Magpul MBUS Sight Set

The MBUS (Magpul® Back-Up Sight) is a low-cost, color injection molded, folding back-up sight. The MBUS Front Sight is adjustable for elevation and fits most 1913 Picatinny-railed hand guards, but is specifically tailored to the AR15/M16 platform.

Features:

•Impact resistant polymer construction provides light weight and resists operational abuse

•Spring-loaded flip up sight easily activated from either side or by pressing the top

•Detent and spring pressure keeps sight erect but allows for unobstructed folding under impact, etc.

•Clamps to most any MIL-STD-1913 Picatinny/STANAG 4694 railed hand guard and provides the same height-over-bore as standard A2 irons

•Protective wings shield the spring-locking A2 front sight post

•Elevation adjustment tool included, but most aftermarket A2 front sight adjustment tools may be used as well

Dirty Bird Industries Enhanced Bolt Carrier Group .223/5.56

The Dirty Bird Enhanced Bolt Carrier Group for .223/5.56 features a unique carrier design with practical improvements in two key areas:

• Strategically relocated load bearing surfaces reduce carrier tilt/can’t during recoil, thus increasing reliability and longevity.
• Additional wall thickness in the gas exhaust port area for added strength and rigidity.

The 9310 Bolt is machined to mil-spec dimensions and then the external surfaces including the lugs are CNC ground after the heat treating process to ensure a very precise fit. The bolts themselves feature the same Black Nitride finish as the carrier and are High Pressure (HP) Tested and Magnetic Partical Inspected (MPI) in accordance with Mil-STD-1816 specifications.
