Disclaimer
Due to the aluminum-on-aluminum interface between the stock adapter and the SCAR’s rear back plate, a small amount of movement or “wiggle” may be present when properly installed. This is normal and does not affect performance or durability. For users who prefer a tighter fit, applying Teflon tape to the mating surfaces is a popular solution to reduce play and ease installation.
Note: All NFA rules apply.
