The FN PS90 short barrel variant is a semi-automatic carbine that has garnered attention among firearm enthusiasts for its distinctive design and compact form factor. Building upon the innovative FN P90 personal defense weapon (PDW), the PS90 offers a civilian-legal option that retains many of the original’s unique features.
Understanding the FN PS90 Short Barrel Variant
The PS90 is the civilian version of the FN P90, designed to comply with firearm regulations by featuring a longer barrel and semi-automatic operation. However, many enthusiasts seek to replicate the original P90’s compactness by opting for the short barrel configuration, which involves modifying the PS90 to have a barrel length similar to the P90’s standard 10.4 inches.
Key Features of the PS90 Short Barrel
-
Bullpup Design
The PS90 utilizes a bullpup configuration, positioning the action and magazine behind the trigger. This design reduces the firearm’s overall length without compromising barrel length, enhancing maneuverability.
-
Top-Mounted Magazine
A hallmark of the PS90 is its horizontally mounted, translucent 50-round magazine atop the firearm. This unique feeding system allows for a high ammunition capacity while maintaining a slim profile.
-
Chambered in 5.7×28mm
The PS90 fires the 5.7×28mm cartridge, known for its high velocity and low recoil. This ammunition was developed alongside the P90 to offer improved performance over traditional handgun calibers.
Legal Considerations
In the United States, modifying a PS90 to a short barrel configuration transforms it into a Short-Barreled Rifle (SBR), subjecting it to the National Firearms Act (NFA) regulations. Prospective owners must:
-
Obtain ATF Approval: Submit ATF Form 1, “Application to Make and Register a Firearm,” and receive approval before making the modification.
-
Pay the Tax Stamp: Remit a $200 tax payment as part of the application process.
-
Adhere to State Laws: Ensure compliance with state and local regulations, as some jurisdictions may have additional restrictions on SBRs.
Performance and Handling
The short barrel configuration of the PS90 offers several advantages:
-
Enhanced Maneuverability: The reduced length makes it ideal for close-quarters scenarios and easier handling in confined spaces.
-
Distinctive Aesthetics: The shorter barrel provides a look closer to the original P90 design, appealing to collectors and enthusiasts.
However, it’s essential to note that shortening the barrel may slightly reduce muzzle velocity and effective range compared to the standard PS90 with a 16-inch barrel.
