POTD: Colt Said No To Full Auto Fun

    The picture above is basically a “Colt c*#k block”. It is a sear block that was installed by the Colt factory. This was Colt’s answer to prevent people from using DIAS (Drop In Auto Sear) or a Lightning Link back when they were plentiful and affordable prior to 1986. They even neutered the BCG so it can’t trip a full auto sear. Where is the fun in that?
