The DynaComp D2 body is precision CNC machined from 416R Stainless steel. The blast baffle is precision CNC machined from H13 Tool Steel and held in place using a proprietary method. The D2 also goes through a proprietary heat treating process and many forms of quality control. The D2 is threaded 1/2"-28 for use on 223/5.56 barrels. The D2 is predrilled for pinning on 14.5" barrels for 16" OAL. It works on 14.7" barrels as well, but the OAL will be slightly longer. They also include a 3/32 hardened stainless steel dowel pin. The muzzle device must be properly timed/indexed. Then the barrel must be spot drilled to retain the pin. Then the pin gets drove in place and either welded over or fused in place using a Tig welded. The D2 is extremely effective on barrels from 7.5" all the way up to 20"+. This D2 is available with a Matte Melonite finish. The D2 is also laser engraved with the Spike's Tactical Spider brand.
