This is an as new un-modified Navy style HK lower. To use this lower on a semi auto, you need to do a simple modification often called "Clipped and Pinned. Which in basically opening up the gap between the front pin hole tabs. The front pin hole are often filled by gluing in the cut off pins which is purely cosmetic. Also an even easier modification is just to cut the pin hole tabs off. Since semi auto lowers do not use the front pin hole tabs, they are not needed. Instead, semi-auto lower will have the front of the lower resting on a protrusion on the back of the magazine well.
All NFA rules apply. It is legal to own this lower but it is not legal to modify this lower to make a machine gun unless you are a licensed manufacturer FFL type 7 with a S.O.T class 2.
