Hunters looking to get the highest possible penetration and take-down capability are choosing to use arrows that have a smaller diameter. Also referred to as micro, ultra-micro or nano-diameter arrows, depending on the size and on the company making them, they have a shaft diameter of 4 to 5mm.

Not only do small diameter arrows fly fast but their streamlined profile means that they exhibit greater accuracy too. Their smaller dimensions usually make them lighter and, when the broadhead is added, they have a greater forward of center weight to improve their penetration potential.

We have examined an array of arrows and have compiled a list of the best micro diameter hunting arrows available on the market today. They are listed together in the table directly below to give you an opportunity to compare their basic specifications. Further down the page is a more complete review of each product along with the opportunity to buy any arrows listed.

Below is a more detailed review of each make and model including all of the available sizes, their spine, weight and the outside diameter of each shaft. As you will see, there are many different options to choose from within each make/model.

We have also provided you with a little information about the inserts that are recommended by the arrow manufacturer that will best fit each shaft.

The AXIS arrows have been proven to be extremely effective in use for hunting big game. The micro profile helps to focus kinetic energy into a very small frontal area. This means less friction and greater penetration.

The arrows have a small profile and this helps them to fly very well in crosswinds, much better than arrows with a standard diameter. According to Easton Archery, the AXIS provides 24% more Kinetic Energy Density than standard diameter carbon arrows.

The arrow is available in 7 size options from 700 to 260. The straightness is +/-.003-weight and is spine matched for top level accuracy.

This is another micro-diameter shaft, measuring 4mm, that has been equipped with Deep Six nocks and steel HIT inserts.

The small diameter enhances the flight and accuracy and the high-strength carbon core wrapped in a 7075 alloy metal jacket means that it is also a durable, hard hitting arrow that will penetrate deeply.

The shafts are made with a weight tolerance of +/- 2 grains and a straightness tolerance of +/- .002". They are considered among the most advanced arrow designs available.

The FMJ Injexion is available in one of 4 sizes from 460 to 280.

The VAP Hunting arrows have been designed as the ultimate in micro diameter hunting arrows that are notable for their durability. The design reduces air friction to ensure that they fly straight and true and uses extreme front of centre weighted to enhance penetration.

Technology that has been incorporated into the VAP include MaxxKE technology which is a 3K carbon weave for less torque, digital spine alignment, ICE Nano Ceramic Coating to improve penetration. They have also been built using a Matched Weight process so that each dozen falls within +/- 0.5 grains to offer greater consistency.

These arrows are part of Victory’s .166 Series using high modulus 100% carbon fiber construction for maximum speed and penetration with less wind deflection.

The VAP is available in either the VAP Elite, VAP Gamer or VAP Sport models differentiated by their straightness tolerances. The Elite has a tolerance of +/- .001”, the Gamer has a tolerance of +/- .003” and the Sport has a tolerance of +/- .006”.

This is a hunting arrow that has been specifically designed to provide good penetration and fast speed through its reduced diameter. 

The spine size ranges from 0.500” to 0.250” and in all cases the micro-diameter shafts ensure wind drift is reduced and flight speeds are at their peak.

Included at the end of the shaft is the company’s patent pending Ballistic Collar Insert System which gives it enormous hitting power, so much so that the 340 or 300 sizes provide the perfect basis for a reliable big game arrow.

The arrows have an advertised straightness of .0025” and a weight tolerance of +/-.5 grain.

They are available in packs of 6 starting from $114.99 or packs of 12 starting from $189.99.

When you buy these arrows they come with the GTO Nock and Collar, the Ballistic Collar which is spine specific and .166 aluminum inserts.

Insert Recommended

Although the diameter of the arrows you choose is a significant factor in the way they fly, hit and penetrate, there are obviously other factors that you should consider too.

As can be seen from the lists supplied above, factors such as the arrow spine, the weight and some more obscure factors such as front of center are going to have an effect on how you shoot.

Deciding to use small diameter arrows is a good step towards equipping yourself with serious stopping power. Use them in practice, try them with a variety of fletching and broadhead combinations and come up with a set-up that you feel comfortable with.

Thanks to the high quality of research and design that goes on at each of the top arrow manufacturers you can be confident that any of the arrows mentioned on this page will give you a quality product to become more familiar with.
