Does anyone know where to buy a 3/6 M-4 elevation adjustment wheel, for the carrying handle? Mine is the standard 3/8 M-16 A2 adjustment. I've looked and can't seem to locate one. Help me out here!!!

The reason M4s have a 3/6 adjustment instead of the standard 3/8 is due to the removable carry handle. A2s will have the full adjustment while the detachables won't. This has nothing to do w/ the capability of the rifle itself, but because there's not enough "room" in the detachable carry handle to accomodate the longer adjustment cylinder. The detachable carry handle must be "beefed up" on the bottom for strength, so that adds metal. In turn, there's not enough room. I hope this helps.

Thanks, but where do I get the elevation wheel? DG

Do you have a fixed or detachable carry handle?

I have a detachable handle, but I need the right wheel adjustment with the 3/6. DG

I think Brownells sells the parts. Are you sure it's an 8/3? Does it elevate all the way to 8? Do you know who made the handle?

Whoa Partner, the wheels are not interchangeable with the opposite elevation elements. The carbine's whole unit has a much finer "acme" thread than the A2. If you really got to put an 8/3 unit on a carbine, you got to mill a hole through the upper receiver so the botom of the elevation element has a place to go. Not as big a deal as some think, as every A2 ever made has this hole.

I might also add I like the carbine (finer thread) rear sight in my now "only for civilian use A2." If gives me finer adjustments at the under 500 ranges I shoot to now days.
