SIG SAUER MCX (5.56MM) SBR 11.5" BARREL WITH OSS HX-QD 556 SUPPRESSOR (FLASH CAP)

SIG SAUER MCX SBR (5.56MM) w/OSS HX-QD 556 SUPPRESSOR

Unlike every other firearm on the market, the SIG MCX was built for optimum performance with the 5.56mm cartridge and suppressor ready handguard.  The outcome is a firearm with superior suppression capability and enhanced reliability with a two-position gas block that makes the SBR versatile in any configuration of ammunition.  Each SIG MCX features an aluminum M-LOK handguard extending a couple of inches past the 11.3" barrel to allow for the suppressor to set inside the handguard, AR-style lower controls and metal magazines.  A revolutionary recoil system does not require a buffer tube, allowing for side-folding and telescoping stocks.  A picatinny top rail allows for the mounting of lights or optics.  The aluminum forend allows for rail sections to be added where they are needed, permitting the attachment of accessories.  The lower receiver offers familiar AR-style controls. Completely ambidextrous controls include the safety, magazine release and charging handle.

OSSHX-QD 556

A short and extremely durable suppressor, the HX-QD 556 – updated with our newly designed flash cap – is built with patented and proven Flow-Through® technology, delivers sub-140 dB and zero flash performance, is full-auto rated, easily passes the USSOCOM Reliability Stress Test, and has no minimum barrel restrictions – it’s designed and built for extreme use.

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 was designed with minimal length in mind. The low volume and light weight make this suppressor ideal for shooters more concerned with size than maximum sound reduction. Sound pressure levels are measured at the shooters ear to comply with current military specifications:

• 136 – 140 dB on 20” AR15 DI using commercial grade 55 gr ammo
• 138 – 142 dB on 16” AR15 DI using commercial grade 55 gr ammo
• 142 – 146 dB on 10.5” AR15 DI using commercial grade 55 gr ammo
