Aero Concept System
Features of AeroPoint
AeroPoint™ (US Pat.) takes arrow performance to an all new level as the AeroPoint will align itself concentrically to one's arrow once it is assembled. AeroPoint is also virtually effortless to install as a result of our patented Double O-rings System / FACT Technology.
Most archers know that it is difficult to align the field point/broadhead to the arrow perfectly as the neck and threads of the field point could not be concentrically aligned with the arrow insert as well as the arrow. What archers could expect was that the field point would hopefully align well enough to make the arrow fly with acceptable accuracy. AeroPoint™ (US Pat.) solved the above problem as AeroPoint will align itself concentrically to your arrow once it is assembled and takes your arrow performance to an all new level. Furthermore, AeroPoint is virtually effortless to install and will lock tight on your arrow even after continuous shooting as a result of our patented Double O-rings System / FACT Technology.
Features of AeroInsert-A
AeroInsert-A are featured with Self Concentric Technology and Reverse Tapered End Collar Technology which these technologies take arrow performance to a new level. The beauty of Reverse Tapered End Collar (i.e. angled collar on the back of the insert) is that it forces the arrow to mate with AIA and instantly self concentric itself to the arrow. Furthermore, Reverse Tapered End Collar can protect and strengthen the arrow front to prevent mushrooming effect. The insert end of AIA is purposely indented to provide large gluing surface to improve strength and stability.
AeroInsert-A Arrow Chamfering Tool
AeroInsert-A Arrow Chamfering Tool [AIAACT] helps you to quickly prepare a perfect 45 degree chamfered arrow end to perfectly mate with the Reverse Tapered End Collar of AeroInsert-AA or AS. Chamfering Tool is made of steel and the grounding surface is diamond electroplated. With these high specifications, it is only US$29.95 per pc. Chamfering Tool is extremely easy to use and easy to clean. Just attach it to any drill, insert and align your arrow into the center of the tool and run the drill (~1500 rpm) for approximately 3 seconds and your perfect 45 degree chamfer is prepared and you are ready to glue your arrow insert into the arrow. The tool is dishwasher safe, so just wash, dry, and it is ready to be used again.

Features of AeroInsert-D
AeroInsert-D is designed to fit most arrow sizes. Similar to Aeroinsert-AS/AA, Aeroinsert-D is featured with Self Concentric Technology and Reverse Tapered End Collar Technology. In addition to these technologies, AeroInsert-D insert has dual step design to provide extra large adhesive area and is ready for Hybrid Insert System. Extra large adhesive area is important as common insert only has small adhesive surface which causing the insert easy to dislodge from the arrow and consequently forcing the insert and arrow tip to move rearward into the arrow shaft and finally causing the front end of the arrow shaft to mushroom.
The insert dislodgement and mushing effect issues are intensified especially while you are using 0.300” ID weak spine crossbow bolts. To solve this issue, Double Shoulder Insert System was developed (i.e. AeroInsert-D installed with carbon extension). AeroInsert-D Systems can strengthen the arrow as adhesive surface is increased and the wall thickness of arrow front end is increased without adding much weight. Furthermore, precise adjustment of arrow weight can be done via adjusting the length of the carbon extension (i.e. a longer extension gives greater weight, and a shorter extension gives lighter weight). However, in order to make Hybrid Insert System works as described, the use of right glue is important. Thus Firenock has formulated a 2 part slow set epoxy, Aerovane Epoxy.
An example to explain the advantage of AID and AeroConcept System: An arrow installed with a 45 grain field point in Stainless, an AeroInsert AID31A (22 grain) with a 6 inch of carbon extension (6 x 5.92 grain per inch =35.52 grain) can make your arrow fly like an arrow with a 100 grain glue in point! What more can you ask for?
As AeroInsert-D has a number of model, they are coded as follows: the first 3 characters " AID" stands for AeroInsert-D, the next 2 number stands for the class size of the arrow it will fit (e.g. 30 = 0.300"), the last character stands for material it is made of (A=Aluminum, S=Stainless).

Features of AeroInsert-H
Features of AeroOutsert
Another issue for common inserts is that they suffered from a perimeter wedging effect (i.e. hard to pull the arrow out from the target). The AeroOutsert Blood Channel was designed to minimize this effect which this feature again outperformed common inserts. AThe Blood Channel is a plurality of axial slots which are machined over the outer perimeter of the AeroOutsert and these axial slots gradually taper inward towards the center line of the AeroOutsert. The Blood Channel can relieve the pressure built up over the outer perimeter of the arrow, thus reducing wedging effect. AIn other words, Blood Channel allows you to pull the arrow out from a penetrated object easily and Blood Channel not only reduces weight but increases strength and improves ease of use. Below is the technical drawing of an AeroOutsert, front end of arrow shaft, and a field point in exposed view with exact dimensions (Outlined in blue is the AeroOutsert).
Tips and Tricks on AeroOutsert™ Installation
Tips and Tricks on AeroOutsert™ Installation
Some customers may have problem while installing AeroOutsert on their arrows even they have bought the right size of AeroOutsert for their arrows. This is generally due to the fact that true outside diameter of arrows may be different from the manufacturer published specifications, thus published arrow OD sizes are only for reference.
Case in point, the Victory VAP is published as 0.245" OD but the actual measurement is 0.248" which means it will actually fit the 6.31mm/0.248” AeroOutsert best, not 6.22mm/0.245”. In the case of the Easton Injexion 480, within a dozen arrows tested and measured, their OD can vary from 5.836mm to as large as 5.864mm; which made 5.83mm the correct size. One way you can overcome this issue is that you can sand your shaft to get the right outer diameter. If so, we suggest to use ultra fine sand paper (220 grid or finer) and sands the shaft in a circular fashion, the shaft concentricity should not be off after sanding. After sanding, dip the sanded shaft end in pure acetone and then clean the inside of the AeroOutsert using Q-tips with acetone. Acetone is proven to be the best cleaning agent for installation of AeroOutsert before gluing. For ultra tight fit and fast installation, any fresh CA type glue (super glue) should work well. If AeroOustsert is slightly loose to fit your arrow, you can use slow set epoxy and keep turning it with the arrow standing up which this should keep the AeroOutsert concentric to the arrow. One should keep the arrow upright to ensure the AeroOutsert is concentric to the shaft while the glue is curing. If the arrow is laid horizontally while using slow set epoxy, the shaft will no longer be concentric.
AeroOutsert is available to fit these arrow outer diameters (5.68, 5.77, 5.83, 5.89, 5.97, 6.06, 6.12, 6.15, 6.22, 6.26, 6.31, 6.33, and 6.50 mm) and weighed from 30.5 to 33 +/- 0.5 grain (larger diameter, lighter weight will be). Below is a table showing the outside diameter of most common 0.165" - 0.1665" ID shafts and the corresponding AeroOutserts that would fit. Please note that the sizes shown are for reference only, actual OD of arrow can vary and experience has shown that it can vary significantly even among a single dozen. The only sure way is to actually measure your shafts before ordering your AeroOutserts or locate a Firenock Authorized dealer who can install them for you as the dealer should have all sizes of AeroOutserts in stock. Authorized Firenock dealers also have the experience to deal with the size variance of the arrows.

Features of AeroBushing
AeroBushing™ is loaded with the Self Concentric System, Square in a Circle Fitting Technology, and Reverse Tapered End Collar Technology to address the need for ultra lightweight and consistent archery projectiles on the nock side. Traditionally uni-bushings are made from bar stock and manufactured on screw machines which will only provide approximate fit. Commonly, target archer will use material like a plastic bag to shim fit the bushing and insert a nock in it to provide a good fit, however this approach cannot ensure accuracy and consistence. Not to mention the standard weight of the uni-bushing and nock system usually weighs between 20-25 grain. The AeroBushing utilizes the same approach of the Firenock compression fit system but does it in a reverse way. Instead of a round collar, AeroBushing is actually square in shape. The square shape will force the arrow to be concentric with the bushing. Re accuracy, AeroBushing is CNC machined, thus ensuring nock and arrow will be concentric with the AeroBushing. The square shape also resulted in lighter weight; a normal bushing of 23/64" size is about 12 grain vs AeroBushing is just about 8 grain. AeroBushing is not using standard uni-bushing nocks for 23/64 size. AeroBushing utilizes the Firenock A style nock which is 0.204" ID as Firenock believes that the A style nock is the most ideal nock for target archery. FYI, the Firenock A style nock is only 4.85 grain, which it is lighter than most 0.166" ID nocks and it has the most advanced nock throat designed by Firenock. Firenock A style nock is accurately made, can self concentric itself once installed (no glue is needed), and made of German material. Finally, the weight of entire AeroBushing with the Firenock A style nock is only about 13 grain. Starting from 2015, the AeroBushing is also equipped with our US Patent Umbrella-Cap design. This new design virtually eliminates the possibility of carbon fiber to fray even if the back of an arrow is being hit by another arrow. The details of this design can be seen in the technical illustration of ABU23A.
Aero Concept Target System
Firenock offers a complete AeroConcept System for 4 class arrows, 0.202", 0.244", 0.300", and 0.310" ID respectivaly. AeroConcept System includes the Firenock AeroInsert-D/H , Carbon Tube for AeroInsert-A/H, AeroPoint, AeroBushing, and Firenock polycabronate nocks.
For 0.300" ID arrows, one can use our V nock at the back, Firenock AID30A, CTAI22, and an AeroPoint 45 grain, 9 mm in Titanium. With this set up, the front end of the arrow is substantially stiffened and strengthened with no weight penalty and the components are all concentric to the arrow. Since the AeroPoint is removable, one can replace the point at any time. Furthermore, the AeroPoint is equipped with our patented Self Concentric Technology which makes it ideal for extreme target shooting.
For 0.315” ID arrows, one can utilize our new AeroBushing system which weighs about 12 grain (bushing and nock together). The Firenock A nock is only about 5 grain and has the best nock throat design. The photos below show the components of the Aero Concept Target System for target arrows and its weight for reference.
