TKOverKill

The gun is fully tuned internally (shimming and a few other things) and has a new airseal. The compression is very good. Also the hopup unit has been modified significantly. This gun can constantly hit the 40 meter target at SEALS. FPS is 92m/s

Custom parts:
Angel spring and piston + piston head
TM hopup bucking
H-style nub
3 rails





This gun does not have many reviews because of its relative rarity. I found just one good review:

The summary is that this gun is built like a tank. The upper receiver is aluminum, and relatively scratch resistant for an A&K gun. The lower receiver is some sort of a fiber material. It is not ABS. You can test this by compressing the magwell and seeing how far you can push it. On a Marui M4 you can compress quite a bit. On the Masada there is almost no compression.

I have gone through the gun with a razor (literally) to remove any molding imperfections. Visually, the gun is stunning.

Performance:
92 m/s
40-35 meter range
18-20 rounds per second on a 9.6V (gun can take up to a 11V lipo)

Gun is sold alone.
Price is 19,000 yen
All M4 mags will fit for it.
9.6V mini battery is an extra 2,300 yen.
I have hi-cap PMAGs (1,000 yen) and standard Marui Hi-Caps (700 yen)
EOtech 551 replica is 2,700 yen.

As always, my prices are open to negotiation. Swaps and splits are also accepted.

Is this the same MASADA that is referenced in this post?

You mentioned accuracy issues and were exploring the idea of changing the barrel. Did you ever do that? Is the accuracy better with the power stabilisation? My buddy is looking for something like this, so any other info would be appreciated.

Thanks

You're right, this gun needs more explanation.

The barrel is 6.01. I had the guy at Echigoya measure it with a caliper, he was so surprised that he continually remeasured it but got the same result each time. Even if you buy a PDI, it will not be 6.01 exactly. So really, I can't imagine a better barrel than the stock one.

The hopup is another story. Again the guy at Echigoya was a big help here. He replaced the hard bucking I was using with a soft one and then put a spacer in the hopup chamber. This made it work.

Stablizing the FPS and tigthening compression also made a huge difference.

This gun is accurate to 35 meters no problem. At 40 meters, wind and other factors do become problems. But with no wind and sights adjusted, I was able to nail the 40 meter SEALS target about 7 out of 10 times.

Internally and externally the gun is practically new. Better than new actually since I went over it with a razor.
