This kit includes three of Fortis’s most popular items packaged together for a single price: the Lightweight Enhanced (LE) castle nut and end plate system, the SLS Fifty ambi safety selector, and an enhanced mag release button. The LE castle nut/end plate combine to virtually eliminate the risk of the nut ever backing out. The SLS Fifty selector is engineered using a patent-pending RidgeKey locking mechanism that secures the levers to the selector core in lieu of standard sockets/Torx screws. The mag release button installs in seconds for a near-instantaneous upgrade for your rifle’s lower.
