Product Description

The SRD556 is an Inconel 718 direct thread suppressor. Inconel 718, a nickel alloy stainless steel, provides the highest level of durability, particularly with short-barreled hosts using supersonic ammunition. The 1/2x28tpi threads match the vast majority of modern rifles in .223/5.56mm on the market today. The rear mount has wrench flats to torque the suppressor to the barrel. These wrench flats can be used as a location to "pin and weld" the suppressor to make a shorter barrel over 16" in total length.

Features

  • Inconel 718 Provides greater durability for short-barreled and high-round count applications.
  • Taper-Lok While compatible with all traditional 90-degree shouldered barrels, when using SIG SAUER tapered shouldered barrels, this optimizes alignment, improving accuracy and greatly reducing point-of-impact (POI) shift.
  • Wrench Flats Easy removal, even with heavy carbon build-up. The wrench will automatically disengage the secondary retention latch with no ratchet teeth to wear out.

Specifications

  • Caliber 5.56 NATO
  • Diameter 1.625 in (41 mm)
  • Overall Length 6.4 in (163 mm)
  • Threads 1/2 in - 28 tpi
  • Weight 14.5 oz (411 g)
  • Material Inconel 718 / Stainless Steel
  • Attachment Type Direct Thread
