AERO System (The Perfect Approach to Prep/Build an Arrow)
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.
In the past, achievement of perfect alignment of the target point/broadhead to the arrow was not easy as the neck and threads of the point may not be concentrically aligned with the arrow insert as well as the arrow. What archers could expect was that the target point would hopefully align well enough to make the arrow fly with acceptable accuracy. More recently, a single O-ring was installed on the neck of some broadheads to improve the concentricity issue. Though this single O-ring design helped to improve the alignment of the broadhead blades to the arrow and vanes, it did not completely solve the issue of concentricity of the arrow.
Features of AeroInsert-A
The special features of AeroInsert-A(AIA) are Self Concentric Technology and Reverse Tapered End Technology which will take the performance of arrows to a new level. AIA is CNC machined to ensure precision and made of 7075-T5 Aluminum and hard anodized to ensure durability. AeroInsert –A is also laser marked with the Firenock brand. The collar of AIA is Reverse Tapered End designed (i.e. angled collar on the back of the insert) which will force the arrow to mate with it and instantly self concentric the insert to the arrow. Furthermore, the AeroInsert-A Reverse Tapered End collar can protect and strengthen the arrow front to prevent the mushrooming effect. The insert end of AeroInsert-A has a large gluing surface to improve strength and stability.

Features of AeroInsert-D
Why Firenock made AeroInsert-D? Common mid size arrow insert has an issue, the neck of the target point and its threads might be off concentric from the arrow insert. In the past, target archers could only hope that target point would align well enough with the insert to make the arrow fly with acceptable accuracy. Furthermore, common inserts are poor in tolerance, thus it is nearly impossible to ensure target point as well as insert is concentric to the arrow point, and thus consistent accurate arrow flight. In addition to these issues, most common inserts are short in length which this does not provide enough adhesive surface to provide good security and strength. As a result of having a small adhesive surface, it is common for the insert to come dislodged from the arrow, thus forcing the insert and arrow tip to move rearward into the arrow shaft and consequently causing the front end of the arrow shaft to mushroom. AeroInsert-D has many model. To understand the model numbering system of AeroInsert is simple. The first 3 characters are" AID" which stands for AeroInsert-D. The next 2 number are the class size of the arrow it will fit; (30 = 0.300"). The last characters stands for material it is made of (A=Aluminum, S=Stainless). Different material is utilized in order to address different strength and kinetic requirement for archery projectile. AeroInsert-D takes arrow performance to a new level, by simultaneously self concentric itself (US patented) and strengthen the arrow front end itself but without adding weight.
The above issues are further intensive for high powered crossbows while using the 0.300” ID weak spine crossbow bolts. To solve these issues, one can increase the wall thickness of the entire arrow shaft, but this will add a lot of weight to the arrow, thus decreasing performance of the arrow. Recently, there are developments in addressing the issue of spine stiffness; one uses a tapered shaft (i.e. larger at the front than at the rear), and another claims to achieve a dual spine design by changing the wrapping sequence of the composite, these new arrows however still have issue due to common inserts have tolerance and strength issues. AeroInsert-D solves the tolerance and strength issues as AeroInsert-D is precision made and its dual step design increases adhesive surface area and self concentric itself to the arrow once it is assembled. In short, AeroInsert-D increases arrow accuracy in terms of concentricity, strength and durability.
To make AeroInsert one step better, AeroInsert-D installed with Firenock carbon extension to form hybrid insert system which this further strengthens the arrow as adhesive surface is increased, the wall thickness of arrow front end is increased but without adding much weight. Precise adjustment of arrow weight can be done via adjusting the length of the carbon extension. In general, a longer extension results greater weight, and a shorter extension results lighter weight. (Note: The magic of Hybrid-Insert system is only made possible with the use of right glue which Firenock will provide this glue for sale very soon or please contact Firenock for details).
AID31A is specifically designed to fit shafts like the Black Eagle Challenger, PS23, Carbon Express CXL and Easton FatBoy. AID31A must be used with carbon extension (i.e. a hybrid insert system) to achieve best result. FYI, the carbon extension is only 5.92 grain per inch. Thus for an example, an arrow installed with a 45 grain field point, an AeroInsert AID31A (20 grain) and 6 inch of carbon extension (6 x 5.92=35.52 grain) can result like an arrow with a 100 grain glue in point!

Tips and Tricks on AeroOutsert™ Installation
Some customers may face installation issues while trying to PERFECTLY fit an AeroOutsert into their arrows. An outsert system needs to fit the outside diameter of an arrow as perfect as possible. However, most arrows’ true outside diameter may be different from the manufacturer’s published specifications, thus published 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 AeroOutsert best, not 0.245"/6.22mm. 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. However, one can always make the shaft smaller by light circular sanding.
After extensive testing we have determined the best way to install an outsert system into your arrow is to get the right size of AeroOutsert in respect to the published manufacturer specifications, but you need to dry fit the AeroOutsert into every arrow. In some cases, a shaft may be difficult to fit or be too tight to fit the AeroOutsert. Slight circular sanding of the outside diameter of the shaft will solve the issue. As long as one uses the 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 what is found to be the best cleaning agent for any AeroOutsert before gluing. For ultra tight fit and fast installation, any fresh CA type glue (super glue) should work well. For loose fit installation, one can use slow set epoxy and keep turning it with the arrow standing up which will help 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 now available in 13 sizes (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 weight 30.5 to 33 +/- 0.5 grain depending on size. As the diameter gets larger, the weight of the AeroOutsert will be lighter. AeroOutserts are anodized in black with their size and the Firenock brand laser marked on the AeroOutsert for clear identification and great looks.
Below is a table showing the outside diameter of most common 0.165" - 0.1665" ID shafts and the corresponding OD of AeroOutserts that would fit. Please note that the sizes shown are for reference only, actual size of arrow OD 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 or locate a Firenock Authorized dealer who can install them for you as they should have all sizes of AeroOutserts in stock. Authorized Firenock dealers also have the experience to deal with the size variance of the arrows.

Aero Concept Target System
Firenock offers a complete AeroConcept Target System for 0.300" and 0.310" ID class target arrows. The whole system for these specific arrows includes the Firenock AeroInsert-D, carbon extension, and “V” style nock / AeroBushing with “A” style nock.
For 0.300" ID arrows, one can use our V nock at the back, our carbon extension (0.246" ID and 0.298” OD), Firenock AeroInsert-D30A, and an AeroPoint 45 grain 9 mm. With this set up, the front end of the arrow is substantially stiffened and strengthened with no weight penalty and the Aero System 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 System which makes it ideal for extreme target shooting.
For 0.310” ID arrows, besides the carbon extension, one can utilize our new AeroBushing system which weighs about 12 grains (bushing and nock together). The Firenock A nock is only about 5 grains 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.
