Compact by Design. Ruthless by Nature. 

Fast. Aggressive. Relentlessly capable. Built for those who move differently.

The Specter Series from Heretic Custom Arms is a premium compact AR platform engineered for shooters who demand refined craftsmanship, dependable performance, and modern tactical capability. Built on the proven AR-15 platform, the Specter combines aggressive styling with precision-focused engineering to deliver exceptional control in a compact, maneuverable package.

Available in both 5.56 NATO, 300 Blackout, 6.5 Grendel, and 6 ARC, the Specter is offered in 10.3″ or 12.5″ barrel configurations, depending on the caliber, to suit everything from close-quarters maneuverability to precision-focused shooting sessions. Each pistol is paired with a precision free-float 10″ M-LOK® handguard, providing a stable platform for accessories while maintaining a sleek, streamlined profile.

Premium ergonomics come standard with the trusted B5 Systems P23 grip and your choice of SBPDW®, SBA3®, or SBA5® stabilizing braces for enhanced handling and shooter comfort. Finished in durable custom Cerakote (Graphite Black, FDE, OD Green, or Sniper Grey), every Specter is built to withstand demanding environments while maintaining a refined appearance worthy of the Heretic name.

At its core, the Specter features a rugged Carpenter 158 steel bolt carrier group with a black nitride finish for long-term reliability and smooth operation. Combined with a MIL-SPEC single-stage trigger and A2 compensator, the result is a dependable, hard-running platform designed for defensive applications, training, and range performance alike.
