Hello,
A friend of mine has DPMS AP4 LR308, I currently have 200 rounds through it. It seems the buffer spring makes a lot of noise during it's function. I have a LR308B and doesn't make a fraction of the noise. It has well over a thousand rounds through it. They both have as issued buffers and springs. Is there anything that can be done or some kind of additive that can be used to possibly quiet it down. Would the round count make a difference? Any information would be appreciated. Thanks |

Some readers have suggested a lube or grease for the spring. While I agree that takes care of the noise, a greased spring requires one other bit of care. It is possible that grease could clog the hole at the rear of the buffer tube, with the result that you add a bit of resistance to the buffer moving to the rear. That slowdown COULD be enough to impact functioning. I have had it happen only once and that particular AR had thousands of rounds through it before cycling became a bit sluggish. Cleaning out the tube and then reapplying grease solved the problem, but it's something I watch for on heavily used ARs. Again, rare, but possible.
BTW, the JP captive spring system solves ALL problems with noise and functions like a champ. |

A JP SCS is the best solution. 
In my 10.5 w yhm phantom (ss thread on) it has made more difference than the silencer. (With proper hearing protection of course! And shooting in an open area) it feels really neat, almost like a piston guns recoil. Very good product this |
