The HK416D Project
​We partnered with two outstanding manufacturing and laser engraving/cerakote companies to create and bring completed HK416D lowers to market. Our 416 lowers are specifically M16 pocket cut and laser engraved to the highest degree of accuracy we are able to achieve. Those looking to build their own HK416 can purchase the stripped lower from us and know that it has been quality checked. No waiting or sending your stuff to have it worked on with the risk of not ending up with the right color, logos, lettering or placement.
