Seekins Precision SBR8 300 Blackout Specifications

The SBR8 is designed for use with a suppressor (not included). It is configured to keep the overall length to approximately that of a standard carbine by the use of a short barrel and the Seekins Precision MCSRv2 M-LOK handguard. This allows the handguard to cover part of the suppressor, protecting the shooter from suppressor and letting the shooter use a comfortable support grip further forward on the handguard.

The SBR8 uses the iRMT-R Upper Receiver and SP223 Ambi Billet Lower Receiver. Both are CNC Machined from 7075-T6 billet aluminum. The iRMT-R Upper Receiver’s handguard mount is machined into the upper to strengthen the receiver and maintain accuracy throughout long shot strings. Seekins’ SP223 lower receiver is machined from 7075-T6 billet aluminum, 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 12” MCSRv2 M-LOK handguard for use with a suppressor. The length allows for a forward hold or closer to the receiver for CQB situations. Both receiver and handguard are Type III Hardcoat Anodized matte black.

An 8” Seekins Precision match barrel with the pistol length gas system is perfect for this suppressed configuration. Seekins Precision's barrels are all inspected four times to insure match grade tolerances for maximum accuracy and performance. Chambered in .300 Blackout with 5/8x24 threading.

Tuning the gas system is critical to maximize performance and reliability. The SBR8 comes with the Seekins Precision Adjustable Gas Block, Pistol Length Gas Tube and M16 Bolt Carrier Group to fine tune the gas system for smoother cycling and operation. All are Melonited 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.

Other upgraded features included is a Magpul MOE+ grip and Odin Works Close Quarters Stock.

*Firing this rifle without a suppressor can lead to catastrophic damage to the handguard as well as your hand.
