I recently finished this pair of BR99’s destined for different parts of the country. The top one has a Cerakoted Titanium finish forend with coupled 5 shot magazines, tactical bolt knob, oversize magazine release and so on plus a healthy weight of Chromite in the butt to bring the balance back
The bottom one is finished in Flat Dark Earth Cerakote, has the breaching choke and Magpul AFG and both have relieved magazine wells and some polishing hear and there. One thing I have noticed is not all BR99 magazines are equal, in fact no two BR99’s seem to be the same with very subtle manufacturing differences from build to build. I learnt a while ago not to assume that a part destined to fit a BR99 will actually fit without some slight/medium/drastic modifications along the way. Another point is they do tend to shake around a bit so screws have a tendency to come loose unless loctited in place.
