    SP4 BCG

    I have been waiting to get my hands on one of these for a long time. I was very surprised to see that they were now being mass produced and even have several color choices. I jumped on this purchase faster than any other. 150 rounds in with my new build and I am already sold. The slick texture can only be described as rubbing clp on a mirror. It’s that nice. The function was impeccable. When it came to cleaning, I have never seen a bcg come fully clean with just a wipe down from a paper towel (and I work in an armory). This will be the only type of bcg I buy for my new builds in the future. The shipping was also very fast, but that’s just a bonus.
