    Hydra-Matic M16A1 lower

    Posted by Jay Phelps on Apr 17th 2023

    Finish and workmanship is fantastic on receiver. Fully expect the fit to be the same when I get the final product assembled. Chris and Intl Mil Co continue to produce great equipment for niche applications, that typically have discerning clientele.

    This lower basically sets the standard for a M16A1 for those in need of a lower for cloning. Fit and finish is perfect, anodizing is great. Great company with great products.

    A very long wait, but definitely worth it for the quality of the receiver. Customer service and communication were good.

    M16A1 GM receiver

    The fit and finish is excellent! The detail that has been put into these is outstanding. The roll stamping add visual and tactile elements lacking from the engraved receivers out there. The anodizing is the perfect early grey shade. There is even forging flash in the right places. If you're building clone correct rifles, or in need of a receiver to go with a surplus parts kit, this is the only way to go!
