EdGI 6.01mm 435mm VSR Bull Barrel review

EdGI 6.01mm 435mm VSR Bull Barrel

 

 

 

 

Supplier

The barrel was supplied directly from EdGI himself, Communication was really easy and he understood all I asked, once my order was completed he supplied the payment details and payment was complete within 2 days.

Postage:

The item was shipped via FedEx, I was able to track its movements pretty much every step of the way. The item was shipped on Friday evening (12pm GMT) and was then shipped to China, It then took 24hours to get to Paris and by Saturday evening at 11:30pm GMT the item was in Stanstead airport. Item then was delivered at 9am GMT on Monday morning. One week later after receiving the items, I received a letter demanding £13 in custom charges

Packaging:
Item was supplied in a FedEx shipping envelope. Inside this I could feel a nice sturdy tube. I put the barrels down on the bed and noticed a chink of the two barrels I had ordered meeting together. This put a smile on my face as I had just turned into a little school kid who could to wait to open the package and install the barrels. Opening the bag and removing the tube, you can see the tube was a blue, hard plastic pipe with 2 black end caps.

Removing the end caps the barrels were protected by 2 pieces of cotton wool which made a secure fit when sealed.

1st Impressions:

Upon removing the barrel from the packaging, I first noticed the colour of the barrel, I was (in my mind) expecting to see a stainless steel colour barrel, but as it turns out it’s just a lighter brass colour. It’s a lot shinier. The outer of the barrel is thicker in the middle than a precision Tokyo Marui barrel. At the two ends the barrel reduces in diameter to the same size as the TM barrel. This will help reduce vibrations as it is thicker and hence denser. Looking down the TM barrel its not that polished, compare it to the EdGI barrel and you can virtually see your face in it, it’s that polished.

TM:

EdGI:

Both pictures taken with a Nokia N95 8GB phone, taken in the same lighting conditions and virtually same position. (as you can see in the pictures the barrels are next to each other).

Fitment:

Strip down of the VSR is easy; this following guide will show you how to do it.

These are the 3 tools you will need, Allen key, Large Phillips head and small Phillips head screwdriver.

1st, start by making sure you have a clear hard surface to strip the rifle down on.  Lay the rifle out

Remove these 2 screws

Once the screws have been removed, split the stock from the working gear of the rifle.

Remove the scope if one is fitted, unfortunately due to my gas system I can’t remove the scope fully.

Remove the little screw that holds the outer barrel in place in the receiver.

Next, remove the top front screw out of the scope rail.

Now the outer barrel can be unscrewed from the receiver, put the receiver with the stock out of the way.

Now you can start to access the hop and inner barrel assembly. Start by removing the 2 screws that hold the hop block to the hop.

Remove the hop block and put it to one side also.

The hop adjuster arm needs to be removed now so the hop unit will slide out of the outer barrel.

Carefully slide the inner barrel and hop assembly out of the outer barrel.

Remove the 2 screws holding the 2 halves of the hop unit together.

Remove the lower part of the hop unit, careful to make sure the bb feed guide don’t ping out.

Now the 2 screws from the hop adjuster can be removed.

This now allows the barrel and hop rubber to be removed from the hop unit.

Remove the hop rubber from the barrel.

Remove the old barrel, get the new barrel and repeat the strip down procedure in reverse to re-assemble. Just remember to cock the piston before screwing the outer barrel to the receiver. This will stop any damage to the hop rubber occurring.

Remember to clean the inner barrel before shooting, just to make sure any manufacturing residue or dirt from installation is removed.

Comparison:

 

Top barrel is the EdGI one, bottom is TM Precision barrel. As you can see the EdGI barrel is 5mm longer.

The weights of the 2 barrels are:

TM: 103.1g

EdGI:  151.0g

EdGI’s barrel has a slightly larger outer diameter than the TM barrel around the middle of the barrel, the OD of both barrels is:

TM: 8.57mm

EdGI: 9.67mm

Barrel Construction process:

EdGI’s barrels are constructed using cold hammering process; this process is the traditional way of making all barrels. Whether it is a live firing rifle or an Airsoft rifle. The process of making these barrels actually adds more strength to the barrel because in hammering the metal, the molecules are re-arranged and thus make it stronger. Usually high pressure rollers are used to make the barrels inner diameter, They squash the slightly larger barrel onto a inner tube (usually out of harder material such as steel in the case of Airsoft barrels) this inner tube/bar is usually at the correct inner diameter for the barrel or slightly less so the barrels then can be ground down precise to the correct inner diameter.

Test firing:

Groupings with my Tokyo Marui 6.04mm precision barrel was 5” at 25meters with 2 shots missing, 4 being within 5” and the other 4 being within 9” of the centre shot. Also would hit full torso Inc the head (due to the variation in shots so much) at 40m with 2 out of 10 missing.

With the EdGI barrel, groupings at 25m was 5 shots within 1”, 3 shots within 2” and 2 shots within 3” of the centre mass. At 40 meters the groupings were 5 shots 4” groupings, 5 shots 2” groupings with 1 shot wider at 4“. (Groupings are worked like so, find centre of the mass, then work out, if the round is 1½ inch from the centre shot then I class that as 3” groupings and so on, so 10” groupings works out as 5” from the centre shot)

I expect with a harder hop rubber the groupings and consistencies will get better still.

Accuracy improvements:

The accuracy improvements this barrel give is fantastic, my TM 6.04mm barrel was good but this is perfect, the barrel has tightened the groupings. Except for the dodgy fliers due to imperfect ammo or sudden gusts of wind, this barrel will enable a torso to be hit in excess of 50m. Only time will tell with skirmishing this rifle what the in game improvements are like.

Conclusion:

Fantastic barrel, improvements to accuracy warrant the purchase of this barrel, I have gone from 9/10 shots hitting a torso at 35/40m to hitting 10/10 shots, and further more 10/10 shots to the torso at 50+ meters. I will one day find the maximum range and accuracy I can achieve with this rifle. I would of given the value for money a 10/10 rating if it had not been for the Xoom payments extra charge.

Ratings:

Build Quality 10/10

Value for money 9/10

Improvement to accuracy 10/10

Usability 10/10
