Seekins Precision Pro Series 16" SPROV3 Comp. Upper

The Seekins Precision SPROV3 complete upper receiver is perfect for building a quick handling, precision rifle accurate carbine. It is configured to keep the overall length to approximately that of a standard carbine by the use of a 16 inch barrel and the Seekins Precision MCSR Key Mod hand guard.

The SPROV3 uses the iRMT-R Upper Receiver, CNC Machined from 7075-T6 billet aluminum. The iRMT-R Upper Receiver’s hand guard mount is machined into the upper to strengthen the receiver and maintain accuracy throughout long shot strings. Coupled with the receiver is the Seekins Precision 15” MCSR Key Mod hand guard. Both the receiver and the hand guard are Type III Hardcoat Anodized matte black.

A 16” Seekins Precision stainless steel barrel is perfect for this suppressed configuration. Precision CNC machined from a premium stainless steel blank, each barrel is inspected four times to insure match grade tolerances for maximum accuracy and performance. Chambered in .223 Wylde or .300 Blackout, a Seekins Precision Melonited Flash hider is included.

Tuning the gas system is critical to maximize performance and reliability. The SPROV3 comes with the Seekins Precision Adjustable Gas Block, Melonited Gas Tube and M16 Bolt Carrier Group to fine the gas system for smoother cycling and operation. All are Melonite coated to resist corrosion and wear. This also aids in easier cleaning, as carbon build up will not adhere to the non-reflective coated surface as much as it does on standard Parkerized finishes.
