I have this ar15 upper from mega arms bought in california before the gun law change. I had no idea they went out of business. The currect hand guard is 7 inches. I want to upgrade to 9 or 10 inches. This came as a set and was constructed to fit each other. I dont know of a hand guard that would fit this. All hand guards seem to have a barrel nut that comes with it to fit the threads of the upper. But if you look close there are no threads because it's a matching set. Help or advice on what I should be searching for online so i dont have to buy and keep returning. Thank you

Thats an MKM upper, and the pieces were not sold separately.

Zev Technologies bought Mega, so try emailing or calling them.

JSE surplus might have some mega mml sets in stock

Now they only have wedgelock uppers ill ask and see if they are compatible. Thanks for pointing out it is mkm

They are not.
