Main Features of AeroPoint
AeroPoint™ (US Pat.) takes arrow performance to an all-new level as AeroPoint will self concentric to one's arrow once it is assembled. Besides this, AeroPoint is easy and virtually effortlessly to install as a result of US patented double O-ring system / FACT Technology.
In the past to achieve perfect alignment of target point/broadhead to arrow is 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 to fly with acceptable accuracy. More recently, a single O-ring was installed on the neck of some broadhead 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, this single O-ring design did nothing to concentricity of the arrow.
Main Features of AeroInsert-A
AeroInsert-A is offered in 2 sizes namely AeroInsert-AA and AeroInsert-AS. The AeroInsert-AA is specially made to fit smaller diameter shafts (0.202”-0.204" internal diameter, for example: Gold tip Kinetics; Easton axis arrow, any MFX, or arrows that can fit the A nock form Firenock, X nock from Easton, or Gold tip, Accutough nock S, etc). While AeroInsert-AS is specially made to fit standard size arrow that has an ID of 0.244" to 0.246" (aka S nock size) and due to its size it is neither anodized nor laser marking. AeroInsert-AA weighs 18.0 grains whereas AeroInsert-AS weighs 10.5 grains.. For those who prefer a heavier FOC, and ability to use shaft with OD as large as 7.2 mm, AeroInsert-AA is also available in Stainless Steel at ~56.5 +/-0.5gn. For technical specification of AeroInsert-A, please see below.

Tips and Tricks on AeroOutsert™ Installation
Some customers may face installation issue while trying to PERFECT fit an AeroOutsert into their arrows. Being an outsert system, it needs to fit the outside diameter of an arrow as perfect as possible. In the case of most carbon arrows, the inside diameter is the only dimension of the shaft that is controlled as it is rolled on the mandrel, therefore it is the only size that is close to accurate. The fact that most arrows are rolled, the thickness of the shaft will be determined by how much is being sand off after it is rolled and cured. Thus, the outside diameter of the arrow is usually not exact. To make matter worst, for most of this class of shaft (0.166" ID) a center less grind process is usually employed, which this may lead the published OD and the ID be inaccurate. Experience showed when installing AeroOutsert on various arrows confirmed that some of the manufacturer's published arrow OD sizes are only for reference, which their size can vary as much as 0.004" or 0.11mm. Case in point, the Victory VAP is published as 0.245" OD but actual measurement is 0.248" which it will actually fit 6.31mm AeroOutsert best, not 0.245"/6.22mm. In case of the Easton Injexion 480, within a dozen arrows that we had tested and measured, their OD can vary from 5.836mm to as large as 5.864mm; which this made 5.83mm the correct size as one can always make the shaft smaller by light circular sanding.
Base on tests that have been done, it is believed the best way to install an outsert system is firstly to get the right size of AeroOutsert for the outside diameter of your arrow, then try to dry fit AeroOutsert into every arrow. Sometimes, some shafts may be difficult to fit or be too tight to fit AeroOutsert, slight circular sanding the outside diameter of the shaft will solve the issues. 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 this will help to keep AeroOutsert concentric to the arrow. One should keep the arrow upright after one has confirmed that the AeroOutsert is concentric to the shaft via spinning and then just let the glue curing itself. If the arrow is laid horizontally while using slow set epoxy, shaft will be no longer concentric.
AeroOutsert is now available in 12 sizes (5.68, 5.77, 5.83, 5.89, 5.97, 6.06, 6.12. 6.15, 6.22, 6.31, 6.33 and 6.50 mm) and weight 30.5 to 33 +/- 1 grain respectively depending on size. The larger size / hole, the weight of the AeroOutsert will be lighter. AeroOutsert are anodized in black with their size and Firenock brand laser marked on the AeroOutsert for clear identification and great outlook.
Below is a table showing the outside diameter of most common 0.165" - 0.166" ID shafts and their corresponding OD of AeroOutsert that would fit. Please note that the sizes shown are for reference only, actual size of arrow OD can vary from production batches and experience has shown that it can vary significantly among manufacturers 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 AeroOutsert in stock, and have experience to deal with the variance.

Aero Concept Target System
Firenock offers a complete AeroConcept Target System for 22/64” and 23/65” target arrows. The whole system for these specific arrows are Firenock AeroInsert-D, carbon extension and “V” style nock / AeroBushing with “A” style nock.
For 22/64” one can use our V nock at the back, our carbon extension (0.246" ID and 0.298” OD), Firenock AeroInsert-D22A, 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. Due to AeroPoint is removable, one can replace the point any time. Furthermore, AeroPoint is equipped our US patented self concentric system which makes it ideal for extreme target usage.
For 23/64” size arrow, besides the carbon extension, one can utilize our new AeroBushing system which weighs about 12 grain (bushing and nock together). FYI, Firenock A nock is only about 5 grain and has the best nock throat design.
