Description
Some suppressors chase low weight, others chase durability, and a few go all in on sound reduction. The Sandman-L is Dead Air's answer for people who want maximum hush on a .30 cal rifle without babying their gear. At 8.9 inches long and 21.8 ounces, it pulls roughly 31dB off standard 7.62 ammo, which puts it right at the top of its class. It has been a go-to in the precision rifle world for years, and there is a reason military and law enforcement units around the globe run the Sandman series hard.
Built Like a Sandman Should Be
The baffles are Stellite (Cobalt 6), welded into a solid core that laughs at throat erosion and full-auto fire. The tube and mount are 17-4 PH stainless steel, the mount gets a Nitride treatment, and the whole can wears a black Cerakote finish for corrosion protection. Up front you get a detachable cap with an integrated flash hider, so your muzzle signature stays tame along with the noise. This one is rated up to .300 RUM with no barrel length restrictions, so everything from a short 5.56 carbine to a magnum bolt gun is fair game.
KeyMo Mounting Done Right
Quick-detach mounts have a reputation for wobble and seizing, and Dead Air's KeyMo system was designed specifically to kill both problems. You can spin the Sandman-L on or off with one hand in a few seconds, it locks up dead solid, and point of impact shift stays minimal shot after shot. The included 5/8-24 KeyMo muzzle brake gets you mounted on the most common .30 cal thread pitch right out of the box, and additional KeyMo devices let you move one can across several rifles without re-zeroing headaches.
Where the Sandman-L Earns Its Keep
DMR builds, tactical bolt guns, .308 ARs, hunting rifles chambered in 6.5 Creedmoor, anywhere you want serious sound reduction and a mount you can trust. Dead Air backs it with a lifetime warranty, which tells you how confident they are in the construction. If quiet is the priority, this is the Sandman to get.

Frequently Asked Questions
How quiet is the Dead Air Sandman-L on 7.62?
It delivers a true 31dB of sound reduction with standard 7.62 ammunition, which puts it among the quietest .30 cal suppressors made. The extra length compared to the Sandman-S and K is what buys you that performance. If maximum sound reduction is your goal in this series, the L is the one.
What calibers can I run through the Sandman-L?
It is rated up to .300 RUM, which covers just about everything below that including 5.56 NATO, .300 Blackout, 6.5 Creedmoor, .308 Win, and 7.62 NATO. It is also full-auto rated with no barrel length restrictions, so short-barreled hosts are fine. The included brake is 5/8-24, and other thread pitches just need a different KeyMo device.
Does the Sandman-L come with the mount included?
Yes, it ships with a KeyMo muzzle brake in 5/8-24, so you are ready to mount on most .30 cal barrels out of the box. If you want to run the can on multiple rifles, extra KeyMo brakes or flash hiders are sold separately. Swaps take just a few seconds with one hand.
Will the Sandman-L shift my point of impact?
The KeyMo mount was engineered specifically to eliminate the wobble and seizing that plague lesser QD systems, so point of impact shift is minimal and repeatable. It locks up solid every time you reattach it, which is why precision rifle folks trust it. You should confirm zero with the can mounted, but it holds consistent from there.
