Hausken MD28 MK2 .22 LR Rimfire Suppressor – Slim, Lightweight Sound Moderator for Rifle & Pistol

If you’ve been searching for a genuinely slim, no-fuss sound moderator for your .22 LR or .17 HMR, the Hausken MD28 MK2 is well worth a serious look. It’s the slimmest model in Hausken’s Mini series, and once you pick it up, that 105-gram weight really does speak for itself.

A Silencer That Stays Out of Your Way

One of the biggest gripes with fitting a sound moderator or rifle silencer to a rimfire is losing your sight picture — particularly on pistols or rifles with low-mounted open sights. Hausken have sorted this rather neatly with the MD28 MK2. At just 28 mm in diameter, it sits slim enough to clear standard open sights without any faffing about with raised mounts or new optics. Fit it and forget it.

The front-mounted design keeps the whole suppressor ahead of the muzzle at 166 mm, which also means the action stays cleaner and the balance of your rifle or pistol remains largely unchanged. For a .22 LR sound moderator, that’s a proper bonus.

Surprisingly Quiet for Something So Light

38 dB of sound reduction from a moderator weighing just 105 grams is genuinely impressive. Whether you’re out on a pest control job, knocking about on the range, or stalking rabbits on a quiet morning, the MD28 MK2 takes the sharp crack of a .22 LR or .17 HMR down to something far more manageable — for your ears and for anyone nearby.

It’s the sort of rimfire suppressor that does exactly what you need without making a song and dance about it. Solid noise reduction, sensible weight, and no compromise on handling. Hard to argue with that.

Built for British Weather

The MD28 MK2 is machined from aluminium — tough, corrosion-resistant, and perfectly happy out in the damp. Whether it’s a wet November morning on the permission or a long afternoon session at the club, this sound moderator won’t let you down. Hausken are a Norwegian outfit, so they know a thing or two about building kit that handles the cold and the wet without complaint.

Will It Fit My Rifle?

The MD28 MK2 rimfire silencer comes in two thread options — ½”-20 UNF and ½”-28 UNEF — covering the majority of popular .22 LR and .17 HMR bolt-action rifles and .22 pistols on the market. Do double-check your barrel thread before ordering, as it’s always worth being sure. Thread adaptors are available separately if needed.

The Bottom Line

If you want a rimfire sound moderator that’s slim, light, and genuinely effective — without paying over the odds or wrestling with your sights — the Hausken MD28 MK2 is a cracking choice. It’s well made, straightforward to fit, and does the job quietly. Quite literally.
