Why it matters: A suppressed Mosin is a niche build, but the video puts a widely repeated claim about suppressors and recoil in front of a general audience, then reports the opposite result on camera.
Lujan's newest video mounts a Dead Air Wolverine PBS-1 suppressor on a WWII-era Mosin-Nagant M91/30 and takes the rifle to steel at 150, 300 and 500 yards on the factory iron sights. Posted to YouTube as "What Happens When You Suppress a WW2 Mosin? (Diabolical Build)," it is built as a first-encounter piece rather than a review: Lujan says on camera that this is a first attempt at loading the rifle, and the opening segment shows rounds going in one at a time because no stripper clips were on hand.
Most of the first half is about recoil. Shooting the Mosin unsuppressed, Lujan describes the rifle as painful and turns the camera on reddening along the shoulder between strings, returning to it as the session goes on. "I could not imagine going to war with this thing," Lujan says later, during the long-range segment.
What the Dead Air Wolverine adds to a Mosin
The Wolverine PBS-1 is Dead Air's AK-pattern can, and its published rating covers 7.62x54R, the Mosin's chambering, mounted through a 14x1 left-hand thread insert or one of several other adapters. Retail listings put it at roughly 7.4 inches with the thread adapter and about 20 to 24 ounces depending on configuration, built around a welded core of Stellite baffles inside a stainless tube. Dead Air's own published figures claim a reduction of up to 30 decibels. Lujan credits Silencer Shop as the source of the suppressor. The video does not address how the rifle's muzzle was threaded to accept it; a standard M91/30 leaves the factory without muzzle threads.
The back-pressure warning did not survive the range
Before the can goes on, Lujan relays a warning received off camera: that suppressors raise back pressure, and that the Mosin's recoil will therefore hit the shoulder harder. The video returns to that expectation twice more before the first suppressed shot. The reaction after it runs the other way. "No, that's way easier," Lujan says. "That's way more pleasant."
Published guidance from the suppressor trade points the same direction. Silencer Central and Silencer Shop both describe suppressors as producing a net reduction in felt recoil, commonly cited in the range of 20 to 40 percent depending on caliber, load and can design, because gas that would otherwise leave the muzzle at full pressure is slowed and dispersed first. The back-pressure penalty shooters complain about is largely a gas-gun problem: more gas driven back through the port makes a semi-automatic action cycle harder and faster. A bolt-action Mosin has no gas system for it to act on.
An iron-sight run out to 500 yards
The range segment becomes an accuracy problem the video did not set out to run. Lujan starts low on the 150-yard plate, then finds the tangent rear sight still on its lowest setting and moves it up. The first hit lands only after the suppressor, which had worked loose on the way to the long-range bay, is tightened down. The 300-yard plate falls with a hold of roughly one target high. The 500-yard plate takes the sight ladder set to 700 before it rings.
“The back-pressure penalty shooters complain about is largely a gas-gun problem, and a bolt-action Mosin has no gas system for it to act on.”
Tess Marlowe, The ReticleThat last detail is the rifle's sights working as designed. The M91/30's tangent rear sight is graduated in meters, from 100 out to 2,000, so a shooter reading those numbers as yards will land low at every setting. Lujan also says on camera that the bullet weight in the cartridges being fired is unknown; the bench frames show a box of Sellier and Bellot rifle ammunition.
No measuring instrument appears at any point. Asked how loudness is quantified, Lujan asks whether a decibel meter is on hand and, told it is not, settles for judging by ear. The video makes no sound claim beyond that.
Two sponsor reads inside one range day
The video carries Sonoran Desert Institute as title sponsor, with a read placed between the recoil segment and the long-range segment covering the school's online firearms technology and uncrewed technology programs. Silencer Shop gets a second, shorter credit delivered as an acknowledged pickup, which Lujan opens as "Lujan from the future" after realizing the attribution had been left out of the original shoot. Both reads stay in the cut as recorded.
The video closes by naming what it turned into. "That video was not supposed to be like a marksmanship challenge," Lujan says over the final frames, "but it kind of became one."
For context
- The Mosin-Nagant M91/30 is a bolt-action rifle chambered in 7.62x54R, fed from the top by five-round stripper clips.
- Its tangent rear sight is graduated in meters rather than yards, from 100 out to 2,000.
- The Dead Air Wolverine PBS-1 is an AK-pattern suppressor whose published rating covers 7.62x54R, mounted via a 14x1 left-hand thread insert or an adapter.
- Back pressure principally affects gas-operated actions, which cycle harder when more gas is driven back through the port; a manually worked bolt action is not cycled by gas.
