Accuracy and Barrel

Today, we will be introducing to ourselves a new and a must word for us that we will be using most of the times.
and that word is "sweet spot"

now, the sweet spot, is not too much, not too less. With this, we are pointing out, on what they call "its on the right spot" or "its just perfect".

In Airsoft, there are ALOT of us which decides to go extreme. Extreme fps, Extreme ROF and so on. That is why most of the time, we forget the important thing called BALANCE. 

In this topic. we will be talking about "sweet spot" of an AEG barrel.

There are a lot of upgrades in the market with AEG Barrels. We upgrade our barrel to increase FPS or to make our shot accurate, but there are so much of what we can choose from and we usually go to our extremities. We confuse ourselves with what inner diameter of barrel we have to buy without having the right knowledge of it.

Lets figure out the market today.
The stock barrel commonly comes in 6.08 inner diameter. Most of us think that this is too wide, that is why we want to buy tight bore and we think that it is the proper solution to it. 

The tightest barrel in the market is EdGi Barrel which is 5.98 inner diameter. WOW. thats alot of fps gain! but the truth is, it will be too tight for all the air to be stable. we have to remember that this is EXTREME, although it could be helpful, the sweet spot is not defined by extreme!

Now, while its true that the tighter the bore is, the higher the fps will gain, it does not mean that it will increase your range and accuracy. NOT MOST OF THE TIME!

In choosing the right barrel, we have to go for the "sweet spot". not too tight, not too wide. and this is where 6.05 barrels comes in.

And i will explain you why 6.05 is the best barrel you could go with.

1. Although barrel bounce in tight bore barrel is not yet concluded and proven, its always safe to ELIMINATE the risk. Barrel bounce disturbs the BB spin thus reducing its maximum FPS output, range and ultimately making your shots innacurate.

2. Most of the people argue which is better, tight bore, or wide bore. Having 6.05 puts us in the middle of 6.08(or 6.2) and 5.98(or 6.01) which leaves us in peace. nobody to argue with because we are not ONE SIDED. or simply we are on the SWEET SPOT.

3. In rules of Aerodynamics, air does go around round objects. this gives us the advantage of having air going around the BB and keeping it on the center while not losing our FPS with wide bore( specially 6.2 that would drag your fps down by 50 - 80+). 

4. If ever there are small debris on the barrel, it would not disturb the BBs as much as the 6.01, thus preventing it from jamming.

In short, we are tightening our barrel to increase our FPS yet letting it still a bit wide to let the BB spin that was created by the hop up.
Too tight might disturb the backspin of the BB.
Too wide and we might lose alot of FPS boost.

There are few conclusions that tight bores works good with CQB type barrels, and extreme long ranges works best with wider bore.
And for those who uses M4 platforms that sits on the middle of CQB and snipers, the best ones are ofcourse the 6.05s. but if you are on cqb or long ranges, you can still stick to 6.05 because of its sweet spot.
But big part of the key of your accuracy is your HOP UP. The best ones ofcourse are R-hop and Flat hop, But its not necessary that you do it. because these modifications are for pros. You can make this perform good as long as you set up your hop up right.
now, your hop up needs to work with your barrel. that is the key to accuracy.

Now we've learned about the sweet spot of our barrel and how to use the optimum of our accuracy!

Secret of FPS Efficiency

Most of the players assume that the longer the barrel, the more accurate it will be.
and most of the players thought that it would increase the fps when the barrel is longer.

These theories might have a sense, in a way that the air is still contained in the barrel instead of wasting it.

Unfortunately, theories are most of the times different than practical. Overall, the AEG gun will have to be ALIGNED to all its components to function good. and by that alignment, i mean the types of component inside. and THE KEY OF SQUEEZING OUT THE BEST FPS and range is

"CORRECT PAIRING OF BARREL LENGTH AND CYLINDER TYPE"

We have different kinds of cylinders. We have different ports and sizes, and there are specific barrel lengths that will fit according to the ports.

the reason why is this done is because we have this thing called Maximum Velocity.
We are trying to match up the air volume of the cylinder to the barrel.

Here is the chart of what we supposed to have.
this will also show us the COMMON types of cylinder, so lets take this moment to learn.



 Here is a video of actual test between shorter barrel and longer barrel.



Now, we have learned this.
we will tackle next time the secret of range and accuracy!

Updates: We will hear something next time about Ace1Arms.

M4 Gearbox

M4 Gearbox Information and Action Sequence.
This will be your apple of eden in teching airsoft; A must know for all airsoft techs.
Also, this will help you to identify which part is which.

We will be having an insight of the most common gearbox in the market.
the version 2 gearbox of M4 AEG platform.

Here we have the actual gearbox:

And here we have the labeling:

And Here is how all the action under the hood:

- Gearbox Shell:  This shell contains all the internal parts and is engineered to fit into the receivers of various electric airsoft guns.

– Bushings and/or Bearings:  These fit into holes on each side of the electric airsoft gun gearbox to allow the gears to rotate smoothly.

– Shims: These are small spacers that go between the gears and bushings, these are used to adjust the height of the gears which will reduce wobble and increase longevity and consistency of the gears.

– Motor:  The motor converts electrical energy from your battery and turns it into mechanical energy which is used to spin the gears.

– Gears:  Most electric airsoft guns use three gears, a Bevel gear which transfers the energy from the motor to the spur gear as well as keeps the gearbox for spinning back on itself by way of an anti-reversal latch.  The Spur gear is moved by the Bevel Gear and is used to turn the sector gear.  The Sector gear is responsible for moving the tappet plate back as well as pulling the piston back.

– Anti-Reversal Latch:  The anti-reversal latch is a simple piece of metal that is spring loaded to engage with the bevel gear and keep it from running backwards.

– Main Spring:  This spring is responsible for pushing the piston forward.  Airsoft springs have ratings using various systems from % to M numbers.  M stands for Meters Per Second.   Generally speaking, the higher the number the more energy the airsoft BB’s will be fired with.  Airsoft upgrade springs can be either variable, allowing a gentle pull at when the sector gear starts pulling the piston back, or a linear spring that holds the same rate through out the airsoft upgrade spring.

– Spring Guide:  The spring guide’s job is to keep the spring centered and from flexing.  This is also what your full stock or buffer tube gets bolted to on M16 rifle style airsoft guns.

– Gearbox Cylinder:  The cylinder is simply a chamber that the piston slams through to compress air.

– Cylinder Head:  The Cylinder Head is usually a piece of polycarbonate or aluminum that also has a nozzle that comes off it allowing a volume of air from the larger cylinder to be compressed through the nozzle, there by propelling the BB out of the hop up chamber.

– Piston:  Made from a variety of materials, including metal and polycarbonate, pistons have a rack of teeth on them allowing the sector gear to pull them back after the spring slams them into the cylinder.

– Piston Head:  The Piston head bolts to the piston and has a O-Ring on it to prevent air from getting past the piston.  The more air the piston pushes forward, the stronger the charge of air coming out the barrel will be.

– Tappet Plate:  The Tappet plate is pulled back by a knob on the sector gear and springs forward once released.  It’s used to hold the air nozzle on the cylinder head.

– Air Nozzle:  The air nozzle attaches to the tappet plate and slides back and forth on the nozzle sticking out of the cylinder head.  The air nozzle performs two tasks.  The first task is to slide back and forth on the cylinder head allowing one airsoft BB to ram out of the magazine into the hopup chamber.  Once done the tappet plate rams the nozzle forward into the hopup rubber creating a solid seal.  This allows transfer of all the air compressed by the piston into the cylinder head to be transfered to the back and sides of the bb, propelling it out of the barrel and down range.

– Selector Plate:  The selector plate is a piece on some gearboxes that moves forward or back when the selection switch is moved from safety to the various firing modes.

– Trigger:  The trigger assembly activates a switch that transfers power from a battery to the motor there by activating the electric airsoft gun.

now remember that even though this is a version 2 gearbox, almost all of the gearboxes
in the market functions the same way, but in different set up.

I hope that you learned how the gearbox functions and how all the parts works all together.

The 4 Horsemen

Quick defenitions of the 4 main groups of Airsoft rifles!
Hopefully you guys will have an idea which is which in this infographic I made.



We will be discussing more about types of airsoft.
 But we will be going back to basics!
M4 AEG is the next topic. Stay tuned!

First thing's first.

First thing's first; With that being said, lets go back to basics.
so, what is AIRSOFT?

Airsoft - is a gamesport in which participants eliminate opponents by hitting each other with spherical non-metallic pellets(which is known as BBs) launched via replica firearms called airsoft guns.

Big part of which we are going to talk about in this blog is Airsoft Guns.





Airsoft guns varies in many different ways. being springs, battery, and gas operated. It is divided in 4 groups in which each one of them has their unique ways of propelling the BBs yet the same way in a sense that all of them uses air.
Some of which is more complicated than the other, and some of which is easy to operate.

We will be tackling next time the 4 main airsoft gun platforms and we will have an insight of what is going on under the hood. We will have the opportunity to learn and understand what is going on behind the mechanics of the guns.

In this blog, we will talk about builds, tech tips, news, and exciting new products that may help airsofters do a step further with their airsoft guns.


Stay tuned!
