The team at Cross Machine Tool takes the challenge of producing advanced AR components to another level with the re-engineering and manufacture of their Ultra Precision Upper Receiver.
CMT Tactical UPUR-2 AR-15 Billet Upper Receiver is an excellent choice for anyone who is looking for an upper without forward assist that’s manufactured for exceptional performance and durability. CMT changed the upper receiver blueprint for the UPUR-2 upper without forward assist and not only gave The CMT receiver sleek sides, but also thicker walls for greater rigidity. Better materials make a better product, that’s basic logic and CMT knows that so instead of the industry standard 6061 aluminum alloy, they’ve upgraded the billet used for the CMT receiver to 7071 T 6 Aluminum. 7071 makes the Cross Machine no forward assist upper 65% stronger than an equivalent upper made in 6061.
CMT Tactical uses and advanced five-axis machining centers to create the Ultra Precision no forward assist upper. When parts are machined on more common three and four-axis machines they must be set up for multiple separate operations to create a complete part. Each of those operations requires the part to be removed from the machine and remounted for the next operation. This process can breed inaccuracies in the finished part. By using a five-axis machining centers Cross Machine is able to produce components that are far more accurate to the original print and consistent to one another. When you choose an upper receiver from CMT Tactical, that step up in quality will show through in increased accuracy and better fitment. Choose the CMT Upper with no forward assist and give yourself an edge.
