I have the Tapco Stock you asked about. I like it a lot. It works quite well. The mags are great. I have 3 of the 20 round ones. I have had no feed issues of any kind. I have been using it for several years. The top piece that the gas tube fits in looks nice. But the rail is worthless. It moves too much to be accurate beyond anything close. I mean you could defend yourself with a red dot on one. But you wont win any competitions with it.
Romans 1:16 I am not ashamed of the gospel, because it is the power of God for the salvation of everyone who believes: first for the Jew, then for the Gentile.
