This is the best after market rail system for this weapon system. Surefire needs to make an integrated light/rail system as they did for the Benelli M1. This rail system is the next best thing. On the down side, it cost a lot. However, you get what you pay for.
Pros: Good construction. 3 Rails
Cons: Cost. No integrated light.
This review was written in the old system and had content requirements that are different than reviews written today.
