The FN PS90 has always turned heads with its bullpup shape and 5.7x28mm punch, but the factory grip angle and limited mounting real estate leave a lot to be desired once you start trying to add gear. Strike Industries built the SMC-90 chassis specifically to fix that, giving PS90 owners a way to modernize their gun's ergonomics without touching the receiver or fire control group that makes it run.
The biggest complaint most people have with the stock PS90 shell is the grip angle, and that's exactly where Strike focused their redesign. The SMC-90 chassis reshapes the grip for a more natural hand position, which translates to better control when you're moving the gun around or shouldering it quickly. Paired with that is an adjustable cheek rest, so instead of fighting the factory cheek weld to line up an optic or the stock sights, you can dial in a height that actually matches how you shoot.
Once the ergonomics are sorted, the SMC-90 opens things up for accessories. Lower and rear 1913 Picatinny rail sections give you room for foregrips, lights, or other hardware that the original PS90 shell simply couldn't accommodate. Integrated sling mounts let you run either a single point or two point setup depending on how you carry the gun, and internal cable routing keeps any wired accessories tucked away instead of flopping around loose.
This chassis is built to work with the receiver and fire control group already in your PS90, so there's no need to source additional internals to make it function. It's a drop-in style upgrade that swaps out the outer shell while keeping the parts that actually make your PS90 shoot right where they belong. For anyone who's wanted to keep the PS90 platform but felt boxed in by the factory ergonomics and lack of rail space, this chassis is the most direct way to change that.
It replaces the outer shell of your PS90, including the grip and stock area, giving you a new ergonomic layout and added rail space. Your existing receiver and fire control group stay in place and simply drop into the new chassis.
Yes, the SMC-90 is built to work with commercially available FN Herstal PS90 receivers and fire control components. You won't need to source any additional internal parts to get it running.
Definitely. The chassis includes integrated sling mount points for single or two point slings, plus lower and rear 1913 rail sections for lights, foregrips, or other gear you want to add.
No, this particular kit covers the chassis itself, which includes the grip, stock area, and cheek rest. Strike Industries sells the aluminum handguard separately if you want to upgrade the front end too.
