I just received my Titanium Mag tube from Kip At Carrier Comp, and wanted to say Thank You to Kip. If you're looking for the "BEST" parts to put on your M4, I would recommend Kip's Products. They are a work of Art! The Mag tube is absolute perfection, and the finish is Spot-On, and matches the barrel of my M4 perfectly. It looks like it came from the Benelli factory because the finish is so exactly perfect, and it's very light. I can't say enough. I also bought Kips rail and it's great also. Kip's products are worth the wait IMHO. I can't wait for his handle to come out.
On a final note:
