I have a couple of uppers that do not have M4 feed ramps cut into them. Is there anyone in the DFW area that cuts these ramps? If so, let me know and let me know and if you know more or less what they charge that would be great.
Thanks.
Unnecessary and detrimental to longetivity.
Either replace the non-ramped upper with a ramped upper or just leave it alone.
If it isn’t giving you issues now there is no reason at all to mess with it.
You need to get uppers that already have these cut in and anodized, and sell the old ones off.
he is right better to get factory uppers with them already cut .
sell them off and just replace with a good upper .
by the time someone cuts them and refinishes then you could be out more money plus if their not cut to spec it could cause problems down the road. just my 2 cents:D
The Colt feed ramp is cut to a very specific angle and profile.
Most gunsmith jobs do not meet these specifications and most gunsmiths don’t know what angle and profile to cut them to and don’t even know this specification exists.
Assuming the rifle is working now, why do this?
Thanks for all the comments. These are stripped upper receivers so the gun is not running at all yet.
