An Ehanced SRP, with better mag well and sights. And a complete set of hand fitted spares that you can take with you and replace if need be. After Les made 5 proto types, one of the distributors asked Les to make 10 more guns with finer checkering, and better magwells than the prototypes. He called them Swat Prototype enhanced. They were all special builds. 10 years old, the heyday of baer. Unfired in box.
