Masamune Extreme Precision 6.01mm AEG Inner Barrel for MK96 (510mm)[I06G00 / SF27][06342 / GImasa510mm]
New to airsoft? Here are some safety tips for airsoft guns that we recommend following.
The Airsoft GI Masamune 6.01mm Precision Barrel is the tightest bore barrel available and the only choice for players looking for the best possible accuracy and range.
The bore of this barrel is so tight around the BB that even the smallest obstruction in the barrel will cause a jam when fired. This barrel is recommended ONLY for advanced/experienced players that take the responsibility to clean their barrels regularly in order to avoid jams.
- Manufacturer: Airsoft GI
- Color: Silver
- Size: 510mm
- Material: Brass, Chrome Coated
- Package Includes: One (1) Precision Inner Barrel
First I recieved the item with no lid so the barrek was hanging out a little. Then, I got a better look of it and noticed that that the tip of the barrel was bent. So it made it not shoot straight. It came with no instuctions and I was really displeased with support I got. I hope this doesn't happen again. By the way it's a pain in the $%# to put the barrel spacers back in. You might want to buy the Polar Spacers made for this gun, if you chose to buy this piece of crap. I reccomend buy the new G700 instead, beacause the parts are already built in and you save money in the whole process.
A bit to long
Mine came bent with no lid
Need to buy barrel spacers or make new ones
When I bought this 6.01 inner barrel I was excited to finally see that my UTG MK96 would have its last upgrade. Once I started installing the inner barrel I came across some problems with the stock hop-up. I noticed that the divot for the bucking in the hop-up was upside-down in comparison to the hole that allows the bucking to be adjusted to reach the BB. After deciding to just put the bucking in upside-down, I found that the other grooves in the barrel aren't in the right spot for the hop-up. The metal rings that are in the stock hop-up that clip onto the stock barrel to keep the hop-up from sliding around are in completely wrong spots. After toying around with how I'm going to get the hop-up in aside from the bucking, I just decided to stick the hop-up in without the metal ring. Now my hop-up isn't even secured properly onto the barrel. To keep the barrel from bending, and sliding I had created my own home-made spacers. By wrapping Permacel (electrical) tape multiple times around a section of the barrel 6 times helped both quite the barrel from firing, but also helps prevent the inner barrel from shifting out of the hop-up somewhat.
Now that I have the hop up on the inner barrel, and the spacers made, I found that the inner barrel is also too long! Now that the inner barrel is a tad bit long, I couldn't fit the metal screw cap on the tip of the barrel because the hole is too small, so I had to shave out the hole. Now the inner barrel sticks out a couple centimeters (cm).
I was going to resolve this buy purchasing the Guarder Maruzen Type 96 Threaded Adaptor. I was excited to buy this so I could also put on a silencer and add that stealthy look to my gun, but as I asked when they would get the threaded adapter in stock, the General Store Manager (Frank Chu) said it would be 2-3 weeks. It has now been 2 months past, and there hasn't been any change. I am still wondering if it will ever be in stock.
Performance wise, I think that the 6.01 really helps the shooting performance of your gun! I was able to reach further distances with my new upgrade, and It would shoot straighter for about 30 feet longer. There still is a little bit of inaccuracy with the BB curving away from the target with .25g BB's. I think that I may want .30g BB's. Otherwise, I think that the 6.01 dramatically increases the performance of this gun!
I don't use it with the UTG upgrade kit! I have found that when I include the upgrade kit, the BB fly's way more unpredictable, and curves way to much. Therefor it is somewhat useless having.
Shoots further without curving
◘The stock hop-up doesn't fit well
The bucking has to be installed upside-down
The stock hop-up isn't secured right do to the incorrect divots
◘The barrel is a little long
Makes you renovate the screw cap
This barrel is amazing, but required some modification to the orange plastic front barrel tip to use in my UTG MK96. Turned out that my stock barrel was put in upside down from the factory making my hopup useless...Great!
I suggest when installing this kit do these three things:
Take out all of the rubber barrel spacers, there should be 4. This was by far the most time consuming and pain in the ass process, took me about 25 minutes to get them all out. Inginuity is key here, I used about 25 drinking straws to push them all out, just put them into the orange tip until they start to stack and push out.
Use a drill with a drill bit the size of the outside diameter of new barrel as you need to increase the hole in the orange tip of the outer barrel to the outside diameter of the inner barrel (cause this barrel will stick out past the tip only by about 3-4mm, but this barrel is longer then stock so it requires modification.
Lastly, evenly space the rubber spacers on the new barrel once you've installed the hopup unit, and place electrical tape to a little under the diameter of the spacer on either side of the spacer to get it to hold in place. Make sure you leave about 1 inch free at the end of the barrel (orange tip side) because it will be sliding into your newly cut hole and thats just the size you will need.
Despite other comments and reviews, (coming from a tech)This barrel DOES have a perfect fit into the UTG MK96 stock hopup unit and because of that it will work with upgraded hopup units available
Flawless fit into stock hopup unit
Barrel hopup cutouts perfectly match stock barrels making the fit perfect
6.01 inner diameter, how can you beat that?!
CHEAP!!! Best upgrade for the price
The ONLY con to this barrel is having to modify the orange tip, but on that note doing so made the barrel more sturdy as its not being held by the orange tip tightly.
Will this inner barrel work in a bravo mk98 spring sniper rifle?
Want to upgrade the barrel of my bravo mk98 snoring sniper rifle from a 6.05 to a 6.01 and wasn’t sure if this barrel is compatible. If not, could you steer me in the right direction of what would be.

(I have this same question)
The barrel should be compatible. It may not match the stock barrel length for that airsoft gun.

Would this barrel fit a kwa lm4 with a mad bull barrel extension.

(I have this same question)
The inner barrel will not work. The inner barrel for the LM4 is designed differently. The barrel extension will work tho.
