M&P 15 movement between upper and lower

I have seen expensive guns with movement between the receiver and upper. Accuwedge is the way to go.

It will stop the wiggle but the little bit of wiggle doesn't affect anything negatively. It's a waste of time and money trying to get rid of it.


I think you have the best sig line I've read so far :)
 
The concern I have with the Accuwedge (other than the distintegration mentioned earlier) is that it places added (and undesigned-for) stress on the upper receiver lug, receiver takedown pin and takedown pin holes in the lower receiver possibly causing premature wear.

I thought they came from factory on Colt Canada rifles? I know a site sponsor sells them as being OE from CC.
 
Thank you so much for all of your replies. This is why I Love CGN.
BTW, I took my boys to the range last night and blew thru a couple hundred rounds. What a great way to spend time together. Gearing up the wife to come next. It was their 1st time shooting the AR, and they can't miss with this thing. I don't know much about ARs yet, but it seems like the perfect gun for us at least. Comforting to know the slight movement is normal

My brand new Colt Canada Lower has the rubber insert. I did not know it's called an accuwedge.

I was having trouble getting the take down pin in at the rear, so I reached out to a friend that is a Colt Canada trained armorer and he assured me that it was normal and should stay there.

Exactly what he said. I wouldn't even bother with the wedge. It just makes disassembly harder as you may need a punch.

You almost definitely need a punch with an AccuWedge (or a dummy round).

They're fairly solid so I doubt they'll disintegrate easily (mine still looks brand new). I wouldn't say it necessarily adds more stress or leads to wear because it is ensuring a tighter fit - and there is little if any play between the upper and lower when in-use. Some of the pins on my ACR are even tighter (although that's not necessarily a good comparison). I find that an upgraded set of takedown pins is best to have with the AccuWedge (like the BattleArms which have a dimple for a shell tip).

It's also completely fine to run without.

You can always shave the bottom of the accuwedge down until it's eating up the play but not putting much tension on the pin.
 
Normal, doesn't affect accuracy as soon as you get over it and stop getting distracted by it.
If you're OCD or ADHD it might distract you, in that case either get the wedge or install a rail mounted fidget spinner.

Thanks. What is this "rail mounted fidget spinner" you speak of, and where can I buy one? Do they come in FDE?
