Dirty Bird 10.3″ 5.56 NATO 1:8 V2 M-LOK Upper Assembly

The Dirty Bird 10.3″ V2 Upper Assembly is the next iteration in Dirty Bird’s Line of Complete Uppers.  We wanted to make an upper that could go on an AR Pistol or SBR and be used for a variety of applications, such as: Home Defense, Range Plinking, or Suppressed Fire.

The barrel is made from domestically sourced 416R Stainless Steel to be able to provide peak accuracy and features a 1:8 twist to be able to stabilize the majority of ammo grains that are on the market today.

Speaking of suppressors, the Dirty Bird 10.3 5.56 NATO V2 comes equipped with a SureFire 3 Prong Flash Hider w/ Suppressor Adapter – 5.56 which serves as a rock-solid mounting adapter for SureFire SOCOM Series 5.56 suppressors.

The upper is built on a top-tier 7075 forged upper receiver, and fitted with a Dirty Bird SMRS V2 Handguard. Key features of this handguard include:

• Patented ASAL (Anti-Slip, Anti-Lift) mounting system
• Included M-LOK QD Mount
• “Competition Cut” top rail

This upper ships with an MOA Guarantee and is covered by the Dirty Bird Limited Lifetime Warranty.
