Seekins Precision SP10 .308 Rifle 18"


After two years of tireless development and testing, Seekins Precision has introduced the SP10 308, our large frame AR of unrivaled quality, accuracy and performance. 

Based on the excellent and proven iRMT upper receiver, CNC machined from 7075-T6 billet aluminum, the top Picatinny rail extends over the barrel mount to strengthen the receiver and provide more space to mount optics.  Coupled with the receiver is the Seekins Precision SP3R free float handguard.  Flat on the bottom, the SP3R aids stability for precision shooting.  The stainless steel match-grade barrel is specifically contoured to balance the rifle for superior handling performance and weight reduction.

The Seekins Precision mission of unrivaled innovation and performance drove the development of the lower receiver.  Also machined from 7075-T6 billet aluminum, the SP10 308 is fully ambidextrous due to superior weapon controls such as the magazine release, selector switch and ambidextrous bolt switch that allows the shooter to lock back or release the bolt with a single finger.  Accuracy demands an excellent trigger and the SP10 308 delivers with a 3.5 tuned fire control that guarantees out of the box performance.  The proprietary buffer system is housed in a carbine length tube and is fitted with a Magpul STR stock. The SP10 308 is the pinnacle of large frame AR development.  Premium features and components come standard to increase accuracy, functionality and reliability.  The SP10 308 is hard coat anodized matte black.
