WHAT WILL IT FIT – Lots of things. We anticipate this will fit about 98% of Manners PRS1, PRS1, T2A, T2A GAP, T4A, T4A TEAM and T5A stocks. If you're not sure if it will fit, you can use the hole spacing print AVAILABLE HERE and some basic common sense to figure it out. We made this as universal as possible, while still retaining weight tuning capability. These kits will come with t-nut hardware to add attachment points if your factory-installed attachment points do not line up with our mounting slots. While this can also be attached to MLOK, it DOES NOT come with MLOK hardware
