Seekins Precision SPRO3G Pro Series Rifle (18")*

The SPRO3G is designed and built as a no holds barred 3gun competition rifle. By combining the best configuration and components available with the industry’s leading quality and precision standards, the result is a rifle that’s optimized for any competition or sporting application.

Building the ultimate competition rifle starts by combining the proven iRMT-3 Upper Receiver with an SP223 Ambi Billet Lower Receiver. Both are CNC Machined from 7075-T6 billet aluminum. The iRMT-3 Upper Receiver’s hand guard mount is machined into the upper to strengthen the receiver and maintain accuracy throughout long shot strings. Seekins’ SP223 is the best lower receiver available. Also machined from 7075-T6 billet aluminum, it has an ambidextrous bolt release and selector switch, as well as the Seekins Precision Billet Mag Release button to make weapon manipulation smooth and quick, even in adverse conditions. The beveled mag well assists with rapid, positive magazine changes. Coupled with the receiver is the Seekins Precision SP3Rv3 Key Mod hand guard. Free floated and flat on the bottom, the SP3 gives you two points of contact, adding stability for precision shooting. Both receivers and the hand guard are Mil-Spec Type III Hardcoat Anodized matte black.

The Seekins Precision 18” barrel was chosen for both quick target acquisition as well as long range performance. 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, the barrel comes standard with the Seekins Precision Advanced Tactical Compensator. Designed using CFD (Computational fluid dynamics) analysis software to design the best compensator available, it reduces felt recoil and muzzle rise for quicker follow up shots that are so important in competition.

Tuning the gas system is critical to maximize performance and reliability. The SPRO3G comes with the Seekins Precision Adjustable Gas Block, Melonited Gas Tube and Low Mass M16 Bolt Carrier Group to fine tune the gas system for smoother cycling and operation. Melonite coated to resist corrosion and wear as well as aiding 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.

Other high performance features include the CMC Single Stage Curved Trigger with 3.5lb pull, an Ergo Tactical Deluxe grip and the Magpul STR butt stock.
