF is sharing the registry with them
A new post on Ar15. com describes how to shoot full auto with a lightning link and a Ceiner conversion
