AR15 Buffer Assembly...Please help.

[DML2007]

I just received a new Buffer (the actaul device that looks like a metal plug), and was inspecting it. If you were to shake it softly like a rattle, is it supposed to have some loose parts inside of it? It is a standard length buffer assembly. My cabine buffer does the same thing. Is this normal? What am I hearing? I dont want my AR to sound like a beer can with rocks init...you know?!

Thank you. DML

Yes, the 'rattle' is the actual part that buffers the recoil.

yeah, perfectly normal

The best advice to you is to lube up your buffer and spring with something nice and goopy. Personally, I like Militec. Otherwise, it'll sound like the world's largest, cheapest screen door every time it recoils, right next to your ear, no less.

Perfectly normal, and I reccomend not putting anything goopy on the spring.

The "sproing" is a good noise. It makes that noise when the bolt carrier goes back into battery. No sproing means the mag is empty, or you have a more serious problem.

Or you can go with a mechanical or hydraulic buffer.
