The HGA-1301 Zhukov Retrofit Kit allows current 1301 Handguard Assembly users to take advantage of our newly designed front and rear adapters without having to buy a new Zhukov handguard.

The new rear adapter is a one piece design, milled from 6061 aluminum and Type III black hard coat anodized. This new design is not only lighter and stronger, but most importantly it opens up the entire rear M-LOK slot. This allows for the proper mounting of M-LOK accessories such as Match Savers and/ or sling mounts.

The new front adapter takes the Zhukov to the next level. It fully contours the Zhukov top to bottom, and supports it inside and outside. This eliminates flex in the handguard and adds durability. The integral slots allow a more durable light mounting solution while placing the light further forward, helping to cut town on barrel shadow. The new front adapter takes advantage Nylon 12’s properties along with Multi Jet Fusion additive manufacturing to achieve incredibly difficult geometries and features without sacrificing strength.

Your choice of Black or FDE.
