Like the product. However, I am trying to use it for 5.56. Do you have left over carriers to work w/ 5.56?
Blem run SCU Pistol Caliber Upper Receiver (.22, 9mm, 45acp etc) ! Our exclusive X Products SCU has been redesigned to be tougher, perform better, and look sharper than any other product of its kind. This 100% American-made upper boasts dual-side ejection ports with an off-side cover and interchangeable grip and off-hand slide handles, making it completely customizable to your comfort as a right or left-handed shooter.
The proprietary pistol caliber upper introduces a new charging method that allows linear operation. The non-reciprocating charging handle is locked forward with rare earth magnets to prevent movement during operation. Finally, the look of the 6061 billet cut SCU has been reborn into a tough, streamlined, more aggressive form. The uppers are blems and only work with Pistol Caliber lowers and bolt carriers, in addition the pic rail was cut incorrectly so it will only accept a single point optic any optics that require two mounting locations would require fitment. In addition the charging handles may have vertical movement, but it does not affect function. Satisfaction guaranteed, if you do not like it you can return it within 30 days. Returns will have a 20% re-stocking fee.
Bolt carrier is not supplied*
