Can’t say I’ve ever caught my front sight on things while hunting. :)

That's made to loop the sling though. We assume you want to be able to detach it easier, faster. So what hardware are you working with? What's at the end of your sling?

If it has an M1 receiver, shaped like... you know... an M1 then no the M2 stock won't work. (or it will but will be an ugly mismatch, your receiver sticking out past the stock.)

What is it lacking already that you need to remedy? lol I can't speak to a re-released version of the M1, but the differences between the original M1 and M2 were, other than re-contouring of the receiver and the new furniture that went along with it, mostly changes to make manufacturing faster/easier/cheaper. They still interchange between the M1/M2.

I'm sure if you heat it hot enough and whack it with something it will come off. (and look pretty bad afterwards) But why I'm wondering? With the height of the receiver, plus rail, plus mount/scope height, it can't be in the way??

Move random by the minute.

My eye/brain sees the classic ribbed shotgun forend like a pump gun and expects to see a smooth grip.

While that was also true, what I thought I typed was "I don't hate the wood." I didn't even notice that in the photo. I get what they were going for, the rugged industrial look, but perhaps they didn't think it out far enough putting it in front of a roll off dumpster. "At least you won't have far to walk to throw this POS away!"

You're probably describing the problem. Barrels "whip" when fired. Since the M4 barrel is supported at the receiver, and by the muzzle, the middle likely is doing all the moving. Unforgiving metal materials, tighter fit all together, throw in some staking tolerance issues and it just doesn't have the ability to move like it needs to. The welds/braze/solder or whatever means they're using doesn't have the shear strength for the added force. Probably a tolerances issue, because for every one person it breaks of for, there's probably fifty it doesn't.

Make a nice movie prop maybe. lol Honestly I don't have the wood, but checkering on the wrist look out of place with the rest of it, looks like it belongs on a mid priced 1970's bolt rifle.
