About Us

Kaimai Rifle Suppressors are manufactured by D.F Maisey Ltd – the company of Tauranga-based qualified gunsmith, Dean Maisey.  With his gunsmithing business established in August 1997, and after spending time overseas and qualifying as a gunsmith (while on an International Student Visa) with Colorado School of Trades – the internationally renown gunsmithing school in Denver, Colorado (USA) – he has spent over two decades of full-time service to the firearms industry in New Zealand.  The business has produced a range of muzzle brakes and other firearms parts and accessories, as well as branching into production of high-quality rifle suppressors as well. He holds numerous design registrations, trademarks, and also a patent, on some of the items that he has designed. (Previous work experience involves a background in mechanical engineering and design, and he also completed a trade apprenticeship as an electrical and refrigeration technician.) Having been there for his customer base all the way through the highs and lows of the firearms and hunting industries over the past few decades, and spent countless hours doing volunteer work for NZDA and other advocacy groups, D.F. Maisey Gunsmithing is recognised as one of the top service providers for high-quality gunsmithing work and smaller-scale firearms-related manufacturing in New Zealand. 

Kaimai® Custom Rifle Suppressors have been designed in consultation with gunsmiths and firearms experts from NZ, Europe and the USA. We have used advances in engineering design and manufacturing from related industries, to produce a range of rifle suppressors that are not only relatively light weight, but durable and very effective at doing their main task – to reduce gunshot sound signature. Having learned from others mistakes, our intention was to overcome some of the design flaws or shortcomings of some common suppressor designs on the market.  

By incorporating high strength aircraft / weapons grade alloys like 7075-T6, Tennalum® 7068 & Titanium (imported from Europe and the USA), along with high quality stainless steel where required in the critical wear and high-temp areas, we have produced very effective and durable suppressors for sporting rifle use that are about 50-66% of the weight of comparable all-steel or stainless-steel units. Further, Kaimai® -Hybrid™ suppressors are designed to give a much longer service life compared with some competitors very lightly constructed ‘aluminium-only’ units.

While suppressor weight is a consideration, it should not be the main feature if it comes at a drastic reduction in performance levels, durability, or safety. Making a quality suppressor is a compromise between weight, unit size & length, suppression performance, recoil reduction performance, strength & durability, safe function and accuracy, and cost of manufacture. Which ultimately leads to the final consideration – price.

There is no one perfect suppressor for all applications – the user must determine the product which encompasses the best mix of features to suit their main intended use or application. The reality is that in most cases, ‘lightest’ or ‘cheapest’ does not equal ‘best’. There is plenty of evidence of prematurely-failed suppressor products on the market now to validate this point.

Of further concern is that feather-weight centerfire suppressors can heat up very quickly (creating mirage issues through the sighting plane) and may also fall well short of providing any adequate level of sound suppression at all. The test readings of some centerfire suppressors on the market have been shown to still exhibit higher than ideal sound pressure levels (peak SPL, in decibels) in comparison tests. This point must not be overlooked if one of your main reasons for purchasing a suppressor is to help protect the hearing of your dog, or other people who may be joining you on your hunt. Assuming that all suppressors work ‘pretty much about the same’ and are made to the same quality and performance standards, is a fallacy. Simply stated, in a largely unregulated firearms/suppressor industry, all suppressors are not created equal.

Kaimai® centerfire suppressors are very competitively priced, as well as being very high quality and accuracy-enhancing units. The semi-modular design, makes it possible for us to manufacture small to medium production runs of individual components and then assemble the suppressors to order as required, with the calibre-specific baffles (or ‘baffle monocore’) and a threaded internal stainless steel muzzle/diffuser brake, to meet the customer’s request. As the Kaimai Hybrid centerfire suppressors are so robust and durable (due to the addition of stainless steel in critical areas), they are not designed to be dismantled for maintenance by the end-user. There is basically no need, as there are no ongoing requirements to regularly purchase and replace eroded or shot-out baffles, which can be an issue on some other lighter/cheaper alloy suppressors. 

(The new Gen2 series centrefire suppressors do have a user-replacement front module though, so that a module that is longer or shorter – or for a different calibre – may be installed onto the main/rear module if required.)

Kaimai® ‘Monocore’ and ‘Varminter’ rimfire model suppressors are able to be easily dismantled for cleaning by the end-user.

Some of the main features of Kaimai® -Hybrid™ Suppressors

  • Improved internal isolator tube design (on centerfires models only) –  Both ends of the isolator tube are threaded – unlike some competitors only push-fit o-ring, or glued joins on the tube ends.  Exhaustive testing including with magnum calibres without any Loctite on joins, showed no leaking. 
  • Self-tightening muzzle/diffuser brake design
    • No need to over-tighten the suppressor, just light finger & thumb pressure tightened onto the thread shoulder is enough. Each shot keeps the thread fit slightly tight against the thread shoulder on a barrel with conventional RH thread. This is also accuracy enhancing, because the suppressor won’t ‘shoot loose’ and suddenly change the barrel harmonics.
    • Muzzle/diffuser brake is directly attached to barrel threads, and this diverts and re-directs about 70%-80% of the initial gas blast forces. This significantly reduces or eliminates the tendency for tube-stretching that is a design weakness of some competitors brake-less suppressor designs.
  • Improved service life over aluminium-only units
    • Calibre-specific stainless steel components utilised all the way through the ‘hot zone’ of the suppressor prevents premature wear. (Some competitors alloy-only baffles or core-faces soon wear through the anodising layer, and after that will chew-out relatively quickly with normal use.)
    • All internal and external 7000 series aluminium alloy parts are type-3 anodised, for maximum durability and corrosion resistance.
  • Exhaustive testing regime to prove the designs
  • Warrantied to be free of defects in material or workmanships
    • Consumer Guarantees Act rights for the purchaser.
    • Limited Lifetime warranty (conditions apply)
  • Highest quality
    • Our goal is to produce an outstanding product, with advanced design and technological advantages, at a reasonable price. This does not necessarily mean ‘cheap’, because there are always extra costs associated with manufacturing a better quality product. There will always be other vendors who have their place in the market based largely on lowered price point.
    • Quality, integrity, performance and reliability are our main goals.
    • NZ designed, manufactured and tested.
    • Attention to detail and perfection throughout the manufacturing process.
