EDIT: just got it in the mail, and slapped it together for a quick pic: Will definitely be replacing the PRO and MBUS with a scope and Troy BUIS, but for right now it'll do. Hopefully I can get to the range soon and test it all out. Original message: I guess it's technically too late to second guess dud to negative feedback on this setup, but I just ordered up one of these: http://www.midwayusa.com/product/44...ith-troy-trx-free-float-handguard-flash-hider ... And wondered if any of you have had any experience with this upper. Anyone own or extensively fired one? Any pics? Tips on using this upper for a build? Anyone a fan?
