This is a factory MRGG-A Complete upper receiver. This does not include the lower.
Upper: Monolithic upper receiver machined from one piece of 7075-T6 aluminum and includes a forward assist with serrated bolt carrier. The patented upper receiver allows for quick barrel changes, making the receiver both easy to service and compatible with most LMT MWS .308 and 6.5CM barrels.
Barrel: 14.5" MRGG-A barrel chambered in 6.5 Creedmoor with a 1 in 8 twist rate. Made from stainless steel with proprietary coatings and cryogenic treatment, these barrels are incredibly accurate.
BCG: The LMT .308/6.5CM bolt carrier group was designed with the same materials and principles as the 5.56 enhanced Carrier. This BCG is exceptionally durable, and it's no mystery why it has been selected by military units around the world. Additionally, the MRGG carrier is serrated to work with the forward assist MRGG upper receivers.
