Key components and field use
The SigM400 upper is known for durability in service-style AR platforms; pairing it to an Aero Precision lower gives a solid foundation. The Midwest Industries quad rail provides four-sided mounting real estate for lights, lasers, and vertical grips, enabling mission-driven setups. The SB Tactical PDW brace converts the pistol into a more compact, controllable package for close-quarters drills and vehicle work while remaining maneuverable for general range use.
Fit and buyer considerations
Because this is used inventory (model listed as Various under the Aero Precision brand), inspect the bore, gas system, rail mounting, and brace condition before purchase. Caliber is not specified on the listing, so verify chambering prior to ammunition purchase or range trips. The $890.99 price reflects the combination of quality components and the “older inventory willing to take offers” note — factor negotiation into your buying plan. View product details and pricing
