Black Rifle PRS Slim Bag and Flat Frame (MLOK) - Coyote
The PRS Slim Bag and M-LOK Flat Frame are designed for stabilising your shooting platform. Whether you're shooting from a tank trap, fence, off a truck or a pile of rocks, the Slim Bag will keep you on target. Alternatively remove the bag and you have a wide, flat base that's ideal for benchrest style shooting or thorowing onto an existing bag.
The PRS Slim Bag is made by the UK's top shooting bag manufacturer and is filled with mid-weight HDPE pellets. If you want your bag lighter (or heavier), the integrated fill spout makes changing fillings easy.
The Flat Frame will attach to any M-LOK handguard with 1.5 slots free.
Designed, tested and manufactured in Great Britain by Black Rifle Limited and is warranted for life.
