What Buyers Ask
Does this use the same magazines as the P90?
Yes, the PS90 uses the same 50-round magazines as the P90, but it ships with a 10-round magazine to comply with certain state laws. You can swap in a standard-capacity magazine if your state allows it.
Can I mount a red dot or scope on this?
Yes, the PS90 has a top-mounted Picatinny rail that accepts most optics. Many buyers run a compact red dot or a low-power scope. No modification needed.
Is this legal to own in my state without a tax stamp?
Yes, the 16.04-inch barrel makes it a rifle under federal law. No NFA tax stamp required. Check your local laws for magazine capacity restrictions — this one ships with a 10-round mag.
