Quick AR Question

[porscheboy]

Im in the process of building an AR 16" upper, just one problem, Im not quite sure what M4 feedramps are? I understand that if you have an M4 upper receiver, you need to have a barrel with feedramps as well. Also does this barrel have M4 feedramps....? The website does not specify.

no idea about that particular bbl, but my guess is no

Without seeing the chamber area its immpossible to tell for sure.

However, I suspect that if it were cut for M-4 feedramps it would say so

yea my guess would be no also....call midway and ask is prob the best thing 2 do

A call to Model 1 Sales might get faster results than Midway since Model 1 Sales supplies the barrel to Midway.

M4 feedramps are basically extended feedramps that go farther down into the reciever extension as well as the barrel. theyre a little wider than standard feedramps as well.

basically, if your reciever extension has M4 feedramps, and your barrel does too, your GTG.

a M4 extension with a standard barrel however, is a no go.

hope this helps,
Kenny
