Who can be recomended that provides this service

I have a stripped Colt A3 upper which I wish to use for an SBR build.

So I want to have M4 feed ramps cut, ground whatever into it…

Where would you take yours to have this done?

What would you expect to pay?

I have a dremel and I have the foolishness to try, but first… an attempt at sanity.

Suggestions appreciated.

Check out Adco, they could probably do it.

Sell the Colt upper and get something from BCM or elsewhere that has the correct feedramps.

^^^Listen to this man

You are far better off selling the Colt and buying what you need and probably coming out ahead, rather than spending the money on shipping, machining, etc…

People will pay good money for a Colt upper regardless of feed ramps… and plenty of places of very well priced complete uppers that would put you money ahead.

I guess it would be easier to sell the one and find another properly spec’d upper.

Yep.
