Product description
“Black and Tan” 13.7″ 5.56 NATO Home Defense AR Pistol Dream Build
The “Black and Tan” September Dream Build is a compact 5.56 NATO AR pistol package designed around fast handling, practical controls, and a versatile sighting system. Its 13.7-inch Ballistic Advantage barrel and 12-inch AT3 SPEAR M-LOK handguard keep the front end compact while providing useful mounting space for the included Streamlight weapon light.
A Wilson Combat forged upper receiver houses a Faxon lightweight bolt carrier group and Radian Raptor ambidextrous charging handle. The upper is completed with a Dead Air Keymount Micro Brake, AT3 low-profile gas block, mid-length gas tube, Strike Industries dust cover, and AT3 forward assist.
The lower starts with an AT3 AT-15 forged receiver and adds an AT3 Pro-Builder lower parts kit, AT3 4.5-pound two-stage trigger, and Radian Talon ambidextrous safety selector. An SBA3X pistol brace, FAB Defense ergonomic grip, adjustable Odin Works buffer, flat-wire spring, and QD end plate complete the rear of the build.
The SIG SAUER ROMEO5 Gen II and JULIET3 magnifier provide a flexible 1x/3x sighting combination. The package also includes an Edgar Sherman Design two-point sling, Streamlight ProTac Railmount 2L, two Magpul 30-round PMAGs, and a Magpul MAGLINK coupler.
