12″ Siphon AGP 5.56 “Other” Midlength Pistol w/ GPR-9″ Rail Burnt Bronze

Description

This is an excellent product for any state where AR variant firearms are permitted; Not just New Jersey!

The SOTMFG 12″ NJ Compliant “Other” Siphon AGP 5.56 is built for shooters who want premium performance in a New Jersey compliant “Other” firearm configuration. This Legacy 2.0 forged build features a 12″ patented Siphon AGP barrel, midlength gas system, SBA3 pistol stabilizing brace, and SOT GPR-9 free-floating M-LOK rail.

At the heart of this build is the patented Siphon AGP barrel system. The 12″ nitride premium barrel is chambered in 5.56 NATO and made from 4150 CrMoV steel. It features 6-groove rifling, a 1:7 twist rate, nickel boron M4 extended feed ramps, and a tuned gas port for smooth, reliable operation.

The Siphon AGP midlength gas system is designed to deliver a smoother shooting experience than a standard short-barrel gas setup. It helps reduce harsh cycling, improves control, and supports reliable function. The nitride micro gas block and nitride 304 gas tube provide added durability and corrosion resistance.

This firearm is built on SOTMFG Legacy 2.0 forged 7075-T6 upper and lower receivers. The receivers provide a strong, precise, and dependable foundation for the entire build. The Burnt Bronze Cerakote finish adds durability, corrosion resistance, and a premium custom look.

The 11″ SOT GPR-9 free-floating M-LOK rail gives the firearm a solid, modern handguard system with excellent accessory mounting capability. The included Magpul MVG vertical grip supports the required “Other” firearm configuration and gives the shooter improved front-end control.

The bolt carrier group includes a C158 shot-peened and MPI-tested nitride bolt. It is paired with an M16 nitride carrier and a properly staked carrier key for dependable performance. The build also includes a forged charging handle, QD staked end plate, carbine buffer, SI polymer dust cover, and SOT INFERNO-2 precision muzzle brake.

This 12″ Siphon AGP 5.56 NJ “Other” is optics-ready and ships without sights or optic. It includes a rifle tactical case with 5-mag pouch and one 30-round magazine where legal. All major components are made in the USA and backed by the SOTMFG lifetime limited warranty.
