This Adjustable Bag Rider is designed for “Custom installations”. No mounting holes are supplied. Provided are 2 qty 1/4-28 × 1/2” long button head bolts (the heads fit into M-lok slots). If you need assistance with a custom installation -use the contact button below in Red - we’ve seen or done many different installs and some are listed on the “Installs” page. Most likely modifications will be needed to the stock to allow the rear dowel and/or stud to pass through your stock to get the ABR away from the grip and have 1.75”+ empty space between the grip to the front of the ABR. Contact us if you want our guy to quickly install an ABR its $100 + $35 return shipping (with Insurance) and a 2 week turnaround - he supplies the ABR. Quickly converts bag to original setup if the ABR is removed.
