The Loading Block by Long Shot Precision is designed to fit the Desert Tech rifles when using the ABR. due to the different frame sizes - the ABR could be underneath the magazine on the smaller models (making it a single feed). A loading block instead of a magazine is recommended as it provides additional spacing for the adjustment hand. As you can see in the additional pics the magazine interferes with easy access to the thumb wheel.
