I would like to know what weight recoil buffer I can use on a M4 upper that has the gas port drilled out to .093in. The reason the gas port was opened up to this size is because this rifle used to have the old counterpoise system. I am not using the counter weights or the original buffer because both are FUBAR. I would like this rifle to be dependable with this gas port size. So, if anybody can help with any suggestions, I would like to replace the recoil buffer with a heavy weight but do not know which one. By the way, the barrel length is 14.5in. with phantom flash hider. I know about the adjustable gas tubes by MGI, but would rather not go in that direction unless necessary. hy.gif |
| well a 9mm Buffer is 5.7 ounces..I dont know how much resistance the old system gave but theres always the enedine buffer,that will give even better cusion for something thats gonn run a bit harder than normal.I dont know who does it but I have heard of inserts that can make the port hole a normal size again.I think for 14.5 its .060 or 063 not sure. |
No amount of heavy buffer is likely going to make up for this large of a port. Cut the barrel down to 10" and it should run fine. If you want to keep it at 14.5", you should really fix the gas port rather than patching all the problems that it creates. I charge $25 to install a bushing in the barrel to reduce the port size back down to spec. |
He works rather quickly. Shouldn't take too long, I would imagine... TS |
