Stocks
The stocks on the ADL rifle were available in wood or synthetic plastic. The wooden stock was made of American walnut with Monte Carlo styling, which has a raised cheekpiece. The synthetic stock is black and features a straight stock. The synthetic stock ADL has been renamed the SPS and is still in production. The BDL is only available with the wooden stock, and retains the distinctive Monte Carlo style. The BDL stock is also made of American walnut but features a black plastic cap on the front end of the stock. All of the stocks have checkering cut into the hand grip and fore grip, and feature swivel sling mounts.
Magazine Floor Plate
The ADL models have internal spring-loaded magazines that are only accessible from the top of the rifle. The BDL rifles feature a hinged floor plate that is located beneath the magazine. The floor plate allows you access to the internal workings of the magazine, which can be an advantage when cleaning the weapon. Both the ADL and BDL are loaded from the top.
Trigger Adjustment
The ADL rifle and its successor, the SPS, have the amount of trigger pull necessary to fire the rifle set by Remington and are not adjustable. The BDL rifle features the X-Mark Pro trigger system, which allows you to adjust the trigger pull as desired. The trigger tension is set by adjusting a small screw located on the top of the inner surface of the trigger. The advantage of the X-Mark Pro is that you can modify the trigger pull without having to disassemble the weapon.
