"The reason I purchased this was because of stupidity on my part. I had installed a new double O ring aluminum piston head in my stock A&K SR-25k. After rebuilding the gun and doing some tests in the back yard the gun stopped. After opening the gearbox I had found that I didn't completely tighten the piston head bolt and it had come off during the tests. This had caused the piston head to move around and scratch up the inside of the cylinder and eventually seize. The gouge in the cylinder was too deep to buff out.

When I tried installing this it turned out that the cylinder was about 1.4mm, according to a micrometer longer than the original A&K cylinder and had to be sanded down. I originally started this process by using a 150 grit sheet of sand paper and taping the edges to the glass on the dining room table. Then as I got progressively closer to the desired length I switched over to a finer grit paper until eventually I finished with 800.

The inside surface of the Energy cylinder left a lot to be desired. After reducing the length I went to work on polishing the inside. Using Mother's Mag and Aluminum polish that I got from Autozone I went to town on it with a pencil attachment for my Dremell tool. After polishing the cylinder 3 times it was like a mirror, though distorted because it isn't flat.

After all the work I put into this cylinder to get it just right it works really well! But then I did put in a ton of work... As an out of the box replacement part I would not buy it again.

"I bought this for the SR25 gearbox I'm building from the ground up and it seems to be working very nicely. I have it installed in a Matrix Ver. 2.5 gearbox and despite the ribbing on the outside it fits well. It has great compression with the cylinder/piston head I'm running. So good in fact that I can't even compress the piston half-way.

The only negative thing I have to say about this cylinder is it will NOT fit in an A&K SR25 gearbox shell unless you dremal the cylinder window, which I didn't even want to waste time on.

Does what it's suppose to
Chrome color
Ribbed(can be a con also)

A bit pricey
Again it's ribbed
will not fit in an A&K SR25 gearbox shell
