How do the Low-tube and LEO adapters accept stocks without using that indexing dimple?
We had to design a specialized claw type indexing plate, which we supply with each Low-tube and LEO adapter to use in place of the indexing plate normally supplied with standard AR-15 stocks. The photo shows the claw type indexing plate alongside the back of a Low-tube adapter, and the photo on the right shows the claw type indexing plate installed.
