The 338P-1 was discontinued Sept 2013 and replaced with the 338BA.
Click here to proceed to the 338BA specs page.

The 338P-1 is our high-performance big-bore suppressor. It effectively suppresses the extreme muzzle blast of the .338 magnums down to the same level as a suppressed .308. The 338P-1 is perfect for .338 Lapua Magnum, .338 Norma Magnum, and .338 Remington Ultra Magnum.

To aid suppression with the additional gas volume of the big magnums, the 338P-1 has 66% more volume than the 30P-1, but weighs only 47% more. It can also be used on 7mm and .30 caliber magnums for shooters who need to shoot extended strings of fire.

Just like the 30P-1, the 338P-1 is constructed of titanium with a fully-welded baffle core. This material and construction provides a great strength to weight ratio. It can take whatever your big-bore precision rifle can dish out.

The new 338P-1 model is quieter and stronger than the original 338P.

The 338P-1 is ideal for: extreme long-range "practical" competition shooters; varminters; predator hunters; precision tactical shooters.
