OSS HX-QD 556

An extremely rugged suppressor, the HX-QD 556 is built with proven Flow-Through® technology, delivers hearing safe mid-130s dB performance, has no barrel length restrictions, is full-auto rated, and easily passes the USSOCOM Reliability Stress Test – it’s the ideal suppressor for all 5.56 rifles.

Materials & Finish: Unlike traditional suppressors that manage trapped gas, intense heat and pressure with blast baffles, OSS’s Flow-Through technology redirects expanding gases forward allowing us to use 17-4 stainless steel deflectors and internal Grade 5 Titanium coils.  The result is a remarkably cooler and extremely durable suppressor. The HX-QD 556 has a fully-welded outer body made of 17-4 heat treated stainless steel coated with C-series high temperature black Cerakote®.

Sound Pressure Levels:  The HX-QD 556 is the optimal choice for the widest range of 5.56 caliber rifles.  Sound pressure levels are measured at the shooters ear to comply with current military specifications:
  • 130 – 134 dB on 20” AR15 DI using commercial grade 55 gr ammo
  • 133 – 137 dB on 16” AR15 DI using commercial grade 55 gr ammo
  • 138 – 142 dB on 10.5” AR15 DI using commercial grade 55 gr ammo

FAST™ LPVO Mount Offset Optic Base – FDE

FAST™ is a series of mounts and platforms that provide end users with a quicker sight picture than standard height mounts. A taller optical centerline (mechanical) height provides faster/easier reticle acquisition while wearing electronic ear pro/communication headsets, night vision goggles, gas masks, and plate carriers that can impede a natural shooting position. It allows for more rapid visual processing of the battlefield by promoting a heads-up posture.

The FAST™ LPVO Offset Optic Base attaches to either the forward or rearward mounting holes in the FAST™ LPVO Scope Mount. Together with a FAST™ LPVO Offset Optic Adapter Plate, it provides a base for attaching any number of mini red dot sights directly to the scope mount. The Offset Optic Base places mini red dot sights at a 35 degree offset from the scope tube for faster transitions. When used with the Optic Adapter Plates, the mini red dot will have a mechanical centerline of 2.05” above the rail.

The FAST™ LPVO Offset Optic Base is only compatible with the FAST™ LPVO Scope Mount and requires a FAST™ Offset Optic Adapter Plate to function.

The FAST™ LPVO Offset Optic Base is built from 7075-T6 Aluminum and Type III Hardcoat Anodized Black or FDE*.

It allows for more rapid visual processing of the battlefield by promoting a heads-up posture.

The FAST™ LPVO Scope Mount series addresses the above-mentioned issues for and the rising popularity of Low Power Variable Optics on the battlefield. The FAST™ LPVO Mount series is available in 30mm and 34mm variants to accommodate all popular commercial and military scopes. It places the scope’s mechanical centerline at 2.05” above the rail. This height provides all the advantages of a tall mount while still being compatible with Clip-On Night Vision Devices (CNVD).

Keeping in tradition with the FAST™ line, the LPVO Mount series is more than a traditional scope mount. To accommodate the need for backup red dot sights, the mount accepts an optional Offset Optic Base (sold separately) that can be forward or rearward mounted. Additional Optic Adapter Plates are available with footprints for popular mini red dot sights. These plates have three positions to which they can be mounted on the Offset Optic Base, allowing users to fine tune the placement in relation to the MRDS’s size and host scope’s turret. The modularity allows users to change the mini red dot as they see fit.

FAST™ FTC Aimpoint Magnifier Mount

FAST™ is a series of optic mounts and platforms that provide end users with a quicker sight picture than standard height mounts. A 2.26” optical centerline height provides faster/easier reticle acquisition while wearing electronic earpro/communications headsets, night vision goggles and gas masks and allows for more rapid visual processing of the battlefield by promoting a heads-up posture. A heads-up posture also helps users maintain a neutral spine position which is more comfortable while wearing helmets, plate carriers, and other heavy gear.

FAST™ FTC Magnifier Mounts feature the first ever Flip-To-Center (FTC) mechanism (patent-pending), providing stowage completely within the footprint of the weapon’s receiver while not occluding the host optic’s sight picture at all. This provides the most optic capability with the lowest profile during all modes of operation. The revolutionary FTC function completely solves the problem posed by legacy flip-to-side magnifier mounts (when disengaged, the magnifier hangs off the side of the gun, creating a major snag hazard). FAST™ FTC Magnifier Mounts completely eliminate this danger and utilize a force-to-overcome mechanism for rapid transition. Designed for Aimpoint® Magnifiers (3XMag-1, 3X-C) and some other 30mm magnifiers.

FAST™ FTC Magnifier Mounts come complete with American Defense Manufacturing® patented QD Auto-Lock™ Lever.
