I found welding upper to lower fixed this issue permanently.

After weeks, i have found the mage who has cracked the code. Thank you. My PSA is solid now 💯🤜🤛🔥

Buying matching upper and lower won’t guarantee no wobble.

I put an O ring around my front pivot take down pin

That trick just worked great on my Troy AR’s wiggle! Thank you!

Just finished my 1st build and noticed this problem. Saw another video that says use O rings. Dont have any of those but i have hundreds of ear plugs. Thanks for the info!

I just got some Orings today & I put them on the the front & back part of the upper & not it does not wiggle, it feels 100% solid it’s perfect

i hate the wobble! that's cause i even have a matching psa lower and upper haha, great tip!

Saw someone else put several squirts of hot glue in rear… then close up for perfect fit… make sure parts are lubed b4 using glue, , ,

My grey ghost lower has a tension screw in that same location just for this purpose. I had no clue what the screw did until a few days ago. Funny I’m now seeing a video about this.

That's a neat trick, I had the issue, I placed a small rubber o-ring on the front take down pin. That gave me a perfect fit feel.

I used a piece of a sanding block worked perfect, thank you

[kurojakigames]

This was actually very helpful because my lower and upper are matching brand, but I still had a pretty bad wobble. It was still functioning just fine, it wasn't an unusable amount of wobble, but it was enough to bug me, so thank you a lot for this trick!!!0

Best way go get #5 taper pins and a # 5 reamer, clamp upper and lower then ream. Any movement in your gun will affect accuracy, it is said the more you make your ar like a bolt action the more accurate it will be.

My colt sp1 has a looot of wiggle. But it adds class.

The reliability should still be 100% right? It's only aesthetically wiggly. It won't break on me will it

[B.Harrigan]

I try amd keep shit that can cause a malfunction out of my recievers, not add it in myself.

Fixes that push from beneath the lug do not eliminate the pivot point wobble and movement continues. The AR15AccuShim eliminates side to side movement, fix it right.

[andrewrobb]

foam ear plug under the takedown pin will do it

[arnolddamnit]

What to do if my front pivot pin has play

[panther]

A few tiny black rubber bands did the trick on front takedown pin
