High Plains CNC is your one stop shop for completing your 80% AR-15 lower. With our service you follow a few simple steps using our pre-programmed CNC to mill out the fire control pocket and make the necessary holes to finish your lower. In short, you walk in with a paperweight and 15-minutes later walk out with a fully functional receiver that you made.

Please note, if you do not have an 80% lower in your possession, we have them delivered to our location daily so your 80% lower can be waiting here when you arrive. Our 80% receivers are machined from billet (Aluminum Block). These are not casting or forgings so the quality is second to none. Machined uppers from billet are also available on site and can be matched and purchased in several colors.

Prices below reflect both the uppers each and the lowers each.
AR15 - Lowers and Uppers
Plain - $130.00 each
Black - $140.00 each
Other - $150.00 each

AR10 - Lowers only

We have had other 80% lowers machined here, however we cannot guarantee that every lower is compatible to our fixture. We can only guarantee compatibility with our machined lowers.

Please click the "Click to Schedule" button above to reserve time for the CNC mill. (please note that each reservation block is for 1 lower only; if you need to machine more than one lower, please reserve the appropriate number of schedule times)
