What Is Inside The Seekins Precision 300 Blackout Complete Pistol Upper

Starting with a true match grade 8-inch 300 Blackout barrel that can shoot a tighter MOA that many shooters can manage. All the barrels produced by Seekins are machined from the finest stainless steel blanks and are given no less than four inspections to ensure their quality and accuracy. This 300 Blackout upper SBR is then treated to M4 feed ramps. If you're not familiar with those, they're simply feed ramps that are machined further to better feed ammo reliably. Seekins backs these up with an M-16 design bolt carrier group. This style BCG carries more mass and a longer, heavier firing pin that many shooters prefer simply for durability. However, this design allows you to fire full auto if you're so blessed with a license to do so. Then add 5 separate machined in anti-rotation QD mount points and what more could anyone want?

The NX Series .300 Blackout NX8 upper includes the Seekins Precision NX15 upper receiver. This Seekins billet upper is CNC-machined from 7075-T6 billet aluminum for maximum strength. The included 7” NOXs M-LOK handguard is extremely lightweight and infinitely adaptable because of it's M-LOK system. This makes the upper is perfect for tactical use. Both the receiver and the handguard feature a Type III Hardcoat Anodized matte black finish.

The NX8 also includes an adjustable gas block that allows you to tune your gas system for maximum performance. The gas system components are all coated with Melonite to resist corrosion and wear. Melonite coatings are also easier to clean than the standard Parkerized finishes.
