Thread: Utas .223

The .22lr drop in kit will suck for accuracy due to the 1 in 7 twist.
Dedicated .22lr ARs have a twist of 1 in 16.

If you want to change the trigger, just be aware the factory trigger hammer pin is kept in with a wire clip through the hammer. So real hard to punch out.

Also the pistol grip screw is Loctited in and is an Allen key head, so real hard to get out. I've stripped the head on mine.
