wobble on the lower receiver

[M4rk]

been fondling the gun for a while, and all of a sudden, i noticed a little wobble(play) from the handle up to the lower receiver. i opened the gun up.. tried moving the inside-lower mechanism of the gun, and it does have a little play. if u guys get wut im sayin... is that normal?

and while i was cleaning it last week. i also noticed the 2 allen screws that holds that inside-lower mechanism piece together was loose. so i tighten it up.

You mean the grip is loose, or the lower reciever isnt locked in against the upper reciever?

If its the grip, there is probably a screw inside the grip that will tighten that up. Im not sure because I dont have a umarex AR, but look at the bottom of the grip. Its either hollow with a screw/bolt up in there, or there is a cover that you can remove to access the screw/bolt.

If its the fit of the lower to the upper....not much you can do there. A gunsmith can probably peen the pin lugs a bit, or maybe shim it????

The grip bolts into the trigger group, and if that is loose, tightening the compensator after cleaning won't tighten up the lower to the upper. Check the grip screw first, it is as bdavison said, a bolt up inside the grip.

any other places that i should look for, wer it might get loosened up from shooting?

Two set screws on the bottom of the quad rail, just in front of the mag well, keep them tight. And I put a registration mark (dimple with a center punch) on the compensator so I can tighten it consistently every time for accuracy.
