Sig Sauer R516 SBR
Sig Sauer makes the R516, a gas piston operated AR platform rifle, in many configurations. We stock the R516 Patrol with the 16″ barrel on a regular basis. Sig also makes the R516 in short-barrel configurations, which require NFA paperwork. Having a short barrel allows one to add a suppressor and still have a manageable overall length. These rifles are also offered through the IOP program.
