Did I screw the pooch?

[BroodXI]

Bought some parts from a crowdfund a while back. Got a few raw uppers. finally got around to building with them this month and noticed no m4 feed ramps. I know i don't need the ramps, but i wanted them. I of course didn't have the correct tools on hand to do the job. I chucked up a dremel grinding stone into the only tool i could find. Happened to be a hammer drill. I guess when you can see this going.... Think it's salvageable?

If it's a loss, i'll call it a lesson learned.

Does it still chamber rounds consistently?

well i haven't gotten that far yet. I just slapped another upper on the build. I also picked up and 80% that miraculously got shipped, but it didn't take ano very well. figured i would use the two in a 300 blk build. Ill try chambering some rounds tomorrow. Thanks

No knock but seriously.....proper tools for the job.
I only stress this as I and many of my friends have spent insane money on tooling over the years. It makes life and projects so much easier.

See if it will chamber rounds before you pitch it.

I would run it. There's not alot of stress in that area, the round is higher up from the receiver so it wouldn't be impeded by those marks. I'd buy the upper from you if you want to sell it pm me...

I have to admit, I have a couple of guns that I can never sell. Not all one type either. I had good intentions too. But at least they still function reliably.

I guess thats what you need to find out.

It might be salvageable...here's a pic of what it should look like

It all depends - Is your dog pregnant?













Hey-
If it runs good and nobody but you is going to see it, then work it like an ugly girlfriend in your remote cabin.

No worries man, just fill 'er with JB weld and try them cuts again.

I very much doubt rounds from the left side of the mag will chamber reliably. I had an Adams Arms barrel with the feed ramps out of spec (much less dramatically than your situation) and it was nothing but problems.

This was enough to catch the nose of the rounds from the right side of the mag...

You won't know until you try it. By some miracle it might run and if it doesn't you don't have to worry about messing it up by tweeking it until it does. If you have to use your drill again I recommend that you take it out of the "Hammer" function.

That was a headache.

That was a headache.

Chezuki normally is a headache.

Yep lesson learned. Shouldn't have held the flashlight in my mouth while i was working on it. Might tinker with some alumiweld. almost didn't notice the comment about jbweld was in purple.

Is this a joke? Every time I hear "dremmel" in the gunsmithing forum, I cringe a good bit. There's very few things (like chopping a FSB down or sanding off Glock finger grooves) that a dremmel is appropriate for.

what do you suggest other then a dremel? a file? i've done another with a dremel and finished up with a jewler's file with no issues. I'm being serious here, please tell me how it should be done. thanks

 

[maxmayhem]

pitch it...spend 40 bucks and get a new one...this is insane

 

[seedubs1]

How should it be done? It shouldn't. If you want M4 feed ramps, buy an upper with M4 feed ramps. Trying to put in M4 feed ramps with a dremel is.....well, it's most definitely not the right way to go about it even if you're dead set on machining in feed ramps.

If you really wanted to do it right, you would need some sort of a jig to file it appropriately or a mill. But the real answer is that it's not a standard gunsmithing operation because you can just buy an upper with M4 feed ramps if you really want it. A dremel most certainly is not the way to go about it.....as you can see from your handy work.

This would be the correct answer.

In the right hands a Dremel can do works of art.
In the wrong hands it can be a force to cause much sadness.

I have a couple of Dremels. the cable wand, all the bits and pieces available for them.
I have achieved much with them and have destroyed a few things experimenting in the same fashion.

As with any tool.......take your time. Clamp down your work. Brace your self up. Run the tool do not let the tool run you.

Oh......and get some proper lighting over your bench.
