Like a machine... - JP Enterprises Gen 2 Silent Captured Buffer Spring System

Ever charge your AR/M4 and hear that grating, sandy sound? No matter how much lube you put into it, no matter how many cleaning cloths you jam in and twist out, no matter how hard you try to clean it, it always has that sound. I'm weird and take pride in a clean weapon (on the inside), because that usually means it cycles and pews longer than everyone else.
Like self-contained drop-in triggers, this is a self-contained buffer system. You pull out your spring and buffer, throw this in there and it's ready to go. You can even take the time to remove the retaining pin if you're bored enough. It's about as easy an installation as you can possibly get.
Now as far as functionality, how can I put this... It's buttery smooth. If you've ever seen a cutaway of a car engine, watching the piston move in and out of such a tight space because it was made to be there, sexual stuff aside, this is about as close as you can get. You might be thinking it's a bit unnecessary or a solution in search of a problem. After all, what do you need besides a buffer and a spring? You'll think very differently after trying this. Put simply, it just makes cycling better. It's not perfectly silent, but it's quiet, very quiet, because the spring doesn't press up or move against the inside of the buffer tube. And the weights are held in line. While traditional buffer systems kind of flex and bend as they go through cycling, this moves in a straight line. It smooths out cycling and makes it very quiet. Granted you probably can't hear it when there's a loud bang, but if you're running a suppressor, it makes it even quieter.
In terms of functionality, it doesn't necessarily make a huge leap towards an improvement. Is a regular buffer and spring enough? Sure. But if you have a decked-out AR, I would strongly consider swapping this in, especially if you're running a suppressor. I just like the way it makes my weapon cycle. And it gets rid of that sandy sound.
