S&W M&P 15-22 changing zero...

[Chainsaw]

These neat rifles are becoming more and more popular at Appleseeds. I really have nothing but praise for them, I'd like one for myself.

I am, however, hearing quite a bit of reports of the zero changing when used with a sling. It doesn't seem to be an issue with the barrel bending as in old thin barrel M-16s, but rather an issue with the upper.

My question is...

Has anyone had any experience with this... and/or know of a fix?

Never heard of, or experienced that problem. Guess I mostly shoot it off the bench or using the bi-pod.

I like this guys solution though.

That would probably work just fine.

If leaned on hard enough the gun flexes because it is made of plastic. This is the only issue I have heard of. I have never had an issue with mine.

Nutinfancy (however it is spelled) has a vid showing the POI changing because he is pushing the gun down hard into a sand bag
