Description

Hang a heavy can off the end of a .338 and you'll feel it every time you shoulder the rifle. That's the problem the Maxim Defense PRS-338 was built to solve. The whole point of the PRS line is strength-to-weight ratio, and this one nails it: a 7075-T6 aluminum tube, core, and mount keep the full package at right around 19 ounces, while a Grade 5 titanium thread insert at the mounting end prevents the galling that plagues bare aluminum threads. It attaches direct thread in the common 5/8×24 pattern, measures 11 inches long with a 1.75 inch outside diameter, and wears a Type III hardcoat anodized black finish.

Why the PRS-338 Earns a Spot on a Precision Rifle

Maxim designed this suppressor around two jobs: mountain hunting and Precision Rifle Series style competition, and the same qualities serve both. Beyond taming sound and flash, the design cuts recoil and keeps gas blowback in check, which matters a lot on semi-autos where extra back pressure can speed up the cyclic rate and dirty up the action. Because it handles .338 magnums, it also swallows smaller precision cartridges without complaint, so one tax stamp can cover your .338 Lapua rig, your 6.5 Creedmoor match gun, and your .308 hunting rifle.

Simple to Own, Simple to Maintain

Inside is Maxim's MonoKore setup, a straightforward three-piece design that comes apart with common tools, so cleaning day doesn't require a trip back to the factory. The core even has integrated carbon cutters that scrape fouling from the tube as you disassemble it, a small touch you'll appreciate after a few hundred rounds.

Where the PRS-338 Fits Best

Aluminum construction makes this a light to mid-duty can, ideal for the deliberate pace of hunting and match shooting rather than mag dumps. If you carry a rifle into the backcountry or spend weekends behind a precision gun, the reduced muzzle weight is something you'll notice on the first stage and every one after. Made in the USA and backed by Maxim Defense, it's a smart way to quiet down a big-bore rifle without turning it into a boat anchor.

Frequently Asked Questions

Can I use the PRS-338 on rifles smaller than .338 caliber?

Yes, and that's one of its biggest selling points. Since it's rated for .338 magnum cartridges, it handles smaller precision rounds like 6.5 Creedmoor and .308 Win with ease. The bore is slightly oversized for the smaller calibers, but the practical difference in suppression is minimal, so one can covers several rifles.

Is the Maxim Defense PRS-338 rated for rapid fire or full auto?

No, this is a light to mid-duty suppressor built around aluminum construction to save weight. Maxim specifies a controlled rate of fire of about 20 rounds, then letting the can cool back down. That pace is a non-issue for hunting and precision match work, which is exactly what this suppressor was designed for.

Can the PRS-338 be taken apart for cleaning?

Yes, it's fully user serviceable. The MonoKore three-piece design disassembles with common tools, and the core has integrated carbon cutters that help scrape fouling out of the tube during teardown. That means routine maintenance at home instead of shipping it off.

How does the PRS-338 attach to a rifle?

It's a direct thread suppressor in the standard 5/8×24 pattern, so it spins onto most .30 cal and larger threaded barrels without any extra mounting hardware. The Grade 5 titanium thread insert is a smart touch, since it prevents the galling you'd get threading bare aluminum on and off a steel barrel repeatedly.
