The ELR Wedge was designed by Robert at Alamo Precision Rifles. It’s an ingenious design that utilizes a two sided wedge to allow you a wide range of heights underneath the stock. From 2″ all the way up to 8″ this bag will carry you across any course with elevation or angle changes. The bag is available with our standard or light/firm fill. Both fills lock together very well and are extremely stable. The light fill is a little less than half the weight of the standard fill which is 90 oz.
