| Currently have a TA31H w/5.56 BDC and I'm getting ready to build a 6.8 upper. Trijicon stated that there is not much difference between the 5.56 and the 6.8 BDC for the first 300 meters. Anyone used a 5.56 BDC on a 6.8 or have knowledge on it? Don't want to buy a new ACOG if mine will work. Thanks. |
