Kratos Design Group Hera Lite Bag Rider for Magpul SL/SL-S Stocks Black. Designed to fit perfectly with the contours of the stock the Hera Lite Bag Rider fits securely on the Magpul MOE SL and SL-S Stocks and blends in perfectly with the rear of the stock. A defining feature of our bag rider is the ability to store a 1/4in bit and a Multitasker Nano optic adjustment tool giving you a method to have tools with your rifle at all times (sold separately). The Her Lite features a very aggressive texture on the bottom to ensure positive contact with the rear bag and prevent slippage. The design incorporates 2 tabs and an alloy steel bolt to securely hold the bag rider in place. One of the tabs integrates with the bottom sling mount and prevents the bag rider from moving up and down along the stock. It is held in place by a 1in bolt (provided) and requires a 3/32in wrench for installation. Weighing just .8 oz it adds over 1.5 inches of surface area to the bottom of your stock.
