Upper Receiver; Gen1 - BLEM
- Machined from Cerro Forge 7075-T6 Aluminum forgings
- Type III hardcoat anodized
- Machined Pocket at front for LDR1 Index Pin
- *Dust Cover Assembly & Forward Assist not included
- YOU CAN ADD an Aero Precision Upper Parts Kit in the drop down menu.
*The Upper Receivers DO NOT come with the LDR1 Index Pin. That part is included with our rail.
These Upper Receivers are marked as "blemished". This is due to the Machined Pocket for the LDR1 Index Pin being off-center (a specific spec to our company). The fit, finish, function and use with other companies' components with these blemished uppers is the same as our standard Gen1 Upper Receivers.
These Gen1 Upper Receivers can still be used with our LDR1 (or any other rail), you will simply want to refrain from installing the Index Pin. Use of the Index Pin with these uppers could result in the LDR1 not aligning properly.
