SMP40 Alternate Barrel Nut Covers

3D Print Freedom 976.1KiB Released October 9, 2025, 4:24 PM

The SMP40 relies on the barrel nut cover to be perfectly oriented on the build, to ensure that the front sight is not canted. However, a builder might encounter a situation where the right orientation is between two possible positions with the stock nut cover.

If this happens, use one of these alternate nut covers to find the right position. Two are included - one that adjusts the orientation by 6 degrees, and one by 12 degrees.
