Worker MOD Metal Stefan Breech Kit is built for perfection using the highest quality precision-machined computer numeric control (CNC) aluminum that will improve modded and stock foam dart blasters. Its parts come in a beautiful anodized aluminum finish that keeps them free from corrosion, provides a hard and mostly scratch-resistant surface, and in a beautiful color.

The kit is the ultimate Nerf LongStrike internals modding kit. The re-engineered bolt and breech maximize the aerodynamic efficiency that transform the coil power into rapid air flow. This is a drop in kit that transforms the Longstrike into a direct plunger blaster. Direct plunger systems greatly increase the amount of usable air volume while simultaneously eliminating the large amount of dead space found in the original reverse plunger. What sets our direct plunger system apart from blasters like the Retaliator is the static plunger body.

Advance modding skill does require, you need to remove the plunger, bolt module and muzzle on your longstrike and replace this metal kit. This kit only compatible to Stefan/ Short darts mags.
