Why Choose the PS90 SBR?

The PS90 short barrel rifle (FDE) configuration maximizes the strengths of the bullpup design — keeping the rifle compact, lightweight, and highly maneuverable without sacrificing firepower. The shorter barrel enhances suppressor handling while retaining the PS90's legendary 5.7x28mm performance. Whether you’re creating a duty setup, suppressed host, or collectible piece, the PS90 SBR is a top-tier choice.

About the CMMG 10.4" Barrel and Thread Adapter:

This SBR features a 10.4-inch chrome moly barrel manufactured by CMMG for reliable PS90 operation. The installed 1/2x28 thread adapter enables use with standard suppressors and muzzle devices. Proper installation preserves the PS90's unique floating-barrel delay system for optimal function and accuracy.

Professional Conversion by Armory of Kings:

Every SBR conversion and NFA-compliant engraving is performed by Armory of Kings (National Firearm Sales Inc, a licensed FFL/SOT). Our gunsmiths professionally shorten the factory PS90 and engrave the receiver to ATF standards. In addition to OEM markings, the receiver is engraved with:

ARMORY OF KINGS
BOCA RATON, FL

Frequently Asked Questions (FAQ)

What is included in the FN PS90 SBR (FDE) package?

The FN PS90 SBR (FDE) package includes a new factory FN PS90 rifle, professionally converted to a short-barrel rifle by Armory of Kings. It features an installed CMMG 10.4" barrel and your choice of muzzle device — CMMG 1/2x28 thread adapter, CMMG P90-style flash hider, or PS90 KeyMo/KeyMicro compensator — along with NFA-compliant receiver engraving. A factory 30- or 50-round magazine and accessories (subject to availability) complete the package.

Is this a registered SBR?

Yes. This is a registered short-barrel rifle (SBR) with ATF-compliant engraving. It will transfer to your FFL/SOT dealer via Form 3 before a Form 4 transfer to you. All NFA rules apply.

Is a tax stamp required to own the PS90 SBR (FDE)?

Yes. Taking possession of this SBR requires an approved ATF Form 4 and a $200 NFA tax stamp. Your FFL/SOT will help with the transfer process.

Can I request the original 16" barrel and shroud?

The original 16" barrel and shroud are removed during the SBR conversion and are not included in the package.

Can I attach a suppressor to the PS90 SBR?

Yes. The SBR is threaded 1/2x28 and suppressor-ready. Contact us to select the ideal muzzle device and suppressor to ensure compatibility and proper operation.

Who performs the SBR conversion and engraving?

The SBR conversion and NFA-compliant engraving are performed by Armory of Kings (National Firearm Sales Inc). Our FFL/SOT ensures all work meets ATF standards. The receiver is engraved with:
ARMORY OF KINGS
BOCA RATON, FL

What are the benefits of a 10.4" barrel on the PS90?

The 10.4" barrel shortens the PS90 into a lightweight, maneuverable SBR without compromising the firearm's reliability or the 5.7x28mm cartridge's effectiveness — making it ideal for close-quarters, tactical, and suppressed setups.

Does converting the PS90 to an SBR affect the factory warranty?

Yes. SBR conversion voids the original FN factory warranty. Armory of Kings provides support for the installed barrel and muzzle device but cannot guarantee the complete firearm.
