Hey gentlemen, I am wondering if any of you have had any experience with the CDI precision bottom metal for their rifle, but in particular the FN SPR rifles. I have one and am looking real hard at installing this system, it already takes the FN detachable mags, but they only hold four rounds. If anyone has any experience, or knows whether this system is worth the money, please let me know. Thanks Randy
