Want to suppress your SIG Sauer MCX or any standard AR-15 lower without adding overall length? SIG released its SUR300 upper receiver for shooters looking for a shortened system without having to double-up on SBR and suppressor tax stamps. The SUR300 features a pinned-and-welded suppressor that brings the overall length of the barreled assembly to 16.1 inches.
