I've ears the gun sites threads are shouldered on the front sight, so be careful to check for concentricity. I've only seen one person who's had a problem with it.
thanks for the info! make sure to keep that in m ind for sure if i ever have the cash for a can. although ive had a small devil on my shoulder telling me to put my gunsite up for trade for an nice AR in 300BO...Daniel Defense would be nice....the devils just small right now, im hoping he doesnt get bigger! lol!
