SKU: 18106 Categories: AR15 & AR10 Upper Receivers, AR-15 Upper Receivers, Overstock DescriptionAre you left handed? Tired of having to deal with ejected shell casing and hot gas exploding right in front of your face? Well, maybe it is time to build a dedicated left handed AR-15 with the Cross Machine Tool UPUR-1LH upper receiver. It features the exact same specs as the standard model but is flipped for left side ejection. If you are not familiar with these models of upper receivers, they are machined from a billet of 7075-T6 aluminum allowing for more precise dimensions and thicker walls for more durability. It is then finished with a type III class II black hardcoat anodizing to protect against corrosion and wear. This upper receiver is compatible with Mil-Spec lowers, upper parts, and charging handles, however, is only compatible with the Stag Arms left hand bolt carrier group or comparable BCGs with the same dimensions. The M4 flat top picatinny rail features engraved T-marks for optic placement. The CMT left handed AR-15 billet upper receiver is made to improve usability with left handed shooters.

- Machined from 7075-T6 billet aluminum
- Class III type II hardcoat anodized finish
- Engraved T-marked flat top upper receiver
- M4 feed ramps
- Compatible with Mil-Spec parts except BCG
