Review: The marker setup above is my new setup... Ive donated my A-5 to my brother... the review is still valid, don't worry :D

This thing is alright. The best statement I've read yet is "you don't get much for your money" -- which is true, all you get is an almost-indestructible spare. The best thing about this assembly is that you get higher FPS out of it (I don't know how -- maybe a larger orfice in the front of the powertube? Haven't checked), which probably leads to increased gas efficiency. Other than that, you get a few small lows, and one BIG problem.

The powertube/front bolt, while it is more difficult to slide in (because it's METAL and metal doesn't BEND/SHRINK like plastic does) should NOT pose a problem, because you SHOULD have polished your internals! But even when you have, it is a bit tougher than the plastic one. If it's that bad, take the gun halves apart and do it that way... Just make sure you line up the tombstone slot (which is easy enough if you unscrew the velocity screw and set it in before putting the other half on).

I have noticed no extra noise with this setup, nor have I noticed a reduction in BPS ability (though I don't have an RT/E-frame so I wouldn't fully know).

I've found that while the Velocity adjustment screw is "better" in that it's easier to turn, it's also looser, and anything further out than two turns from all-the-way-in gives you 300+ fps on CO2. The extreme downside to the looseness is that just from the recoil shock the screw can (and i have taken the brunt of it) unscrew itself, raising velocity over the course of the game.
After 2 hours of recball, my brother, who was using the A-5 at the time (and who chronoed in at 240bps at the game start) hit me in the bare arm once and clothed back twice, drawing blood on my arm. I had him chrono in again and he was shooting an unbelievable 365 fps. This is NOT safe at all, and it hurt like nothing I had ever felt before. If I could post pictures of my arm wound, I would. It looks like a sunburst tattoo. Anyway, MAKE SURE you put teflon tape on the velocity screw before use, and just to be safe the first couple of games, chrono in a couple of hours post-start to be sure you won't be wounding anyone.

Other than that, It's alright. People that complain about "reduced bps" should slap a heavier spring in. Works great. Like you can actually shoot 15 constant bps on a mechanical trigger anyway... Has anyone tried modding the e-frame to shoot faster than 15bps and find out how fast the Cyclone can REALLY go??? :D
Conclusion: It's a good "replacement" (read: NOT upgrade) to an already quite acceptable bolt/powertube. While you may notice increased efficiency and FPS, be sure to wrap the new V. Screw in teflon tape to avoid shooting 350fps+ paint-bullets at people.
5 out of 10
