Look around and check out the different options. It is too easy to find something early on and think this is it. All options mentioned are viable. Mark does excellent work as does George. Let them know what you want and they will that route. look at LaRue and his add ons, he does excellent work and by all means contact AMU and tell them what you want and how you want it.
The weapon jbour is talking about is another very viable choice, but it is still in prototype unless it has advanced some.
As an aside, the M110 SASS is a disaster!
