Description
The Tactical Solutions Pac-Lite TSS Integrally Suppressed Upper .22 LR, FO Sights, Black is a complete, ready-to-install upper receiver assembly for your AR-15 platform. It features a built-in suppressor, making your .22 LR rifle hearing-safe and incredibly fun to shoot without the hassle of a separate NFA item. I’ve put thousands of rounds through similar setups, and the convenience is hard to beat. This unit is drop-in ready for your standard AR-15 lower, no gunsmithing required. At $524.98, it’s a straightforward path to a quiet plinking or small-game rifle.

Here’s the thing—this isn’t a baffled silencer you screw on; it’s a permanently attached shroud that contains the report. The result is a package that keeps your rifle at a legal 16.5+ inches overall, so you avoid NFA paperwork. I’ve found it pairs perfectly with a dedicated .22 LR bolt carrier group in a standard AR lower, like those from CMMG or Black Dog Machine. The fiber optic sights are a nice touch, giving you a usable sight picture without needing to add an optic immediately, though the Picatinny rail is there if you want one. Weighing in at just under 3 pounds for the complete upper, it balances well on most lowers.
Who This Upper Is For
This is for the shooter who wants a quiet, hassle-free .22 LR AR without diving into the NFA world. It’s ideal for backyard plinkers, small game hunters who need discretion, or trainers looking for a low-cost, low-recoil option that’s easy on the ears. If you already have an AR-15 lower sitting around, this upper transforms it into a supremely quiet rifle in minutes. It’s also a great choice for Missouri residents who enjoy varmint control on their property without disturbing the neighbors.
Straight-Talk Pros & Cons
Pros: The biggest advantage is simplicity. No tax stamp wait, no separate suppressor mounts, and it’s always ready. The fiber optic sights are genuinely useful in low light. Performance with standard velocity ammo is impressively quiet—often just the “click” of the firing pin and the impact downrange. Since it’s a complete upper, installation is a matter of two pins.
Cons: It’s dedicated to .22 LR only. The suppressor is not user-serviceable, so you’ll need to be mindful of ammo cleanliness. While quiet, it won’t be as quiet as a high-end, traditional .22 suppressor with subsonic ammo due to the shorter barrel length inside. And at just over five hundred dollars, it’s an investment, but you’re paying for the integrated design and convenience.
Frequently Asked Questions
Q: Is this considered a suppressor, and do I need a tax stamp?
A: No. Because the suppressor is permanently attached and the overall barrel length meets or exceeds 16 inches, it is not regulated under the National Firearms Act (NFA). It is treated as a standard rifle upper receiver.
Q: What kind of ammunition works best?
A: Standard velocity (1050-1100 fps) .22 LR rounds are ideal. They stay subsonic out of the short barrel, ensuring maximum noise reduction. Avoid hyper-velocity ammo, as it will break the sound barrier and create a sonic crack.
Q: Can I clean the suppressor?
A: The integral suppressor core is not designed for user disassembly. To maintain performance, use quality, non-lead-fouling ammunition and clean the rifle’s chamber and bolt face regularly. The design manages fouling well with proper maintenance.
