Description
HK21 Reinforcement Rails
High strength 1045 steel CNC machined from a single piece of billet material to a precise fit with added interior radii to increase strength in critical areas to exceed HK standards. No shortcuts, like welding with other versions. Strongest on the market.
The added radius to the cut gives it additional hidden strength because there is not a 90 degree angle to fracture at the intersection.
These are best in price and best in class on the market. (Yes this is for the set, 2 rails included with product purchase)
Perfect for the newly imported HK21 build kits. These are in-stock inventory and ship same day.
