V Seven Ejection Port Door .308 Grade 2 Titanium Raw Finish Silver. The door features a precision machined .308 hole with a radiused outside contour that gives the look of a hand crafted precision instrument. The edges of this ejection port door are burnished and stippled to a sharp finish for a clean look. The V-Seven Innovations Grade 2 Titanium Ejection Port Door is designed with an aggressive "stepped" look the same as seen on high end handgun ejection ports. The Grade 2 Titanium material will not be subject to the rigors of carbine barrels and will give a positive seal similar to that found in aerospace applications.
