Pugio-9 Furniture and Controls Lower

Our lowers are assembled by SOTAR-trained master armorers in North Carolina using components manufactured exclusively in the USA.

The Pugio-9FC lower makes substantial improvements to the EM model intended to improve the performance and ergonomics of an already great weapon system.

The Spatha-9FC retains the following features of the EM model:

• Aero Precision EPC Stripped Lower Receiver
  • The Aero EPC lower has the best combination of features, quality, and value for a dedicated PCC.  It offers unlimited potential for a build.
• Trigger: Timney Impact AR PCC Trigger
  • You should always use a PCC-specific trigger in your PCC build; the added stress of the direct blowback design of the pistol caliber AR will break standard hammers (this is why most triggers will come with a “not for PCC” disclaimer).  Timney makes the best PCC-specific trigger on the market.  The Impact AR trigger is their budget-friendly PCC trigger.
• Everything Mil-Spec or Better
  • We build our lowers with true Mil-Spec or better components.  It is important to emphasize this because many claim to use Mil-Spec components, but use components made of inferior materials/quality.  We refuse to cut corners to save a buck.

The FC model includes the following upgrades to the EM model:

• Buffer Spring: David Tubb Flat Wire AR-10 Buffer Spring
  • The buffer spring is one of the most forgotten/neglected components of the AR, but is also one of the most important. The David Tubb Flat Wire Spring is is phenomenal upgrade, providing immediate improvement to the performance and longevity of the buffer system. The Tubb FWS offers additional closed bolt resistance (which increases the bolt lock time), and offers a more gradual and consistent increase in spring pressure through the cycle of the reciprocating mass.
• Buttstock: Magpul MOE Buttstock
  • The MOE carbine buttstock is probably one of the most recognized aftermarket upgrades, and for good reason. It improves the ergonomics and operability of the weapon system.
• Grip: Magpul MOE Pistol Grip
  • The grip is your most tactile interface with the weapon. The boxy profile of the Magpul MOE grip is perfect for pistol builds, as it helps orient the pistol in the right direction.
• Pivot/Takedown Pins: Battle Arms Development Steel Enhanced Pin Set
  • Pivot and takedown pins aren’t sexy and you may not use them often. But when you do, you want disassembly of the receivers to be a piece of cake. For the FC and DC levels, we upgrade the pins to Battle Arms Development pivot/takedown pins, which are slightly longer, have an improved grip surface, and have depressions on the left side of the receiver to aid in disengaging.
• Receiver Extension: TBD
  • TBD
• Safety Selector: Radian Talon Ambidextrous Safety Selector
  • We like to be able to control our weapon from either side of the receiver. Most people do. For the FC and DC levels, we move up to the gold standard in safeties: the Radian Talon.

Critical finishes and dimensions of individual components are inspected before they we accept them into inventory.  To learn more about our quality control gauging and inspection, visit our Quality Promise page.

Each upper receiver includes the following assembly and QC steps (full schedule of all 82 points of inspection for our builds can be found in our Quality Promise page; note that some do not apply to the PCC):

• Receiver extension (buffer tube) threads lubricated with AeroShell.
• Receiver extension castle nut torqued to 40 ft. lbs.
• Receiver extension castle nut properly staked in two locations.
• Full lubrication per our standard procedure.
• Full safety and function check per our standard procedure.
• Live fire test with 3 rounds of Federal 147gr (troubleshoot and correct root cause of any malfunction).

The tables below detail what we put in the lower and what you are paying.
