True to our beliefs and standards we couldn’t be happier with ZEV manufacturing our receiver sets. The upper and lower match perfectly without any play, the anodizing is rich and consistent and the machining is bar none.

    5/5 stars. Top quality parts. The tolerance of the lower and upper is amazing. Paired with a 13.5 MK8 rail from Geissele, it looks amazing. Especially with that good ole Ape logo on the top and side.🦍

    This set just oozes quality. The finish is top notch and the fitment is among the best I’ve ever handled. I plan to pair this with a Ripcord 13″ rail for maximum Chad-ness.
