Does this barrel have the M4 feedramp cuts and, if so, will they align properly with a Colt M4 upper?

Negative The upper lacks m4 feed ramp cuts. At least mine lacks them.

I was afraid somebody would say that. [:(]

You are just asking about the barrel? I believe the Colt upper is what has the "extended feed ramps" machined in it, not the barrel, I think. Do a search on them because I have seen some photos of the extended ramps here.

The M4 feed ramps are a proprietary, patented feature of the M4, a commercial design owned by Colt's. You can easily deepen the barrel ramps to match the Colt's receiver receiver ramps, but it's not necessary. Been shooting a Bushmaster M4 barrel in a Colt's M4 receiver for close to 3 years with no stoppages. -- Chuck

Bradd, Don’t despair. Send your barrel and upper to Kurt and he’ll fix it up right for you!
