    Why would I want demand for these to go up up? I need to get at least one for every rifle now.

    Hard Chrome BCG

    Posted by JM on December 12, 2023

    Purchased this a few weeks ago on sale as I am converting to the hard chrome in all my weapons. Fit and finish are excellent. Cleaning is much easier, just like the original Colt carrier in my old SP1. Will continue to purchase these as needed.
