Product Information:
I purchased this for a well mb06 sr-2 sniper rifle I got for really cheap. Stock it shot 1.5 joules, (320 fps with .32bbs) or field limits for an AEG. With this simple kit and 5 minutes of work it took my sniper rifle to 2.55 joules (414 fps with .32 bbs.) I believe field limits in my area are usually 2.88 jouls for bolt action sniper. So I'm not over limits but competitive)perfect! Note: I used an acetech 5000 chronograph and elite force .32s for my tests.

Easy to use and install, for myself all I needed was an allen set, a Philips head screwdriver, and some silicone oil. Not exceeding field limits.

I feel that it will wear out the gun faster, puts more strain in the trigger box etc... But without it my gun would be garbage.
