I own a 150cm Kanji and find it to be a really well made gun. It is a little long for my liking but the reason I have it is because the price I got it for. The barrel has internal ribs that run lenghtwise making it resist flex when loaded, the rail also features mini ridges that run lenghtwise and reduce the contact area between the rail and the shaft and its suppossed to have less friction. The coating on the aluminum barrel is excellent and resist hits and scrapes very well and compared to other coatings I've seen on barrels like anodizing or regular powdercoating this one seems to be a little thicker. The stock handle could be a little big for people with small hands but it's perfect for me. Also some people would like to have more of an angle on the grip, something that the makers tried to solve with a new handle grip but I do not have it so I cannot comment on it. Things that I don't like is that there is not much space inside the mech for thicker mono with the stock shaft (8mm), that megatex rubber that comes stock has a nice smooth stretch to it but it's not very durable, bungie is made with same rubber and didn't last long but I find most bungies to be the same way with the exception of Riffe's and Rob Allen's and now trying Mako'sto see how much they hold. Shaft is like any other spring steel shaft with tri-cut tip and notches. The price for this gun was around $595 and while very well made I feel it was too much for a railgun. Now that they have come way down in price, around 260-300 I feel that it's a good gun to consider purchasing. It shoots very accurately out of the box but like any railgun you can fine tune it to your liking. I considered cutting mine down to 130cm if I cannot find a shaft for it with a rest tab and shark fins so I can put the mono on the fin and out of the mech, or a thinner (7.5) shaft. Also Kanjis were made to up to170cm making them one of the longest railguns available. Pelaj's Nemesis are also made with the same features of the Kanjis but with different muzzle (closed) and Specters have different cammo color on the barrel and a lower price.
