The statement in the subject line certainly applies to OLYMPIC style shooting, which, while the main emphasis of this board, is very much a minority of US target shooting.
There will be almost NO foreign made rifles at the conventional high power and service rifle events at Camp Perry, which is likely the biggest nationals in the country and will be roughly 10 times more well attended than any ISSF event in the US. 90% of those guns will be black AR-15 variants.
In High Power, Benchrest, Silly-wet, Bullseye pistol and maybe a few other games, US guns dominate (many custom made). In IPSC/IDPA/ practical pistol, BPCR, SASS and other target events, US gun companies are very well represented...
While I guess it is natural that we who specialize in one form of competition tend to look down on the other games, we must not forget that all TARGET SHOOTING events and their participants and equipment must be portrayed publicly as just as legitimate as ours.
