If you run an air rifle in .177 or .22 and you are after a moderator that is light, slim and genuinely good looking, the Airgun Moderator Mini Magna AT 177 – 22 1/2-20 UNF Carbon Fibre 180mm (S72) 037 from Ballistic Designs deserves a spot on your shortlist. It is 3D printed in the UK, cut to a 1/2-20 UNF thread, and at 180mm long it keeps a low, slim profile on the muzzle without turning your rifle into a club.
What You Get
The Mini Magna AT is a straight, uniform-diameter moderator with a clean matte dark finish and a carbon fibre look that suits modern tactical air rifles beautifully. There are no gimmicks on the outside: no fake ports, no bolt-on wings, just a neat cylinder with a threaded bore at one end and a capped face at the other. The fine 3D-printed layer lines give it an honest, made-in-the-workshop character rather than a mass-produced shine, and every unit is printed to order by Ballistic Designs and its partners.
Build and Fitment
Fitment is simple: the internal thread screws straight onto a 1/2-20 UNF muzzle, which covers most modern .177 and .22 air rifles and carbines. At 180mm the moderator is long enough to do its job properly while staying slim enough not to snag on slings, gun bags or when you are slipping the rifle into a gun slip. The printed polymer body keeps weight low, so your point of balance barely shifts, which matters for standing shots and field target work.
Performance
In use, the Mini Magna AT does exactly what a good airgun moderator should do: it takes the sharp crack out of the shot and turns it into a dull thud, which keeps the neighbours happy and spares the wildlife on your permission. Because it is a full-length can rather than a stub, the suppression is consistent across the full power range of sub-12 ft-lb airguns. Zeroing at the club or plinking in the garden gets noticeably quieter, and the slender body keeps your sight picture clean.
Who It Is For
This is a moderator for the airgun shooter who wants a tidy, lightweight and affordable can for a 1/2-20 UNF threaded .177 or .22 rifle. It is equally at home on a hunting setup, a plinker or a range gun, and because it is 3D printed you are supporting small-scale British manufacturing rather than a faceless import. As with all airgun accessories, buyers must be 18 or over and sale is subject to the usual UK law under the Violent Crime Reduction Act 2006 framework. Used responsibly on legal airguns, it is a compliance-friendly way to make your shooting quieter and more considerate. No hunting or pest control claims are being made here, just build quality, fit and value.
Verdict
For £31.99 the Mini Magna AT carbon fibre look moderator is one of the best-value ways to quieten a threaded air rifle. It looks sharp, fits a common thread, weighs almost nothing and does its job.
