Ascend Armory added a new receiver set to their line of AR-15 receivers. Just like other receivers made by this company, the new set is also machined out of billet aluminum, however, what sets it apart is the existence of multiple relief cuts which make this receiver set a lightweight one.

By examining the images, I think they chose the right way of decreasing the weight of these receivers. Instead of skeletonizing the receivers and making them weaker and exposing the internal parts to the elements, they removed the material in the areas where you don’t really need it thus not compromising the structural strength of these parts.

Ascend Armory’s AR-15 billet match receiver sets are machined out of 7075-T6 aluminum and feature a mil-spec Class III Type 2 hard coat anodized finish of black color. The trigger guard is enlarged and integrated with the lower receiver. The magazine well is flared to aid guiding the magazines in. The upper receiver features M4 feed ramps and has no forward assist. The combined weight of the stripped upper and lower receivers is 13 oz.

Here is the list of parts that these Ascend Armory receiver sets come with and those you need to add to complete the receivers (quoted from Rainier Arms website).

  • 4140 Black Nitride Front and Rear Take Down Pins

    too rich for my blood

    $427.50 isnt a whole lot less than what ive been building entire rifles for

    without optics and sights of course

    and before you say "what the hell kind of quality rifle can you build for $500 anyway"

    ill say "a rifle that shoots sub moa out to 300 yards with factory ammo"

    The right side is perfect.
    Why the hell they didn’t redesign the left to mirror it I don’t know. That would have been the best ar lower on the market if they had.
    Thumbs down guys. Could have been something magical right there.
