Were I you, I'd just spend the money on the part I linked to.

I guess I didn't realize there was a question about that.

I thought you were just making sure I knew it was from barrel pressure or just poor trigger control. Which would be the first thing I would ask someone who I hadn't seen shoot.

Nah, your description sounded pretty cut'n'dry so just go go spend $300 on a Geissele trigger

That is also what LL recommended.

I just hate to spend another $100-200 to get a plastic gun to shoot.

None.

I have a 2nd one, that I am going to check tonight to see if the barrel will wiggle on it. I didn't have it with me yesterday as I was trying to find out why I was missing low and having to hold over so much with the M&P 22 vs my old Marlin when I was shooting at varmits over the last couple of months. I thought maybe I had knocked the scope out. That is how I discovered this problem.

I will check tonight, if it doesn't move and this one does, I will let S&W know and see if they can help me out or I might just buy a barrel nut wrench.

I assume a standard AR barrel nut wrench doesn't work?

You don't need to do what I did, just use the mag as a mono-pod and you won't have any more issues!

There is little on that forum that you cannot find here (FYI).

Problem is magazine mono-pod can often open up my groups greater than minute of squirrel/turtle.

Plus, I can't alway shoot from prone so I have to brace on something and it seems to wiggle too much then too.

I know I was greatly irritated when I missed a squirrel off my back porch and I distinctly heard the "slap" of hitting the stump he was sitting on and it was an easy shot. A shot I have made multiple times with my Marlin 881 and my Marlin 39a.

I also noticed that when I was shooting turtles in the lake that from sitting I was hitting the logs under them unless I held over to the thick part of the duplex reticle, but then when I moved to another location shooting at targets farther away from a good solid prone with the same hold over, I was hitting way OVER them and I had to hold directly on them.

I got out my old Marlin 881 with its old $8 Simmons 4x and I seldomly missed and it has a very sloppy trigger and it doesn't normally shoot as tight as the M&P from bags.

Thanks for the help guys. I may just break down and put a cheap slick FF rail on it.

I was having POI shift issues with mine through various shooting positions while working with a VTAC barricade. I pulled the front cap off to realize the barrel was very loose in the upper receiver (barrel nut has backed off). I'm going to tighten the barrel nut and remove the factory end cap to see where that takes me.

I am not sure how using the mag as a mono-pod reduces accuracy (unless you are putting pressure on the rail at the same time).
