KTW SPR Bull Barrel
The image shows the lens attached to the newly released M70 NEW BLACK SHADOW.
The BS is a semi-bull barrel, but it is significantly different from the SPR's full bull barrel, which has a muzzle diameter of 1 inch (25.4 mm). When replacing it with an SPR barrel, the position of the set screw holes on the receiver may be slightly different, so some processing is required.
