Description
Anyone who has touched off a .338 Lapua without ear pro knows big magnums are a different animal. The muzzle blast punishes you, your spotter, and everyone else on the line. That is the exact problem Fuqua Precision Machining set out to solve with the WAP 338. Instead of asking a repurposed .30 cal can to survive magnum pressures, FPM built this one from the ground up around the .338 bore, so the rifles with the most bark finally get a purpose-built answer.
Titanium Where It Counts
The whole can is titanium, which is how FPM landed at a very packable 12.7 ounces. That matters more on a .338 than almost any other platform, because these rifles are already heavy and a steel magnum can hanging off a 26 inch barrel changes the balance in a hurry. Titanium keeps the weight off the muzzle while still shrugging off the heat and pressure a Lapua-class cartridge dumps into the baffle stack. The black finish keeps things low key on a tactical build or a backcountry rifle alike.
A WAP 338 Rating You Can Lean On
Here is the part worth paying attention to: this suppressor is full-auto rated. Most of us will never run a .338 on a giggle switch, but that rating tells you how much margin FPM machined into this can. A suppressor certified for sustained automatic fire is not going to flinch at long strings from your bolt gun or gas gun, and it means the WAP 338 will still be earning its keep long after the barrel it started on is shot out. It also handles smaller bores just fine, so your .300 Win Mag, 7mm, or 6.5 can share the same can.
Who the WAP 338 Makes Sense For
Long range competitors, magnum hunters who hike for their shots, and anyone building a serious .338 will appreciate what this does for blast, recoil, and shooting comfort. Once you run a big magnum suppressed, going back to a bare muzzle or a brake is a tough sell.

Frequently Asked Questions
Can I use the WAP 338 on calibers smaller than .338?
Yes. A .338 bore suppressor works fine on smaller rifle calibers like .300 Win Mag, 7mm magnums, 6.5s, and .308, as long as your muzzle threads match or you use the right adapter. You give up a touch of sound performance compared to a caliber-specific can, but you gain one suppressor that covers your whole rifle rack.
Is the WAP 338 really full-auto rated?
It is, per FPM Gunworks. For most buyers the real value of that rating is durability headroom. A can built to survive automatic fire with magnum-class cartridges is not going to be stressed by long strings from a bolt action or semi-auto precision rifle.
How much will 12.7 ounces affect my rifle's balance?
Very little, and that is the point. Steel magnum cans often run well over a pound and a half, which makes a long barreled .338 feel muzzle heavy fast. At 12.7 ounces of titanium, the WAP 338 keeps blast and recoil in check without wrecking the handling of a rifle you might carry into the field.
Why buy a dedicated .338 suppressor instead of a multi-caliber .30 cal can?
Most .30 caliber suppressors are not rated for the pressure and volume a .338 Lapua produces, so running one is off the table. The WAP 338 was designed around the .338 bore from the start, which means proper strength, proper blast chamber volume, and performance matched to the cartridge instead of a compromise.
