"This product is tenfold worth it's price.

I am an experienced airsofter, being that I have repaired and upgraded just about every common AEG and Bolt-Action Rifle, and I can tell you that the SCS is an amazing innovation. The concave shape allows to the hop-up rubber to be conformed in the most even way to the bb, allowing the most balanced contact with the bb, thus resulting in an consistent hop-up that results in tighter grouping and increased range.

The SCS can be used with any AEG, and is also able to be used in a Bolt-Action Sniper with some modification, which can be found on your favorite airsoft Form, or Shredders own website.

I have bought 4 of these, 3 of them being a direct drop-in to an AEG, and all have shown impressive results. The other one was installed in my Bar-10 and has wielded great groupings!

"This is definitely a smart upgrade to a high-end AEG.
The machining, equality, and overall build is fantastic. It is slightly larger than most hop-up spacer corridors, meaning this is somewhat frustrating to install since the spacer is a little bigger than the slot it need's to fill into. But once you get it in, its not going to slip or lose position, so get past the installation and you're good to go.
If your hop-up bucking is rather solid and tough, the shaping won't take affect. If the bucking is flexible, it should work fine like it did in my gun and you should get improvements in accuracy.

better accuracy
made well

pain to install
only works with flexible buckings
