IWA 2019: The ultra-light INCA silencer from FBT Fine Ballistic Tools - Made in Austria
The small & lightweight super silencer (silencer / suppressor) "INCA" for hunting from the FBT Fine Ballistic Tools GmbH
Test report with BERGARA follows
To the video test shooting
Preliminary info: The name INCA - THE LIGHTNESS OF SILENCE - is derived from INtegrated CArbon Silencer. And another thing - according to FBT eliminated which especially Large interior surface area the RUNNINGunfortunately always occurring, especially when hunting, "First-shot effect".
When we visited the IWA 2019, our main focus was on the question of what's NEW at the Development of silencers, also Silencer or suppressor called.
For Austrian hunters this is an important issue. Since 1 January 2019, silencers have been completely free for hunting licence holders under the Weapons Act in Austria.
The legislator has positive characteristics for the sensitive ears (hearing damage) obviously recognised - and that's a good thing.
Limitation of interest of silencers for hunting use
There are many manufacturers who Silencer StructureThe different types of DDoptics binoculars Binoculars can be divided into two main types according to their basic construction: Construction with roof prism (different types of construction) or with Porro prism. Both designs have their unique advantages and disadvantages. In principle, Porro and roof prism binoculars can offer the same performance depending on the type of glass (BAK 4, crown glass, etc.), the amount of coating required and the manufacturing quality. The details decide whether they are good binoculars or not. " More info here focussing on high shot sequencest - e.g. use on an AR 15 assault rifle or other self-loaders with high firepower.

These Extremely resilient constructions are very sturdily built - which also Silencer weight and sometimes very expensive.
For Hunting applications is a Silencer with low weight interesting. Low weight means Less change in the running oscillation and thus less change in the Meeting point location. And something else is of great interest: LOW CLEANING EFFORT
Based on our preliminary research on the Internet, we were particularly interested in the compact silencer from freyr & devik with 270 g and from aimSport with a diameter of 42 mm and a weight of 340 g. The two products are convincing - unfortunately they have their weight - but after shooting you have to Open (are 2-part) and the Clean threadso that the thread does not "eat together" (not good) and they are no longer separable.
The surprise came by chance: INCA silencer - ONLY 32 mm diameter & ONLY 100 or 185 grams weight ??
If you use the FBT silencer INCA the first time you hold it in your hand, you'll be stunned - the thing isltralight and small. When you see the cross-section of the damper, you immediately think of the Patented in 1908 Maxim silencer

Design and construction of the FBT INCA silencer
The FBT INCA silencer does indeed open up a new horizon in the world of hunting silencers. The Low weightwhich Small size and No cleaning effort make up the basic concept of the INCA.
The elegant Design with carbon and the technical data on the inside make this silencer the Miracle device, that he is.
Some important information about the design and construction:
- The pressurised body is a body that is under pressure. 3D printed aluminium body, which has no seams or screws and No combination of different metals used inside. This makes it Particularly corrosion-resistant.
- To achieve this High-strength aluminium (Scalmalloy) to be able to print in the 3-D process at all, however, requires in-depth expertise in manufacturing technology. FBT is therefore working with a strategic partner from Bavaria in this area. The manufacturing technology and the material originate from the aviation industry.
- The "pressurised body" is fully functional without a carbon sleeve, although not as quiet. Hence the name INCA (INtegrated CArbon silencer)
The wall thicknesses of the FBT Ultralight silencer
Due to the low weight Let's just call him that.
The Wall thicknesses and the geometric internal structure are designed by FBT in such a way that the silencer offers the shooter the best possible protection in every situation. Full security offers.
From the FBT developers was constructively analysed every case of Splintering or fractional spreading to the rear in the event of an emergency.
Should it come to a Contact with the projectile with the interior of the silencer due to incorrect use, then the sliding columns do not pose any risk. The internal geometry of the silencer is not damaged and fragmentation of the projectile is completely prevented.
Operating principle of the FBT INCA silencer
With regard to the operating principle of the silencer, it should be noted that a basic distinction is made between Two types of silencers must be distinguished.
- The first type are the simple but of course very effective "volume silencers",
which with simple expansion volume work. However, you will need a Very large design to achieve this volume. Examples include devices from Hausken, freyr& devic, Aim-Sport, ASE ULTRA or the Optima devices from A-tec. - The second type is "gas flow or sound propagation controlling devices", under which the INCA falls
The INCA manages the Sound waves or the Supersonic gas flow in so-called "Dead run caverns" (presumably based on the Maxim principle) which have a very small internal volume but a Very large surface area have. The large and rough surface acts as a gas flow brake and cooling surface. The large surface thus eliminates the annoying "first-shot effect" that unfortunately always occurs when hunting
Calibre options for the FBT INCA Mini silencer
And now we call the Silencer even MINIPocket binoculars, often referred to as mini binoculars or pocket binoculars, are usually binoculars of the smallest design. " More info - because the diameter is incredibly small in relation to the usable cartridges.
The INCA silencer has, with the exception of the calibre diameter, No cartridge limit. This means that a cal. .30 INCA silencer can even be loaded up to a .300 NormaMagnum or .300 RUM.
The FBT available calibre groups are .30 (5.6 mm to 7.62 mm), .38 (8 mm to 8.6 mm) and 10.3 (9.3 mm-10.3 mm) - a hammer - or not?
Cleaning effort for the FBT INCA silencer - a NO GO for Fine Ballistic Tools
The Cleaning is - as explained at the beginning - a Very important topic when hunting with silencers.
Fact: The INCA cleans its surfaces itself, as all surfaces are actively aerated.
Only the Through hole should, as with any silencer, be as Clean and oiled are held. This prevents corrosion caused by powder residue. The brush supplied by FBT is used to apply a light film of oil to the through-hole; this "maintenance method to extend the service life" is generally recommended for every silencer.
