Created by JimC innovations for the Drozd mp-661k airgun, the Mock Suppressor kit. This kit provides better performance as well as adds a fake (non functioning) suppresor for look and feel ( in no way does this actually reduce sound) to your drozd bb gun. Included in the kit 1 15" barrel and 1 fake suppresor with detailed instructions.

Each kit is made entirely of steel. It is then bead blasted to give it a “Tactical” matt finish and hot blued just like a real gun.
In addition the breech end of the barrel is heat treated to harden it (a MUST when you go full auto using steel BBs).
This feature, along with the hot bluing is exclusive to these kits.
